Main target applications 1. Integrated current mode / spectral photon counting CT (”simple” conversion of existing CT systems � shortest path to clinical use and the lowest investment threshold) 1. Integrated PET/CT 2. Combined therapeutic and diagnostic imaging Wide range sensor for combined medical imaging systems PET/CT – future today Original picture from Siemens Medical Wide range sensor for combined medical imaging systems PET/CT Hybrid of two basic imaging modalities CT scanner (high-resolution anatomical images) PET scanner (high-quality functional images) Computer and software fuses images No patient movement between registrations “Look into the body and see what happens there (on a molecular level)” CIREA AB Wide range sensor for combined medical imaging systems PET/CT – possible implementation in CT mode CIREA AB Wide range sensor for combined medical imaging systems CIREA AB Original picture from Siemens Medical CIREA AB
Integrated standard / spectral photon counting CT system Counts and characterizes individual X-ray photons Can measure the energy of every detected X-ray photon and achieve better image contrast sensitivity for a given dose Needed for pediatric examinations and 3D mammography where dose is a key factor System includes high count rate capability of standard CT for conventional examinations Dynamic switching between modes Wide range sensor for combined medical imaging systems IP – CIREA AB “System and method for photon detection”, B. Cederwall /CIREA AB Priority date April�2,�2007 Priority number, designated state(s), status SE20070000825 SE Granted Further applications , designated state(s), status SE531025 (C2) SE Granted Further applications , designated state(s), status EP2132541 (A1) EP Granted Wide range sensor for combined medical imaging systems Integrated Portal – diagnostic (CT/SPECT/PET) imaging for cancer therapy Today’s diagnostic imaging is typically performed separate from radiation therapy sessions This reduces accuray in cancer treatment due to patient movement, anatomical changes with time (dose delivery usually via multiple sessions over several weeks) (Large effort on IMRT and planning, less on this problem) Therapeutic imaging yields poor resolution and contrast and requires high-rate radiation hard sensors. Large potential gain with integrated therapeutic and diagnostic detector system Solution: wide-dynamic-range radiation sensor � Identical patient – detector alignment � High-quality fused anatomical and therapeutic images � Lower dose to healthy tissue, higher killing power (lower recurrence rate) CIREA AB Wide range sensor for combined medical imaging systems Where we are Proof of concept established IP protection in place Basic prototype demonstrator near completion CIREA AB Wide range sensor for combined medical imaging systems CIREA AB CIREA AB
