5. Partial Volume Correction

This is the final step necessary for partial volume correction of regional time-activity curves from the dynamic PET images. This is performed within MATLAB by invoking a script called pvc.m (You need to make sure it is in your path). command: 
>> pvc('tac_slice','matrix_slice','PET_file')
>> help pvc for more information

where:
  • tac_slice and matrix_slice are respectively the geometric transfer matrix (GTM) for each PET slice, and the time-activity curves (TAC's) provided by step 4
  • PET_file is the original -dynamic- PET volume .
