Problems solved by technology

However, the size of the image may change due to the growth of the subject or the deviation in the setting, etc.
The images of different sizes formed in this way are not intuitive when compared and observed, and are prone to errors when the comparison of sizes is important.

Embodiment Construction

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 is a block diagram of the X-ray imaging device in the embodiment, figure 2 is a schematic diagram showing an FPD drive structure related to drive of a flat-panel X-ray detector, image 3It is a schematic diagram showing a schematic configuration of an X-ray drive unit related to drive of an X-ray tube. In this embodiment, a flat-panel X-ray detector (hereinafter, abbreviated as "FPD") is used as an example of the radiation detection means, and an X-ray imaging device is used as an example of the radiation imaging device.

[0013] Such as figure 1 As shown, the X-ray imaging device has: a bed board 1, which places the subject M; an X-ray tube 2, which irradiates X-rays to the subject M; . The X-ray tube 2 corresponds to the radiation irradiation unit in this invention, and the FPD 3 corresponds to the radiation detection unit in this invention.

Abstract

A radiation imaging apparatus has an image synthesizing means and a setting means. When obtaining a long image in a longitudinal direction, the image synthesizing means synthesizes, in the longitudinal direction, a plurality of radiation images formed based on the detected radiation, and the setting means sets the longitudinal length of the radiation images to be synthesized. Therefore, the setting means for setting according to the longitudinal length of the radiation images to be synthesized makes it possible to set the length without requiring to enlarge or reduce the radiation images of atarget portion, so that the target portion can be always scaled in the same manner, causing mistakes to hardly occur.

Description

technical field [0001] The present invention relates to a radiographic apparatus that performs radiographic imaging, and particularly relates to a technology in which a radiation irradiating unit and a radiation detecting unit move in parallel to face each other in the same direction along the longitudinal direction (longitudinal direction) of an object. Background technique [0002] Conventionally, there is a method of moving an X-ray tube (radiation irradiation unit) and an X-ray detector (radiation detection unit) parallel to each other in the same direction along the body axis of the subject to obtain multiple An X-ray imaging device for an X-ray image (for example, refer to Patent Documents 1 and 2). Based on a plurality of X-ray images obtained by this apparatus, by synthesizing them in the body axis direction, that is, in the longitudinal direction, an X-ray image of the long side region (long side X-ray image) can be obtained.
