Radiation image taking system
First Claim
1. A radiation image taking system comprising a tomosynthetic image taking means which takes an x-ray image of an object in each of a plurality of positions of an x-ray source to obtain a desired tomogram of the object by adding up the x-ray images thus obtained, a heartbeat phase detecting means which detects the heartbeat phase of the object, and a tomosynthesis control means which controls the tomosynthetic image taking means to take an x-ray image of the object in each of the plurality of positions of the x-ray source when the heartbeat of the object detected by the heartbeat phase detecting means is in the same heartbeat phase.

Abstract
A tomosynthetic image taking apparatus takes an x-ray image of an object in each of a plurality of positions of an x-ray source to obtain a desired tomogram of the object by adding up the x-ray images thus obtained. A heartbeat phase is detected and the tomosynthetic image taking apparatus is controlled to take an x-ray image of the object in each of the plurality of positions of the x-ray source when the heartbeat of the object is in the same heartbeat phase.

7. A radiation image taking system comprising
a tomosynthetic image taking means which takes an x-ray image of an object in each of a plurality of positions of an x-ray source to obtain a desired tomogram of the object by adding up the x-ray images thus obtained, a heartbeat phase detecting means which detects the heartbeat phase of the object, a storage means which stores the x-ray image of the object taken in each of the plurality of positions of the x-ray source, and a correction means which corrects at least a part of the plurality of the images taken in the plurality of positions of the x-ray source so that they are all in the same heartbeat phase on the basis of the heartbeat phases detected by the heartbeat phase detecting means when the images are taken.

11. A computer-readable medium on which is recorded a computer program for causing a computer to execute the steps of
reading out x-ray images of an object each of which is taken in a plurality of positions of an x-ray source and which can provide a desired tomogram of the object by adding up them, and heartbeat information representing the heartbeat phase of the object when the x-ray images are taken, and correcting at least a part of the plurality of the images taken in the plurality of positions of the x-ray source so that they are all in the same breathing phase on the basis of the breathing phases of the object when the images are taken.
