Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a novel CT imager.
Background
In CT, a certain thickness of the layer of the human body is scanned by X-ray beams, the X-rays transmitted through the layer are received by a detector, converted into visible light, converted into electrical signals by photoelectric conversion, converted into digital signals by an analog/digital converter (analog/digital converter), and input into a computer for processing. The image formation is handled as a division of the selected slice into cuboids of the same volume, called voxels (voxels). The information obtained from the scanning is calculated to obtain the X-ray attenuation coefficient or absorption coefficient of each voxel, and then arranged into a matrix, i.e. a digital matrix (digital matrix), which can be stored in a magnetic or optical disk. Each digit in the digital matrix is converted into small blocks with unequal gray scale from black to white, i.e. pixels (pixels), by a digital/analog converter (digital/analog converter), and the small blocks are arranged in a matrix, i.e. a CT image is formed. Therefore, the CT image is a reconstructed image. The X-ray absorption coefficient of each voxel can be calculated by different mathematical methods. The CT works in such a way that according to the different absorption and transmittance of different tissues of the human body to X-rays, an instrument with extremely high sensitivity is used for measuring the human body, then the data obtained by measurement is input into an electronic computer, and after the electronic computer processes the data, the cross section or the three-dimensional image of the part to be detected of the human body can be taken, and the tiny lesion of any part in the human body can be found;
the CT imaging instrument is used for examining the pathological changes of various parts in human body. The CT scanner is used for scanning the cross section of a human body one by one around a certain part of the human body through electronic computer tomography, by utilizing an X-ray beam, a Y-ray, ultrasonic waves and the like which are accurately collimated and a detector with extremely high sensitivity.
