  1. Endoscopic TOFPET (Time of Flight Positron Emission Tomography)& Ultrasound Inna gertsenshteyn March 24, 2014 Working with: GiacomoCucciati and Marco Pizzichemi Head of Project: EtiennetteAuffray

  2. Overall Projects and Goals

  3. Focus Pancreatic Cancer Prostate Cancer • 5-year survival rate: 6% • 4th leading cause for cancer-related death in Western countries • No reliable method for early detection (yet) • Standard procedures: Ultrasound and CT scans • Lack metabolic information • 6th leading cause for cancer-related death amongst male population worldwide • Good prognosis if cancer confined to prostate and treated aggressively • Standard procedures: Ultrasound and MRI • Lack metabolic information

  4. Ultrasound Ultrasound Ultrasound

  5. Fluorodeoxyglucose (FDG) injected into body FDG is basically radioactive glucose Cancerous cells process glucose differently to normal cells FDG releases positrons, which break down and release gamma waves PET scanner detects gammas Images from scan highlight how FDG is broken down in body, giving insight into tumors’ metabolism TOF = Time of Flight LOR = Line of Response Typical Full-Body PET Scan

  6. Endoscopic PET probe

  7. Close-up of probe Ultrasound

  8. What I Do Currently working on simulation of phantom pancreas and surrounding organs/bones (just in case, here is the pancreas)

  9. Preliminary phantom prostatecreated on GAMOS 5.0.0(to be used in future simulations) Spine Detector Plate Bladder Prostate PET Colon

  10. What I Do Testing physical and scintillation properties of various crystals
