Patent number: 12138101Abstract: Provided is an X-ray image apparatus. The X-ray imaging apparatus include an imaging body and a control circuit. The image body acquires X-ray image data of an object and includes an X-ray generation device and an X-ray sensing device. The X-ray generating device and the X-ray sensing device are disposed to face each other with the object in between. The control circuit reconfigures an X-ray image of the object based on the X-ray image data, acquire size information of the object, rotate the X-ray generation device and the X-ray sensing device about a rotation axis between the X-ray generation device and the X-ray sensing device, and move the object along a direction of the rotation axis with respect to the X-ray generation device and the X-ray sensing device when acquiring the X-ray image data.Type: GrantFiled: August 31, 2021Date of Patent: November 12, 2024Assignees: VATECH Co., Ltd., VATECH EWOO Holdings Co., Ltd.Inventors: Tae Hee Han, Yong Joo Yang, Sung Hwan Lim

Patent number: 10799198Abstract: Disclosed is an X-ray image radiographing apparatus being economical by using a small width sensor, occupying less space, and providing an X-ray CT image and an X-ray panoramic image without distortion and with high accuracy. An X-ray image radiographing apparatus according the present invention includes a rotation supporter rotating based on a rotation shaft; a generating unit including an X-ray generator radiating an X-ray beam; a sensing unit including a small width sensor moving in a width direction thereof; and a controller changing a rotation speed of the rotation supporter or a frame rate of the sensing unit to compensate changes in magnification ratio according to a distance change between an area of interest of the subject and the small width sensor when performing an X-ray image radiographing sequence obtaining a number of CT images by rotating the rotation supporter.Type: GrantFiled: October 26, 2016Date of Patent: October 13, 2020Assignees: VATECH Co., Ltd., VATECH EWOO Holdings Co., Ltd.Inventors: Byung-Jun Ahn, Sang-Og Na, Yong-Joo Yang, Sung-Il Choi, Dae-Ki Hong
