NUCLEAR MEDICINE BONE IMAGE ANALYSIS TECHNOLOGY

摘要

PROBLEM TO BE SOLVED: To provide a technology that assists an imaging diagnosis of a bone tissue, using a SPECT or a PET.SOLUTION: A bone image conversion processing program includes: getting access to three-dimensional image data obtained from a subject on the basis of single photon emission computed tomography using a radioactive tracer for a bone tissue or positron emission tomography; storing a value relating to an amount of radioactivity administered to the subject in a memory for conducting the single photon emission computed tomography or the positron emission tomography; storing a value relating a weight of the subject in the memory; storing a value of at least one pixel of the three-dimensional image data in the memory, provided that the value represents radiation concentration of a bone region derivative pixel and is stored; calculating an intake amount of a normalization bone expressed by (radiation concentration of bone region derivative pixel)/(amount of radioactivity administered to subject for conducting the tomography)/(weight of subject) as to at least one pixel; and storing a value relating to the calculated normalization bone intake amount in the memory.
