The Princess Margaret “Transformers”

4 PRINCESS MARGARET CANCER CENTRE GUIDED THERAPEUTICS OPERATING ROOM - GTxOR WE BUILT: GUIDED THERAPEUTICS OPERATING ROOM (GTxOR) * DUAL-ENERGY CT ENDOSCOPY UNITS The Guided Therapeutics Operating Room (GTxOR), part of the Princess Margaret Cancer Program, is the most technologically advanced research operating facility in Canada. The unique systems allow our cancer experts to see what’s going on inside a patient before, during, and after surgery. The team in the GTxOR can acquire high-resolution computed tomography (CT) images during surgery to inform clinical decision- making in real time. This technology enables new, minimally-invasive surgical procedures in the head and neck, lungs, heart, and vascular systems. Surgical Oncologist Dr. Jonathan Irish Medical Physicist Dr. Robert Weersink and Radiologist Dr. Walter Kucharczyk along with a multi-disciplinary team of specialists, led the development of the GTxOR. It was made possible through a collaboration with the Techna Institute, a research and development centre at University Health Network (UHN) designed to improve patient outcomes through technology. ROBOTIC CONE-BEAM CT • Acquires CT images without moving the patient •Multi-axis robotic arm moves the x-ray source around the patient during imaging • X-ray images form a three- dimensional (3D) picture of the patient’s cancer CONTROL ROOM • Technicians in the control room support the surgical team by controlling the systems that acquire, process and display 3D images DUAL-ENERGY CT • CT uses two x-ray sources simultaneously to reduce imaging time • X-ray sources enable dual- energy techniques differentiating cancer from healthy tissue CUSTOMIZED SURGICAL TABLE • Technology allows the patient on the surgical table to be easily moved to various areas of the operating room during and after surgery
