Dual CCD Camera Therapy Simulator CT
1 R43 CA62627-01A1,
Computed tomography (CT) has become increasingly important in radiotherapy planning: CT add-ons havintroduced for therapy simulators, and specialized CT scanners have been developed as stand-alone thsystems. However, because of therapy simulator limitations, CT add-ons have poor throughput and thussufficient image slices for adequate therapy planning. CT-based simulators have better throughput, bproduce does not have accurate enough positional information, since they do not duplicate the physictherapy machines. We plan to improve throughput of CT add-on equipment by using volume CT imaging. Cons use line sensor cameras or linear detector arrays in front of the simulator's image intensifier.because the image intensifier camera lacks the dynamic range necessary for scanning large fields ofthe human body). We will use a dual camera and optics scheme that will solve the dynamic range problreconstruction to be performed on large data sets. If successful, this technique will increase throuresearch already proven at BIR. Further improvements are foreseen which will be started in Phase III.
