Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiographic image capturing apparatus, a radiographic image reading apparatus, and a radiographic image information recording medium used for capturing a medical image.

[0002]

2. Description of the Related Art Radiation images using X-rays and the like are widely used as medical images for diagnosing diseases. In order to obtain this radiation image, X-rays transmitted through the subject were irradiated on a phosphor layer (fluorescent screen), thereby generating visible light, and using the visible light as a silver salt as in a normal photograph. So-called radiographs, which have been developed by irradiating a film, have been widely used.

However, in recent years, a method has been devised for directly taking out an image from a phosphor layer without using a film coated with a silver salt. This includes:
The radiation transmitted through the subject is absorbed by the phosphor, and thereafter, the phosphor is excited by, for example, light or heat energy, thereby emitting the radiation energy accumulated by the phosphor as a result of the absorption. There is a method of obtaining an image signal by photoelectrically converting fluorescence. That is, this phosphor is used as a radiation image conversion plate.

[0004] Specifically, for example, US Patent No. 3,859,527
And JP-A-55-12144, etc., show a radiation image conversion method using a stimulable phosphor and using visible light or infrared light as stimulating excitation light. In this method, a radiation image conversion plate having a stimulable phosphor layer formed on a support is used. A latent image is formed by accumulating radiation energy corresponding to the radiation transmittance of each part of the specimen, and thereafter, the accumulated radiation energy is emitted by scanning the photostimulable layer with photostimulated excitation light, and this is irradiated with light. The optical signal is photoelectrically converted to obtain a radiation image signal.

The radiation image signal thus obtained is output as it is or subjected to image processing to a silver halide film, a CRT or the like to be visualized, or is filed in an electronic filing device.

In addition, instead of the above-described radiation image conversion plate, a radiation image detector that directly outputs an electric signal corresponding to the dose of irradiated radiation may be used.

[0007]

The radiation image read from the radiation image conversion plate or the radiation image output from the radiation image detector is electrical image data that can be processed by a computer. For this reason, by performing processing such as image rotation or image inversion, the orientation of the original image (subject) may not be known.

When reading images, the orientation of the original subject is important. If the orientation is incorrect, serious medical mistakes such as erroneous diagnosis and erroneous surgery may occur. Therefore, a technique of taking a mark called a marker beside a subject at the time of photographing and taking the image together is commonly used. However, photographing with such a marker placed beside the subject is troublesome, and furthermore, there is a problem that it is impossible to eliminate mistakes at all due to work performed by humans.
