DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiation detecting cassette containing a radiation detector, and more particularly, to a radiation detecting cassette having display means for displaying information required for photographing such as a photographing menu.

[0002]

2. Description of the Related Art Conventionally, it has been generally practiced to irradiate a subject such as a living body with radiation and detect the radiation transmitted through the subject with a radiation detector of a radiation detecting cassette to photograph a radiation projection image.

For example, as an example of such a detector, Japanese Patent Application Laid-Open No. 7-140255 and US Pat.
A cassette for a radiation detector disclosed in JP-A-09-0909 is known. More specifically, this radiation projection image is converted by the scintillator into visible light that emits light at an intensity corresponding to the intensity of the projection image. The converted visible light is received by a solid-state detection element two-dimensionally arranged on the radiation detector and is photoelectrically converted. This photoelectrically converted image signal is stored in the image memory. Thereafter, the image signal is sent to a signal processing device outside the cassette, and a radiation image of the subject is reproduced as a visible image.

As a detector that does not require a scintillator, a solid-state radiation detector using CdTe or the like (Japanese Patent Application Laid-Open No. 1-216290) is known. Radiation solid state detector (Metal / AmorphousSilicon Multilayer Radiat
ion Detectors, IEE TRANSACTIONS ON NUCLEAR SCIENC
E.VOL.36.No.2.APRIL 1989) is known. In this direct conversion type solid-state radiation detector, a capacitor is connected to each charge collection electrode, and the charge collected by each charge collection electrode is stored as a latent image charge carrying image information in the capacitor. You.

[0005] The imaging of a patient (subject) is controlled by a part called a console of an imaging apparatus at a predetermined location in an imaging room. At that time, the patient brings a radiograph with the doctor's instructions written on it, or the doctor's instructions are transferred to the console via the network, and the radiologist sees the information to obtain ID information, radiographing methods, radiographing areas, etc. I have the information I need. Then, the radiologist sets the imaging conditions on the console based on the information, and arranges the radiation detection cassette at the imaging site to perform imaging. In some cases, a series of multiple images with different imaging methods and different imaging sites may be performed on the same patient, in which case the radiologist refers to the doctor's instructions for each imaging to determine the imaging conditions. It is set and the radiation detection cassette is placed.

[0006]

In the above-mentioned conventional example, it is necessary to confirm a part to be photographed with a console or the like, and then go to the photographing place to arrange the cassette. In particular, when performing a series of multiple images with different imaging methods and imaging regions, 1
Check the imaging part and imaging order by console etc. for each image,
Each time it is necessary to arrange the cassette at the shooting location, it is very complicated. Depending on the part to be imaged, the conditions for imaging differ, and preparations corresponding to the conditions are required. For example, it may be necessary to replace the grid with a pitch that is optimal for the imaging region.

Further, in order to confirm whether or not the patient at the imaging location is the patient to be imaged, it is necessary to check with the patient after looking at the above-mentioned imaging slip or console, which is troublesome. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and when a radiation projection image of a patient is taken, a photographing menu such as a photographing condition, a photographing method, a photographing site, etc. can be known at a photographing place. An object of the present invention is to provide a radiation detecting cassette.

It is still another object of the present invention to provide a radiation detecting cassette capable of knowing ID (identification) information such as a patient's name or the like at an imaging place.

[0010]

According to the present invention, there is provided a radiation detecting cassette according to the present invention, comprising: receiving means for receiving information required for imaging from outside, that is, a console, at the time of imaging; and displaying means for displaying information received by the receiving means. It is characterized by having. With this display means, a radiographing menu or the like necessary for radiography is displayed on the radiation detecting cassette.

The display means can be provided on the surface opposite to the surface irradiated with the radiation.

Here, the receiving means includes a terminal, a circuit, a connector, an antenna and the like for receiving a signal from a wired or wireless external source.

[0013]

The radiation detecting cassette according to the present invention has a receiving means for externally receiving information necessary for imaging at the time of imaging, and a display means for displaying information received by the receiving means. At this time, since information such as a photographing menu necessary for photographing the subject can be known at the place of photographing, there is no need to return to the console for confirmation, and efficient photographing can be performed without fail. This is particularly effective when the subject is a child and it is necessary to take a picture clearly because it is necessary to hold down the subject during photography. Furthermore, when imaging of a plurality of parts is necessary, it is possible to confirm the order of imaging and whether or not it is necessary to change the grid due to a difference in imaging conditions on the spot, so that there is no risk of making a mistake and the work is efficient. Can be done. Since the patient information such as the ID can be confirmed on the spot, it is possible to avoid a problem that the patient is mistakenly recorded. When the display means is provided on the side opposite to the surface to be irradiated with radiation, it is more effective since the irradiation surface is not reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a rear view of a radiation detecting cassette (hereinafter simply referred to as a cassette) 1 according to a preferred embodiment of the present invention. The cassette 1 has a substantially flat rectangular case 2 and a similarly flat radiation detector (hereinafter simply referred to as a detector) 4 housed in the case 2. Also,
Although not shown, the case 2 usually includes a power source such as a battery. A large number of solid-state detection elements (not shown) are two-dimensionally arranged on the detector 4. Here, the solid-state detection element, that is, the solid-state sensor is usually formed on a glass substrate, but in the present invention, the substrate material is preferably made of resin (plastic). This is because, since the cassette 1 is used while being carried, the substrate accommodated in the cassette 1 is required to have an impact resistance that does not easily break even if dropped or the like and a light weight that facilitates carrying. Since the solid-state sensor is exposed to a high temperature or a chemical is used when the solid-state sensor is formed on the substrate, the substrate material is required to have high-temperature resistance and chemical resistance. Nippon 10-23282
In the optical reading method disclosed in No. 4, that is, a method of reading out latent image charges accumulated in the solid-state sensor by irradiating the reading light as an electric signal, light transmittance for transmitting the reading light is required. Specific examples of the resin substrate material having high temperature resistance and chemical resistance include polyimide and the like, and if it is heat-treated to be colorless, it can be used as a substrate material having light transmittance. The radiation projection image detected by the detector 4 is stored in the image memory 6 as an image signal, and is connected to an external device (not shown) by an external connection means 8 such as a connector as necessary, and is converted to a radiation image of the subject as a visible image. Will be played.

A display device (display means) 10 such as a liquid crystal panel is arranged on the back of the case 2. The display device 10 includes display processing means such as an X and Y address circuit and a control circuit for displaying. The display device 10 displays information received from a connection unit (reception unit) 12 that receives an operation from an external console or the like or a signal from a control unit (not shown). The connection unit 12 is wired, that is, a cable (not shown)
When it is connected to a terminal, it becomes a terminal and a connector, and when it receives a signal transmitted by radio, it becomes an antenna and an associated radio reception processing circuit (not shown).

The display device may be, for example, a liquid crystal panel. The display device 10 displays a serial number of imaging, gender, name, age, imaging region, direction, image size of the patient, the order of imaging when there are a plurality of imaging regions, etc. There is no need to return to the console because the user can check on the spot and give necessary instructions.

The display device is preferably provided on the back side of the cassette 1 to which the radiation is not irradiated, because it does not obstruct the detection surface of the detector 4. When it is provided on the front side, it is provided at the corner avoiding the center of the detection surface. Regardless of whether it is provided on the front side or the back side, the photographer can check the display screen each time a plurality of locations are photographed. The shooting menu is transmitted from the console each time shooting is performed, but can also be transmitted collectively.

Although the preferred embodiment of the present invention has been described in detail, the present invention is not limited to this embodiment, and various modifications and changes can be made. For example, the display device 10 may have a vertically or horizontally elongated shape so as to avoid the detector 4. Further, the remaining amount of the image memory 6 may be displayed.
