ANZ Branch Webinar: Spectral, DECT & PMCT
October 26, 2022 @ 20:00 - 21:00 AEDTFree – $10
Join the ANZ branch of the IAFR for their next webinar “Spectral, DECT and Post-mortem CT (PMCT)” presented by Dominic Gascho and Dr Tomoya Kobayashi.
Mr. Dominic Gascho is Manager of Medical Technical Radiology at the Forensic Institute, University of Zurich and is head of the Post-mortem Imaging Technology research group (a subdivision of the Virtopsy research group). He studied radiologic technology in Austria. After three years of clinical radiology, he switched to forensic post-mortem radiology and imaging and joined the Virtopsy group in September 2012. From 2020 to 2022, he deepened his knowledge in imaging with a university master’s degree in medical physics at the Swiss Federal Institute of Technology (ETH) in Zurich.
The new technology of photon-counting computed tomography enables new possibilities in forensic imaging. On the one hand, this semiconductor detector technology enables higher resolution (subpixels), lower noise (signal threshold), as well as better soft tissue contrast due to good image quality even at lower energies (constant dependence of detector responsivity to energy). On the other hand, new possibilities arise in material differentiation (virtual mono-energetic imaging and “energy-bin” imaging). This webinar will provide a brief introduction to the photon-counting detector technology and potential applications in forensic imaging.
Dr Tomoya Kobayashi:
Dr Tomoya Kobayashi (RT, Ph.D.) is an Assistant Professor for the Clinical Imaging Department at Tohoku University, and for the Legal Medicine of Social Medicine Department at Nihon University School of Medicine. Dr. Kobayashi is a member of the Post-mortem Imaging Committee, The Japan Association of Radiological Technologists and is currently a director of the Japan Society of Autopsy imaging, and Vice President of The Japanese Society of Autopsy imaging and Technology (JSAiT).
Post-mortem CT (PMCT) is effective in determining the cause of death especially from haemorrhagic causes. Contrast-enhanced PMCT angiography and post-mortem MRI have been reported to detect intravascular embolisms and soft tissue changes, but are not widely used due to relatively long scan time and the expensive cost. As high radiation exposure and dosage is not an issue for a corpse and the body does not move during PMCT, repetitive scanning of the same site is possible, which adds to the image data of the target site. This X-ray summation method applied at PMCT is called “fused PMCT”. Our pilot study showed that the fused PMCT reduced image noise and could clearly delineate the coronary arterial wall and hypostasis in the lumen by scanning the same site repeatedly. This webinar will present the fused PMCT procedures and various case studies.
