Operating a Value-driven Medical Physics Consulting Practice in Canada: Perspectives and Experiences
Jeff Frimeth, JF Medical Physics Inc.

JF Medical Physics Inc. has been providing consultant-based medical physics services since 2017 and is operated by President & Chief Medical Physicist Jeff Frimeth. The company has grown both in personnel, clientele, and scope of practice over the years. Many reasons have attributed to this growth, with the primary reason being our ability to continue to provide (more) value-driven services. It has been our experience that focussing our efforts on providing value (i.e. a Medical Physics 3.0 type approach), while ensuring we cover all grounds in terms of regulatory and/or accreditation requirements not only "checks the box", but also allows us to further engage facilities in advancing their quality control and/or radiation safety programs. Through experience, we have adapted our approach to not just "do the job" but to also educate and teach our clients on aspects related to best practices which can lead to improvements in overall workflow, decease costs, and improve efficiencies. Our clients generally do not have any degrees in medical physics and sometimes do not have any technical background in radiation safety/quality control at all. While, consulting has been a very worthwhile endeavour, it is not without its challenges. Not only is there a technical aspect to our consulting services, there are also numerous business aspects, and psychological aspects. Anecdotal experience and observations in the years of consulting services provided will be shared and discussed.

Safety Considerations for Clinical Magnetic Resonance Imaging
Ives Levesque, McGill University

Magnetic resonance imaging is often described as the “safe” modality, largely due to the absence of ionizing radiation. But, magnetic field interactions give rise to multiple hazards that have led to serious incidents. While modern MR systems are designed with many features that enhance patient and staff safety, safety in the MR environment ultimately relies heavily on human factors to mitigate risk. In this presentation, I will briefly review some basic principles of MR safety before delving into my activities in this area. I will describe my efforts in clinical MR safety at the McGill University Health Centre, touching on policy, procedures, training, and patient screening. Following this I will describe my research activities in MR safety. These include (1) a recent review of patient screening practices at the Department of Radiation Oncology of the McGill University Health Centre,  (2) work of AAPM Task Group 334 on MR safety considerations for radiation therapy accessories, (3) the quantitative assessment of MR safety guidance based on the hierarchy of hazard controls, and (4) a comparative review of environmental assumptions commonly seen in clinical MR safety guidance

Xinchi Hou, University of British Columbia

The SPECT/CT camera equipped with a cadmium zinc telluride (CZT) detector is gradually replacing traditional NaI(Tl) systems due to its potential to deliver enhanced image contrast, resolution, and sensitivity while enabling faster scans or lower-dose procedures. This advancement is well established for Tc-99m scans; however, there is limited information on I-123 imaging, which is the primary method for neuroblastoma diagnosis, particularly in pediatric cases where lower doses are used compared to adults. Recently, a dedicated CZT camera was suspected to have image artifacts related to cold (no activity uptake) and hot (unexpected activity uptake) areas within the I-123 image volume, as reported by our Nuclear Medicine (NM) Physician, highlighting the need for camera performance evaluation for I-123 scans. Beyond image quality, the quantification of lesion uptake may enhance therapy monitoring for neuroblastoma. In this presentation, we will share our experience on camera performance evaluation, investigation of image quality and quantification of I-123 imaging, delivered from both phantom and patient studies.

The GE NM/CT 670 CZT camera, equipped with a wide energy high resolution (WEHR45) collimator, was utilized in these studies. For phantom studies, the standard Jaszczak phantom, with/without cold spheres and rods, was used to assess image quality, while the NEMA IEC phantom with radioactive spheres was employed for further evaluation of both image quality and quantification by evaluating background variability, contrast-to-noise ratio, and contrast recovery coefficients across different signal-to-background ratios. The impact of scatter correction via the triple-energy-window method was also examined. These results were then compared to the images obtained from NaI detector of the same SPECT/CT model. The feasibility of using the CZT camera for I-123 scans will be discussed based on both phantom studies and clinical pediatric scans, along with recommendations for annual quality control and clinical scanning protocols.

R.Milman_Headshot2Framing Risk and Benefit in Medical Imaging
Rebecca Milman, University of Colorado School of Medicine

Much of modern clinical medical imaging is a continuous evaluation of benefits and risks associated with various exams. While most would agree that there are clear benefits and risks, these are often difficult to quantify. This presentation will delve into how benefits and risks are often discussed, the limited quantitative data currently available, and the uncertainty in existing knowledge. Finally, we will explore the effect this has on policy and clinical practice, including the use of dose metrics, patient shielding, and patient interactions.

Advancing Gynecological Imaging: The Role of Hybrid AI in Ovarian Cancer Diagnosis
Heather Whitney, University of Chicago

Artificial intelligence (AI) can support clinical practice by automating complex tasks in medical imaging, such as tissue segmentation and characterization—processes that often difficult for humans to complete but are critical for accurate diagnosis. Hybrid AI, which integrates multiple AI methodologies, can further enhance these imaging pipelines. This talk will explore the application of AI in gynecological imaging, with a particular focus on ultrasound. I will present an end-to-end hybrid AI pipeline specifically designed for diagnosing ovarian cancer using ultrasound images, demonstrating how this approach can effectively manage the challenges posed by the heterogeneous nature of ovarian masses.
