Title:
DATA PROCESSING METHOD, PROGRAM, DATA PROCESSING APPARATUS, AND POSITRON EMISSION TOMOGRAPHIC IMAGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/059135
Kind Code:
A1
Abstract:
This data processing method comprises: a step for converting TOF measurement data into non-TOF measurement data that does not include TOF information (S2); a step for generating a non-TOF reconstructed image by performing at least a random correction process, a scattering correction process, and a reconstruction process on the non-TOF measurement data (S3); a step for generating TOF projection data including TOF information by forward projecting the non-TOF reconstructed image (S4); and a step for estimating a bias component included in the TOF projection data on the basis of the TOF measurement data and the TOF projection data (S5).
