Within the PET Center, PC's and MacIntosh computers are used for data acquisition, reconstruction, and initial viewing of images. MedImage software is used by physicians to read patient studies. Image analysis (ROI drawing and image math) and physiological modeling (quantitative FDG, Patlak, blood flow) are done routinely on dynamically acquired data sets. High speed Linux processors are used for Monte Carlo simulations of detector design. Specialized image analysis programs have been developed in Siemens ICON and research systems IDL software. MEDx software (Sensor Systems) running on a Linux system provides SPM image coregistration and rapid image processing functions.
