Embodiment Construction

[0042] The following is an explanation about the configuration of the radiation detector 12 according to the present embodiment.

[0043] figure 1 is a sectional view schematically showing the configuration of the radiation detector 12 according to the present exemplary embodiment; figure 2 is a plan view illustrating the configuration of the radiation detector 12 .

[0044] Such as figure 1 As shown, radiation detector 12 is configured with scintillator layer 28 interposed between photodetectors 20A and 20B. Since both the photodetectors 20A and 20B have configurations similar to each other, only the photodetector 20A will be explained below. also from figure 1 Details about the photodetector 20B are omitted in .

[0045] The photodetector 20A includes a TFT substrate 26 of an insulating substrate 22 formed using a switching device such as a thin film transistor (TFT).

[0046] The scintillator layer 28 serves as an example of a radiation wavelength conversion layer for ...

Abstract

The invention provides a radiographic image capture device and a radiographic image capture method. The radiographic image capture device includes a wavelength conversion layer that converts radiation that has passed through an imaging subject into visible light, a first photodetector that detects the converted visible light and that converts the converted visible light into a first image signal expressing a radiographic image, a second photodetector that detects the converted visible light and that converts the converted visible light into a second image signal expressing a radiographic image, and a synthesizing section that combines the first image signal read from the first photodetector and the second image signal read from the second photodetector such that misalignment between the first and the second photodetectors is eliminated.

Description

technical field [0001] The present invention relates to a radiographic image capturing device and a radiographic image capturing method. Background technique [0002] Recently, radiation detectors such as flat panel detectors (FPDs) having a radiation sensing layer disposed on a thin film transistor (TFT) active matrix substrate, detecting irradiated radiation such as X-rays, and An electrical signal indicative of a radiographic image representing the detected radiation is output. This radiation detector has the advantage of enabling more immediate confirmation of images and video images compared to conventional imaging panels. [0003] Portable radiological image capturing apparatuses (hereinafter also referred to as electronic cassettes) for capturing radiographic images mounted with such radiation detectors are also put into practical use. In surgery, it is important to be able to display radiographic images immediately after image capture to treat patients quickly and ...
