Abstract
Official abstract text for this publication.
According to one embodiment, an apparatus includes a reconstructing unit, a first control unit, a detecting unit, a generating unit, and a second control unit. The first control unit controls the reconstructing unit to reconstruct first images based on projection data collected in first periods. The detecting unit detects second periods which belong to pulsation cycles different from one another and in which an organ to be imaged is in the substantially same form, based on the first images. The generating unit generates data for reconstruction including projection data for the required angle range by combining projection data collected in third periods close to the second periods. The second control unit controls the reconstructing unit to reconstruct a second image based the data for reconstruction.
First claim
Opening claim text (preview).
What is claimed is: 1. An imaging apparatus comprising: a scanner that collects projection data of an organ pulsating in a subject in each of a number of projection directions by use of X-rays during a collection period including at least two pulsation periods of the organ to be imaged; a computer configured to execute program instructions to produce an object image of the organ based on the collected projection data; and a memory storing program instructions which when execut…
