<P>PROBLEM TO BE SOLVED: To accurately grasp radioactivity of a radioactive medicine administered to an examinee. <P>SOLUTION: A PET apparatus 100 has a timepiece section 16. The timepiece section 16 has a time measuring part 16a for measuring a time and a reference time receiving part 16b for receiving a reference time. Furthermore, the PET apparatus 100 has a detection time correction section 27a. The detection time correction section 27a corrects a detection time recorded by using the time measured by the time measuring part 16a by using the reference time received by the reference time receiving section 16b. For example, the detection time correction section 27a calculates a time error generated within a photographing time in predetermined photographing by using the time measured by the time measuring part 16a and the reference time received by the reference time receiving part 16b, and distributes the calculated time error to each of the detection times recorded within the photographing time, thereby correcting the detection time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
