Mobile Chest X-Rays Through Glass - ACPSEM press release and publication
by David Lurie, on 2020-07-21 11:40:19X-RAYS THROUGH GLASS - A TECHNIQUE TO MINIMISE INFECTION WHILE TREATING COVID-19An innovative technique for performing mobile chest x-rays through glass has been outlined in a new study by Australian medical physicists in ACPSEM’s journal “Physical and Engineering Sciences in Medicine”. The ‘through glass’ method will help speed-up treatment rates and minimise infections during the COVID-19 pandemic.Chest x-rays are key in diagnosing and managing COVID-19 patients with respiratory symptoms. The ‘through glass’ method adds an extra layer of protection by allowing x-ray images to be taken through glass from outside a patient’s room. The evidence-based technique has recently been implemented at The Alfred and Sandringham Hospitals and has the potential to improve safety in medical facilities around the world.The study ‘Technique, radiation safety and image quality for chest X-ray imaging through glass and in mobile settings during the COVID-19 pandemic’ reveals that the time taken to perform a chest x-ray for COVID-19 patients is significantly reduced by avoiding a full disinfection of the x-ray unit, adding instantly and safely to available surge capacity in our hospitals.The risk to radiographers of infection is also halved by the ‘through glass’ technique. Instead of two radiographers being in the room with the infected patient, only one is required.While x-rays through glass have been used elsewhere, this study is the first to comprehensively review all the technical and safety aspects. “X-rays through glass provide acceptable image quality, maintain low radiation doses and minimise the amount of personal protective equipment (PPE) required,” said lead author and Alfred Health Chief Imaging Physicist, Dr Zoe Brady.The study also acts as a comprehensive ‘how to’ guide for others who want to implement the ‘through glass’ method into clinical practice. “We provide evidence on all aspects including image quality, technique and radiation safety,” Dr Brady said. “Our parameters will help other hospitals and facilities introduce the technique safely to help deal with a second wave of COVID-19.” This has led to substantial attention from the medical community, with thousands of downloads of the paper and international interest immediately following publication.Development and implementation of ‘through glass’ chest x-rays has been a multi-disciplinary effort by medical physicists, radiographers, radiologists and research staff all keen to make a difference. “As a medical physicist, I have a role to play in the pandemic,” said Dr Brady, “I am not a frontline healthcare worker, but by enabling the use of this technique I can ensure the quality of chest x-rays for COVID-19 patients and help keep my colleagues safe.”This story about accelerated, pandemic-driven innovation; through the dedicated work of medical professionals, and including the low profile but indispensable medical physicist, is good news in challenging times.The ACPSEM is the professional body supporting medical physicists, scientists and engineers in Australia and New Zealand.For comment and further information contact:Dr Zoe Brady, Chief Physicist, Alfred Radiology and Nuclear Medicine Department and Radiation Safety Officer, Alfred HealthPh: +61 (3) 9076 2368Z.Brady@alfred.org.auSharon Flynn, CEO, ACPSEMPh: +61 (2) 8305 3909Mob: +61 0408463469Sharon.Flynn@acpsem.org.auwww.acpsem.org.auRead the full paper here:Brady, Z., Scoullar, H., Grinsted, B. et al.

Lessons learned in radiotherapy physics during the Covid-19 pandemic
by Catharine Clark, on 2020-06-29 23:08:39Dear colleagues,
The ESTRO Physics committee invites you to take part in a survey to gather the lessons learned in radiotherapy physics during the Covid-19 pandemic of 2020. The results will be used for a symposium at ESTRO 2021 in Madrid, where the experiences and solutions which have come out of the pandemic, in terms of how radiotherapy physics coped, will be discussed.
We would like to gather all experiences (both good and poorer) from all physicists working in radiation oncology, so multiple physicists may answer from the same institution and the responses will be anonymous.
It would be helpful if you can answer the questions as fully as possible, however no question is mandatory. The questions have been divided into sections on demographics, organisation of the department, changes in practice, morale and mental health and impact for the future. There are 39 questions in total and most are tick box responses and we estimate that it takes 20 minutes to answer all the questions.
The survey will be open until 12th July. Click on the link below to take part in the survey.
Thank you for your participation in this survey and stay safe

The following words (translated in English) can be found in a recently (30 March 2020) published formal document by the Dutch Ministry of Health: “I very much appreciate the involvement of these parties. Experts (intensivists, medical physicists and medical technologists) assess whether the equipment offered is (or can be made) suitable for use in the IC beds.” In both countries the number of beds in the Intensive Care Units for COVID19 patients has been tripled with the help of medical physicists who have worked non stop to make this happen.

Dear Bart we have looked at a few facemasks.
The 3M FFP3 1863 , Kolmi FFP2 and FFP3 masks showed torque and artefacts. The Kolmi FFP2 and FFP3 and were associated with considerable artefact on GRE images. Like yourselves the Halyard FFP2 mask did not exhibit evidence of ferromagnetism and produced
only minimal artefact on GRE imaging. The standard disposable Dalhousie surgical mask, which has some aluminum showed no signs of ferromagnetism with minimal local artefact. A number of physicists in other departments have looked at these too (particularly in the U.K. on the MRI physics disucssion group ) and may add to the list.RegardsPaddy Gilligan
Hello,Is there any information about MRI compatible masks (IIR/FFP2/FFP3), concerning artifacts, forces, and heating?In our deparntment we tested 2 two types ourselves and concluded:

Thyroid Cancer: Radioactive Iodine Treatment during COVID19 pandemic
In these unprecedented times we have been considering how to optimally manage our patients with differentiated thyroid cancer. We have put together the following guidance taking in to account both the risk patients face from cancer and from infection.
We recommend that all radioactive iodine treatments be halted during the COVID 19 pandemic based on the following rationale:
Low risk patients: (adjuvant setting)
- A delay in RAI is not expected to alter prognosis from DTC.
- This cohort of patients are expected to be cured and should they fall ill with severe COVID19 infection whilst radioactive their care and subsequent prognosis may be compromised.
- Once the COVID19 situation resolves, some of the patients who have had their treatment delayed may be suitable for 1.1GBq as an outpatient, thereby taking some demand off inpatient isotope facilities.
High risk patients (metastatic disease):
- The risk/benefit scenario in these clinical situations are harder to determine.
- This cohort are likely to have longer radiation protection restrictions following RAI and are also at higher risk for COVID19 infection. If a patient in this situation was to fall ill with COVID19 whilst radioactive their immediate care may be detrimentally affected.
We must also take in to account the service delivery aspects of patient care.
Resources (Staffing, room availability, supply chain):
- Most centres have limited numbers of clinical scientists able to administer, monitor, scan and calculate radiation protection restrictions. With likely imminent reduced staff levels it may not be safe to administer radioactive substances.
- With widespread travel restrictions and the potential for staff shortages affecting drug manufacture, it is uncertain if our RAI supply chain will be affected.
The recommendations have taken in to account discussions amongst UK thyroid cancer clinicians as well as general COVID19 oncological advice at local and national levels.
Recommendations will be kept under review.

Strategy for handling treatment gaps during COVID-19 - Herlev Hospital (DK)
by Eva Samsøe & Jens Edmund, on 2020-03-26 12:37:30Thank you for sharing your strategy for treatment gaps, Colin Kelly. Our local strategy for handling long treatment gaps during COVID-19 very much resemples yours with the addition of Table 3 in Gay et al. Practial Radiation Oncology (2019) 9, 305-321. This paper - also referenced by ESTRO - descripes the handling of the crisis during the hurricane Maria in Puerto Rico 2007. Currently, we are collecting a document describing the use of hypofractionated regimes, where it makes sense, categorized according to level of crisis (percentage of staff left). Here are our references in the document concerning long treatment interruptions (I will link if/when the document is online - it will, however, be in Danish):

- Use the conventional formula to calculate BED i.e. )
- Discuss with RO whether they want to match normal tissue toxicity for a particular OAR or original treatment prescribed dose
- Determine salvage course which will probably involve bi-dailies and/or weekend treatments
- We have decided not to change the dose per fraction but to stick with that of the original treatment intent
- For the time facto K and the repopulation time we are using the values set out below.
RE: For your information: Fast volume chest CT protocol used in HUS Finland
by Mika Kortesniemi, on 2020-03-25 09:41:43Due to some further questions which I have received on the fast volume chest CT protocol, here are some remarks which might be useful:
- Overall context: There are various CT scan protocols and imaging options which can be used for this patient group (=poorly or non-co-operative intensive care patients in chest CT scan) but this is what we chose to use primarily in this case. Other indications and co-operative patients are typically examined with other protocols and imaging methods.
- Patient orientation: Feet first was used to facilitate the patient access and scan preparations with intensive care patients with related instruments and tubings, and also to facilitate possible further contrast enhanced scan if that is needed for overall clinical status and indications.
- Radiation exposure: We have seen CTDIvol typically within a range of 3 to 9 mGy (depending on patient size & attenuation, we also tested the protocol with anthropomorphic phantom). The scan length is typically about 30 cm (again, varying a lot depending of the patient anatomy) which indicates a DLP ranging from about 100 to 300 mGycm. In terms of effective dose, this indicates that the exposure should be well below 5 mSv, typically 2-4 mSv.
- Scan parameters: It is important to notice that optimal scan parameters may (and will) vary between different vendors and scanner models. Furthermore, in each imaging organisation, the clinical image quality must be adjusted to satisfy radiologists preferences and requirements on each site. Thus, optimal scan parameters may involve:
- different reconstruction options (including anatomical DFOV options, selection of kernels and levels of iterative reconstruction - or more recently, deep-learning based reconstruction)
- application of organ-dose-modulation
- spectral optimisation (e.g. use of tin-filtration if applicable)
- ultra-fast scanning with dual-source or wider detector scanner models
- different number of localiser radiographs (1 or 2 scouts/topograms) and their order and projection angle (effecting ATCM and helping patient centering)
- ...and other scanner specific technical optimisation tools.

by David Lurie, on 2020-03-23 12:22:06The following article has just been published in Advances in Radiation Oncology by Krengli, Ferrara, Mastroleo, Brambilla and Ricardi:"Running a Radiation Oncology Department at the time of coronavirus: an Italian experience"The article, which is Open Access, can be found at: https://doi.org/10.1016/j.adro.2020.03.003
For your information: Fast volume chest CT protocol used in HUS Finland
by Mika Kortesniemi, on 2020-03-23 10:38:41For your information, we prepared the following modification of the volume HRCT protocol to enable fast lung scan for non-co-operative patients, primarily now thinking of covid intensive care cases (mainly for our Siemens Definition Edge/Flash/AS scanners, but also GE is referenced):
Please, note that this only for information of our local protocol. I will gladly receive comments or suggestions for improvements on this.Best regards, stay healthy,Mika
- no IV contrast used in this scan.
- Patient in feet first supine position.
- Two topograms: 1st craniocaudal lat, 2nd caudocranial top, followed by craniocaudal spiral scan.
- DFOV limited tightly to bony chest.
- Rotation time: 0.28-0.33 s or based on scanner model; as fast rotation as feasible considering tube limits.
- Tube-voltage: 120 kV (140 kV only with very obese patients) to keep it simple
- ATCM (mA-modulation): Siemens QRefmAs 110-140 depending on model (QRefmAs 110 with new Stellar detector scanners. With GE scanners: NI 30 HU (set for 0.625 mm primary recon).
- Pitch: Siemens 1.2; GE 1.0. Aiming to fast scan but considering tube limits.
- In this scan, we are quite conservative with iterative recon, but of course that's according to radiologists preferences.
- Archived images:
- Lung window images: Siemens kernel = B50f medium sharp; GE kernel = Bone Plus: axial, sagittal, coronal images with 1 mm thickness (or thinner) with same interval.
- Mediastinum window images: Siemens kernel = B30f medium smooth; GE kernel = Standard: 3 mm thick axial images with same interval
Global challenge for the fast development of ventilators to treat COVID-19
by ennomotive, on 2020-03-20 12:32:51Ennomotive has launched a non-profit online competition for the ideation of low-cost, easy-to-build solutions. The goal is to speed up the availability of ventilators in hospitals everywhere to help patients with coronavirus.The number of people affected by the pandemic doubles every three days in many countries. Since 20% of patients are hospitalized and 5% need to be admitted to an ICU, the demand for ventilators is sky-high.Ennomotive has joined other international initiatives for the development of easy-to-build ventilators and makes its global community of 20,000 engineers available to face the challenge.Based on its experience, ennomotive has chosen to focus on solutions that can adapt or reuse widely used standard industrial components or that use other easy-to-access and universal everyday-life elements.This online challenge is open worldwide to any engineering professional, company, tech center, maker or scholar from different industries and technical backgrounds that want to propose a solution for this challenge. The final goal is to make a key contribution to the fight against the COVID-19 pandemic.The solutions resulting from this challenge will be open to the public and ennomotive will fund the development of the best prototypes in the next round. Given the urgency, the first deadline for submissions is the 25th of March.

Webinar concerning COVID-19 related infrastructural problems in Dutch hospitals
by Ad J.J. Maas, on 2020-03-17 17:50:19Tuesday 17 March, a webinar was held among 100 MPEs working in hospitals in the Netherlands. Dutch MPEs have a responsibility concerning the availability and quality of medical equipment. The influx of seriously ill COVID-19 patients causes problems for the capacity of IC wards. This capacity is mainly limited by the availability of ventilators and hemodialysis or CVVH equipment. Several solutions were given how to increase the availability of these apparatus in order to increase IC capacity.The main warning was: be prepared and take your measures now!
Recommendations published by the French Society of Radiation Oncology (SFRO), the National Union of Radiation Oncologists (SNRO) and the French Society of Medical Physics (SFPM) for use by professionals working in the Radiation Oncology field.You can find the guidelines (in French) at the website of SFPM:
