C-TECC (CT Education and Collaboration Collective) is a forward-thinking program focused on educating and collaborating with radiology professionals—radiologists, technologists, physicists, and trainees—on the latest CT scanner technologies, with an emphasis on Photon Counting Detector (PCD) CT. Built on the University of Wisconsin-Madison’s mission to advance patient care, research, and education, C-TECC supports these goals through four core pillars: training, show site hosting, expert guidance, and research collaboration. By fostering an inclusive culture, C-TECC empowers radiology teams to enhance value-based, patient-centered CT imaging and drive innovation in the field.
Pillars:
Training: C-TECC offers a range of workshops for radiology professionals, including an introductory Photon Counting CT course and an advanced user group workshop. These sessions provide CE/CME credits and focus on optimizing clinical workflows and understanding the differences between energy integrating and photon counting CT technologies.
Show Site Hosting: C-TECC partners with CT scanner OEMs to host demonstrations and provide promotional content on Photon Counting CT technology. This includes offering research-focused show site visits, featuring expert-led sessions on CT experiences.
Guidance: C-TECC delivers educational materials, including protocols and case examples, through a public website to assist clinics outside of UW-Madison. C-TECC also organizes virtual Medical Advisory Board meetings and publishes guidelines for optimal photon counting and EID CT image reconstruction.
Research Collaboration: C-TECC supports research by funding weeklong visits for external researchers to collect data at UW facilities. Additionally, it funds internal UW researchers to visit external CT expert sites globally for multi-institutional collaborative projects.
