Abstract

This locking unit for restricting withdrawal of a stored object restricts the withdrawal of the stored object stored in a storage slot of an apparatus, the locking unit comprising: an advancing and retreating unit installed to advance and retreat in a direction in which the stored object is inserted into and withdrawn from the storage slot; a rotating unit rotatably coupled to one end of the advancing and retreating unit so as to be rotatable toward an open portion of the storage slot; and a stopper unit for restricting retreating when the advancing and retreating unit advances. When one side of the rotating unit is rotated toward the storage slot, the advancing and retreating unit advances; when the rotating unit is rotated to be in contact with the edge of the stored object stored in the storage slot, the stopper unit restricts the retreating of the advancing and retreat unit so as to restrict the withdrawal of the stored object as the rotating unit is fixed without rotating in the opposite direction; and when the restriction of the retreating of the advancing and retreat unit by the stopper unit is released, the rotating unit can rotate in the opposite direction and the restriction of withdrawal of the stored object is released. The locking unit can be applied to restrict the withdrawal of a detector stored in a storage unit of a mobile X-ray device.

Abstract

A high frequency X-ray generator includes an anode voltage generator, a cathode voltage generator and a X-ray tube. The anode voltage generator is configured to generate a first high voltage. The cathode voltage generator is configured to generate a second high voltage having a same waveform as the first high voltage. The second high voltage has a different phase by 180 degrees compared to the first high voltage. The X-ray tube is configured to generate a X-ray by the first high voltage and the second high voltage. The first high voltage is applied through an anode terminal. The second high voltage is applied through a cathode terminal.

Abstract

The present invention relates an X-ray generator system performing wireless communication between an X-ray generator and an X-ray detector installed in a digital X-ray image capturing apparatus. The X-ray generator system comprises: an X-ray generator including a generator body for generating X-rays, and a first communication module which is connected to the generator body and is capable of performing wireless communication with an external device; and an X-ray detector including an X-ray detector body generating digital image data by capturing X-rays penetrating a subject, and a second communication module which is connected to the X-ray detector body and is capable of performing wireless communication with the first communication module. The X-ray generator wirelessly transmits a preliminary signal to the X-ray detector, and the X-ray detector, which has received the preliminary signal, removes charges remaining in the X-ray detector body and thereafter wirelessly transmits a preparation completion signal to the X-ray generator. The X-ray generator wirelessly receives the preparation completion signal from the X-ray detector, and then irradiates X-rays. According to the present invention, it is possible to achieve enhanced quality of the captured image and to also maximize convenience in the maintenance and repair of the system.
