A scheme for enabling proper radiation sensing to be performed without establishing a synchronous connection by generating radioscopic and sensing timings of an image sensor, includes a timing prediction unit for predicting an x-ray pulse timing on the basis of a detection value of a first X-ray detection unit, and outputting the predicted radiation pulse timing, and a drive control unit for effecting drive control of a second X-ray detection unit on the basis of an output of the timing prediction unit, thereby making it possible to perform the proper radiation sensing without establishing the wired or wireless online synchronous connection.
A radiation sensing apparatus having a first radiation detection unit and a second radiation detection unit, comprising:
A radiation sensing method using a radiation sensing apparatus having a first radiation detection unit and a second radiation detection unit, comprising:
A program for making a computer execute a radiation sensing method using a radiation sensing apparatus having a first radiation detection unit and a second radiation detection unit, said program making said computer execute:

1. Field of the Invention
The present invention relates to a radiation sensing technology for sensing a radiation image.
2. Related Background Art
Other objects and features of the present invention will become apparent in the following discussion in conjunction with the accompanying drawings, in which:
FIG. 1 is a diagram showing a synchronous timing in an embodiment of an electronic cassette according to the present invention;
FIG. 2 is an explanatory diagram showing operation timings of respective units in the embodiment;
Next, embodiments of a radiation sensing apparatus, a radiation sensing method, a computer program and a computer readable recording medium of the present invention, will be discussed with reference to the accompanying drawings.
In the following discussion, X-rays are exemplified as radioactive rays, however, α-rays, β-rays and γ-rays may also be available.
FIG. 1 shows an example of configuration in the embodiment of the present invention. The X-rays radiated from an X-ray radiation tube 11 penetrate an object (not shown) and reach a second detector 12 (which will hereinafter be termed an X-ray imaging detector), wherein an image is formed. Then, the X-rays penetrating the X-ray imaging detector 12 arrive at a first detector 13 (which will hereinafter be simply called an X-ray detector: the X-ray detector or photo timer defined in Japanese Patent Application Laid-Open No. 11-151233), wherein Start and Stop of the irradiation are detected.
