Abstract

An X-ray imaging apparatus which obtains an X-ray image, the apparatus includes: an imaging unit including a plurality of detecting elements adapted to convert X-rays generated by an X-ray generating apparatus which outputs or stops X-rays in accordance with an operation instruction into an image signal; and an obtaining unit adapted to obtain an operation start timing of the X-ray generating apparatus based on an image signal output from the imaging unit and obtain a difference between a timing of an operation instruction to the X-ray generating apparatus and the operation start timing.

First claim

What is claimed is:

1. An apparatus connectable to an X-ray detector adapted to acquire an X-ray image by a plurality of detecting elements which acquire electrical signals if X-rays are irradiated thereon from an X-ray generator, comprising:
a first obtaining unit adapted to obtain output timing of a control signal for changing a generating status of the X-rays in the X-ray generator based on a signal from the X-ray generator;
a second obtaining unit adapted to obtain change ti…
