  • Patent number: 11311254
    Abstract: An acceleration sensor (10) is attached to a collimator (12) and detects an acceleration of the collimator (12), and a speed calculation unit that calculates the speed of the collimator 12 on a basis of the acceleration detected by the acceleration sensor (10). When the speed of the collimator (12) exceeds a setting speed that is set in advance, a lifting or lowering of an arm (13) is stopped by attaching a permanent electromagnet (42) to a stopper plate (43). In addition, a warning message as a warning indication is displayed on a display unit, and a warning sound as a warning indication is generated from a speaker. Accordingly, damage to an apparatus is prevented.

  • Patent number: 11278252
    Abstract: A workstation 5 links an X-ray image conforming to the Dicom standard and exposure dose data prepared by an exposure measurement system 7 with use of information on the imaging date and time of the X-ray image conforming to the Dicom standard and information on the imaging date and time of the exposure dose data prepared by the exposure measurement system 7. This enables the workstation 5 to calculate an exposure dose corresponding to each X-ray image. Also, the workstation 5 calculates an exposure dose corresponding to each X-ray examination on the basis of data on the start time and end time of the examination received from a console part 1. An examination time and an imaging technique at each examination, data including information on a subject, and information indicating an exposure dose corresponding to the examination are configured as one piece of data and displayed on a display part 51 of the workstation 5.

  • Publication number: 20210378613
    Abstract: When a first-stage push-button switch of an operation unit (2) is pressed, an X-ray imaging control unit (72) transmits a signal A for starting voice guidance to a signal output unit (73) for a voice guidance unit as well as a signal B for starting preparation of X-ray imaging to an X-ray tube control unit (71). At this time, when the pushing operation of the push-button switch is performed, the X-ray imaging control unit (72) immediately transmits the signal A for starting the voice guidance to the signal output unit (73) for the voice guidance unit but transmits the signal B for starting the X-ray imaging after a time t1 has elapsed. The time t1 is a time calculated by subtracting a time t3 required for preparing an X-ray tube (42) for performing X-ray imaging from a time t2 required for the voice guidance.

  • Publication number: 20210378614
    Abstract: After an operator presses a practice mode execution start switch displayed on a touch panel liquid crystal display unit in an operation unit (2) or a touch panel liquid crystal display unit in an operation unit (41) to shift an imaging mode to a practice mode, when the operation unit (2) or the operation unit (41) of the imaging unit is operated, the signal from the X-ray imaging control unit (72) is transmitted to the voice guidance output control unit (52) in a voice guidance unit (5) via a signal output unit for a voice guidance unit (73). The voice guidance output control unit (52) in the voice guidance unit (5) transmits a signal for outputting voice guidance to a speaker (51). As a result, the same voice as a voice when performing the serial imaging is output from the speaker (51). Thus, a subject can execute the practice of a breathing method or the like.

  • Patent number: 10765381
    Abstract: A radiation imaging apparatus performs pre-shot imaging while considering the imaging condition on the tomosynthesis imaging which can be performed right thereafter without repeating a positioning of the radiation irradiation unit on the tomosynthesis imaging. The protocol for the per-shot imaging is read out. Reading out the protocol is executed by that the operator of operation unit of the console and the console 1 reads out the protocol for the pre-shot imaging from the radiology department information system along with the patient information. Therefore, the imaging condition of the protocol for the continuously executed tomosynthesis imaging is read out while linking the protocol of the pre-shot imaging.

  • Patent number: 10701790
    Abstract: An X-ray imaging apparatus operates by selecting an appropriate exposure sensitivity corresponding to the X-ray detector to be used. In the apparatus, an exposure sensitivity corresponding to the flat panel detectors used for an X-ray imaging is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit of the console, and the selected exposure sensitivity is displayed on the display unit of the high-voltage unit. An exposure control is executed based on the exposure sensitivity corresponding to the flat panel detectors used for the X-ray imaging, which is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit. The exposure control unit of the high-voltage unit suspends the X-ray irradiation from the X-ray tube when an integrated value of the X-ray detected by the X-ray dose sensor reaches to the setting-value set relative to the selected exposure sensitivity.

  • Patent number: 10555714
    Abstract: Provided is an X-ray imaging apparatus capable of properly performing an automatic exposure control and an appropriately performing X-ray imaging control with a simple configuration. In cases where there exists a plurality of AEC photo pickup fields for automatic exposure, based on the positional information on an X-ray irradiation area and the AEC photo pickup field(s), the presence or absence of AEC photo pickup field(s) where all areas of the sensitive area are not included in the X-ray irradiation area is detected. In cases where there exist one or more AEC photo pickup fields not included in the X-ray irradiation area, the corresponding AEC photo pickup field is set to be unused. As a result, it is possible to appropriately perform an automatic exposure control and/or perform an X-ray imaging control appropriately with a simple structure.

  • Patent number: 10433800
    Abstract: A radiography apparatus is provided in which delays in imaging do not occur due to the influence of preliminary preparation of a radiation detector. The FPD 4 receives a signal from an X-ray tube control unit 6 and then completes preliminary preparation for the detection of radiation during accelerated movement of an X-ray tube 3 or the FPD 4. That is, the accelerated movement of the X-ray tube 3 or the FPD 4 and the preliminary preparation for the detection of radiation are carried out simultaneously. This enables imaging to be started immediately after the start of constant speed movement of the X-ray tube 3 or the FPD 4 without having to wait for constant speed movement thereof to start preliminary preparation of the FPD 4 as in conventional apparatuses. As a result, delays in imaging do not affect the radiation image.

  • Patent number: 10398401
    Abstract: In a radiation tomography imaging device, the imaging range calculation element 35 calculates a possible imaging range of the FPD 5 based on the imaging distance G, the irradiation swing angle ? and the movable range SP of the X-ray tube 3. The operator can preliminarily calculate the possible imaging range of the radiation detection means prior to the X-ray tomography imaging because the imaging distance, the irradiation swing angle, and the movable range SP are all predetermined parameters. The possible imaging range FP of the FPD 5 is the positional range of the FPD 5 in which the X-ray tube 3 can acquire the X-ray tomography image without moving the X-ray tube 3 to the outside of movable range. Therefore, the radiation tomography imaging can start the X-ray tomography by assuredly moving the FPD 5 within the possible imaging range by referring to the preliminarily calculated possible imaging range of the FPD 5.
