Embodiment Construction

[0018] Refer to the following figure 1 , figure 2 and Figure 6 The computer stereotaxic device and method for X-ray targeting target of the present invention are described.

[0019] A device that detects the position of the target in the patient’s body and can be adjusted so that the focal point of the focused therapeutic energy coincides with the target: it includes a C-shaped arm 4 that can swing around the horizontal axis Y, and an image intensifier 2 is installed at one end With the camera 1, the other end is equipped with an X-ray tube 8 emitting X-rays, and the image input surface 3 of the image intensifier 2 is irradiated by X-rays, so that the central axis of the X-ray beam emitted by the X-ray tube 8 runs through the image input surface 3 The intersection point of the two coordinate axes is perpendicular to the image input surface 3, and the central axis of the X-ray beam is perpendicular to the horizontal axis Y around which the C-arm swings; an electric transmis...

Abstract

A computerized 3D locating device and method for X ray and target object is characterized by that the X-Y planar image generated by using X ray to radiate the target object (such as calculus) in human body and the 3D position data from position sensor and mathematically analyzed by computer and the calculated result can control the electric driver to move for automatically coinciding said target object with the focus point of therapeutic equipment. Its advantages are high speed, and less damage of X ray to people.

Description

technical field [0001] The invention relates to an X-ray positioning device for a target and a method thereof. Background technique [0002] In current clinical applications, most of the positioning of X-ray targets depends on the observation of images by medical personnel and the manual pressing of buttons to operate the transmission device to complete the positioning operation. The targets mentioned here are stones, tumors, etc. that can be observed by irradiating the human body with X-rays. For example, the X-ray positioning extracorporeal lithotripsy machine is mainly composed of a swing-arm single-beam X-ray device, an XTV television system, a shock wave generating treatment device, a special hospital bed, and an electric transmission device with three-dimensional freedom. The image intensifier and camera of the XTV TV system are installed at one end of the C-shaped arm that can swing around the horizontal axis of the swing-arm single-beam X-ray device, and the X-ray t...
