Problems solved by technology

[0009] However, according to the above-mentioned conventional technology, the high-voltage capacitor is alternately discharged and charged for each shooting, and shooting cannot be performed while the high-voltage capacitor is being charged, so high-speed continuous shooting cannot be performed.
Therefore, in the above-mentioned prior art, it is not possible to perform perspective photography, which is based on the premise of high-speed continuous photography.

Deformed example 1

[0111] In the above-mentioned first embodiment, an example in which the same number of batteries 30 - 1 to 30 -N are connected to the plurality of boosting units 23 - 1 to 23 -N has been described, but a plurality of boosting units 23 may be -1~23-N is connected with a battery structure.

[0112] In this case, the switching control of the boosting units 23-1 to 23-N itself is the same as the above-mentioned example, but when charging the discharged boosting unit, any one of the boosting units uses the power from the above-mentioned one battery. Electricity to charge. This modified example has the effect of simplifying the system configuration because it is possible to charge all the boosting units with one battery.

[0113] In addition, in the case where the voltage boosting units 23 - 1 to 23 -N are connected to different batteries as a condition, except that the number of batteries and the number of voltage boosting units are the same number as in the above-mentioned first ...

Deformed example 2

[0116] In the first embodiment described above, the charging state of the boosting unit to be discharged must be a fully charged state. The reason for this is to perform X-ray photography by irradiating X-rays of the same X-ray quality multiple times in a short time.

[0117] However, in X-ray photography, it is known that the so-called energy subtraction is used to separate images of soft tissue and bone by taking two X-ray images under different X-ray conditions and obtaining the difference in energy distribution. The photography of photography (photography).

[0118] In order to perform this energy subtraction imaging, it is necessary to continuously irradiate X-rays with different ray qualities in a short period of time as described above, but in the above-mentioned first embodiment, since control is performed to irradiate X-rays with the same ray quality multiple times, It is difficult to perform the energy subtraction photography described above.

[0119] Therefore, ac...

no. 2 Embodiment approach

[0137] Below, refer to Figure 15 The X-ray imaging apparatus 200 of the second embodiment will be described.

[0138] In addition, in the X-ray imaging apparatus 200 of this embodiment, the only difference from the X-ray imaging apparatus 1 of the first embodiment is that the thermoelectric conversion unit 14, the battery switching unit 60 are provided, and the system control The processing content of part 6 is different in this point. Therefore, below, it demonstrates centering on a different part.

[0139] Such as Figure 15As shown, the X-ray imaging apparatus 200 has a thermoelectric conversion unit 14 that converts thermal energy generated when a voltage is supplied to the X-ray tube 3 into electrical energy, and a battery switching unit 60 . The thermoelectric conversion unit 14 has a function of recovering thermal energy generated when a DC high voltage is supplied to the X-ray tube 3 and converting it into electrical energy (DC power).

Abstract

The invention provides an ultrasonic diagnosis device. The X-ray equipment related to the embodiment is configured from a plurality of pressure rising units, a switching unit, and a switching control unit. The plurality of pressure rising units are connected to the battery unit and generate direct current voltage. The switching unit switches over the plurality of pressure rising units and supplies direct current voltage to the X-ray generating unit. The switching control unit transmits switching instructions to the switching unit for switching over the pressure rising unit after receiving voltage supply instructions with respect to the X-ray generating unit until said voltage supply instructions terminate. The switching control unit controls discharging of the condenser inside the pressure rising unit switched over by the switching instructions and the control of commencing charging of the condenser inside the pressure rising unit following termination of discharging.

Description

[0001] (related application) [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2011-281636 with a filing date of December 22, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] An embodiment of the present invention relates to an X-ray imaging device. Background technique [0004] An X-ray imaging device is a device that detects X-rays transmitted through a subject to image the inside of the subject. As this X-ray imaging device, for example, it is known to mount equipment for X-ray imaging including an X-ray tube for X-ray irradiation on a movable cart, and to supply power necessary for X-ray imaging and traveling of the cart. The battery of the so-called X-ray imaging device for rounds. [0005] The X-ray radiographic apparatus for outpatient visits is configured to have a power adjustment unit that converts a battery into an AC voltage having a predetermined voltage and fre...
