Description

X-ray equipment

The present invention relates to an X-ray imaging apparatus that performs X-ray imaging or X-ray fluoroscopy.

Such an X-ray imaging apparatus includes an X-ray irradiation unit having an X-ray tube, and an X-ray detector such as a flat panel detector that detects X-rays emitted from the X-ray irradiation unit and passed through the subject. A line detection unit, and a console unit arranged in an operation region in an X-ray imaging room for controlling the X-ray irradiation unit and the X-ray detection unit. At this time, as the X-ray detector used for X-ray imaging, a plurality of types having different sizes and the like are used depending on the imaging mode. Also, in recent years, as this X-ray detector, a portable one that wirelessly transmits and receives image signals and the like to and from the console unit by communication means such as Wi-Fi (Wi-Fi / Wi-Fi Alliance trademark registration). in use.

When such a portable X-ray detection unit is used, X-rays are confirmed by voice or light in order to confirm that the X-ray detection unit designated in the console unit is set correctly. Detectors have been proposed.

Patent Document 1 discloses a radiation image capturing system in which a radiation image detection device selected by a console unit turns on a light emitting unit with a light emission period corresponding to the console unit. In the apparatus described in Patent Document 1, an operator ID of an operator is registered in advance in the console, and the operator ID is transmitted together with selection display information to the selected radiation image detection apparatus. Thus, when the radiological image detection apparatus is taken out from the cradle, the name of the operator who has selected the radiographic image detection apparatus can be notified using sound, vibration, etc., and the radiological image detection apparatus can be used among a plurality of operators. Can be prevented.

Further, in Patent Document 2, among X-ray detectors installed in a radiographing room, a portable cassette is used that gradually increases the sound volume in a selected cassette and gradually decreases the sound volume in a cassette that is not selected. A radiation image detection device is disclosed.

Further, Patent Document 3 discloses an operating state corresponding to designation that the X-ray detector is a desired radiation receiver and a non-state corresponding to designation that the X-ray detector is not a desired radiation receiver. A current state is determined, including an operational state and a non-operational state corresponding to the X-ray detector not being configured to operate with the X-ray base station, and a visual indication of the state of the X-ray detector Discloses a system for adjusting the operation of a wireless X-ray detector.

The music data created by the music generator 26 in the console unit 2 is transmitted to the speaker 11 in the X-ray detector 1 wirelessly.

When performing X-ray imaging in the X-ray imaging apparatus having the above-described configuration, first, an X-ray suitable for X-ray imaging among the plurality of

X-ray detection units

1a, 1b, 1c, 1d, and 1e is selected by the operator. The line detection unit 1 is selected. This selection is performed when the operator inputs the X-ray detection unit 1 selected from the input unit 23 in the console unit 2.

If the X-ray detection unit 1 to be used is selected, the music generation unit 26 in the console unit 2 transmits music data to the speaker 21 on the console unit 2 side, and generates music from the speaker 21 on the console unit 2 side. . An operator in the operation area 102 where the console unit 2 is installed listens to this music. At the same time, the music generation unit 26 is connected to the console unit 2 with respect to the speaker 11 on the X-ray detection unit 1 side via the transmission / reception unit 22 on the console unit 2 side and the transmission / reception unit 12 on the X-ray detection unit 1 side. The same music data as the music data transmitted to the speaker 21 on the side is transmitted, and the same music as the music generated from the speaker 21 on the console unit 2 side is generated from the speaker 11 on the X-ray detection unit 1 side.

Thus, by selecting the X-ray detection unit 1 used by the operator, the same music is generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side. For this reason, the operator uses the X-ray detection unit 1 that generates the same music as the music generated from the speaker 21 on the console unit 2 side among the plurality of

X-ray detection units

1a, 1b, 1c, 1d, and 1e. It is transported from the storage position and mounted on the standing position imaging table 4 or the standing position imaging table 5. Also at this time, music is continuously generated from the selected speaker 11 on the X-ray detection unit 1 side.

When the installation of the X-ray detection unit 1 to the supine imaging table 4 or the standing imaging table 5 is completed, the operator moves from the imaging region 101 to the operation region 102 in order to perform X-ray imaging. Also at this time, the same music as that generated from the speaker 11 on the X-ray detection unit 1 side is generated from the speaker 21 on the console unit 2 side in the operation area 102. For this reason, the operator can confirm that the correct X-ray detection unit 1 has been selected. Then, the operator operates the input unit 23 in the console unit 2 after confirming that the same music is generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side, Perform X-ray imaging.

Here, in this embodiment, music generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side is different for each of the plurality of X-ray imaging rooms A, B, and C. It has become. That is, the music generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side is different in each of the plurality of shooting rooms A, B, and C. For this reason, when the operator selects an appropriate X-ray detector 1 from the plurality of

X-ray detectors

1a, 1b, 1c, 1d, and 1e arranged at the storage position, music is simultaneously received from the plurality of X-ray detectors 1. Even if this occurs, it is possible to easily select an appropriate X-ray detection unit 1 corresponding to each of the X-ray imaging rooms A, B, and C.

Note that the music generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side may be an entire piece of music or a melody that constitutes a part of the music. ) By selecting appropriate music as music generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side, X-ray imaging is performed in the imaging regions 101 in the X-ray imaging rooms A, B, and C. It is possible to relax the subject M receiving the test.

In the above-described embodiment, the same music is generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side. However, these music may not necessarily be the same as long as the operator can recognize the correspondence. The music generated from the speaker 21 on the console unit 2 side and the speaker 11 on the X-ray detection unit 1 side is, for example, music only for playing an instrument, music with lyrics, different instruments but the same melody, the same composer In addition to the same music, the corresponding music, such as the first music and the first half and the second half of the same music, may be used. That is, the “corresponding music” in the present invention is a concept including not only the same music but also music that allows the operator to recognize the correspondence.
