Abstract:
1. A tomogram creating method, comprising the following steps: acquiring first radiation signals, while a body to be examined ceases breathing, with respect to radiation transmitted through the body; a first structural tomogram creating step for creating data to be used for constructing a first structural tomogram, based on said first radiation signals; acquiring second radiation signals, while the body to be examined is breathing, with respect to radiation transmitted through the body; a second structural tomogram creating step for creating data to be used for constructing a second structural tomogram, based on said second radiation signals; a correction information creating step for creating correction information to be used for correcting image blurring of said second structural tomogram with respect to said first structural tomogram, based on the data to be used for constructing said first and second structural tomograms; acquiring third radiation signals, while the body to be examined is breathing, with respect to radiation emitted from the body to be examined due to a radioactive medical agent; and a functional tomogram creating step of creating a functional tomogram, based on said third radiation signals and the correction information.
