Embodiment Construction

[0024] Embodiments of the multi-slice spiral CT scanner of the present invention will be described in detail below.

[0025] Spiral CT generally scans a single part within 5-10 seconds, or completes data collection in a breath-holding state of the patient, which is convenient for the examination of critically ill patients and infant patients, and can be imaged when the contrast agent reaches its peak value, saving the amount of contrast agent . It can improve the detection rate of lesions and the accuracy of CT measurement, eliminate respiratory motion artifacts; avoid missing small lesions, and can be reconstructed at any position or in any direction. It can ensure that the lesion is the center; avoid partial volume effect; spiral CT can reconstruct high-quality three-dimensional images and angiographic images, and obtain simulated endoscopic images in some parts, with CT perspective function.

[0026] In order to overcome the above disadvantages, the present invention build...

Abstract

The invention relates to a multi-layer spiral CT scanner. The scanner comprises a first assembly, a second assembly and a number adjustment device. The first assembly comprises an X-ray bulb tube, a high-voltage generation device, a control device and a power supply device; the power supply device is connected with the X-ray bulb tube, the high-voltage generation device and the control device separately; the second assembly comprises an image storage device, a Bluetooth communication device, a serial communication device and an LCD display device; in the second assembly, the image storage device is connected with the Bluetooth communication device, the serial communication device and the LCD display device separately; the number adjustment device is connected with an organ identification device and used for receiving the reference organ type to determine the detector number corresponding to the reference organ type. By means of the multi-layer spiral CT scanner, the scanning pertinenceof the CT scanner can be improved.

Description

technical field [0001] The invention relates to the field of spiral CT scanning machines, in particular to a multi-slice spiral CT scanning machine. Background technique [0002] In spiral CT, the X-ray tube scans continuously around the human body while the scanning bed automatically enters the bed at a uniform speed. Therefore, the scanning line is spiral on the patient's body surface. Different from conventional CT scans, the helical scans obtain continuous layer information, which is the information of all tissues within the scanning range, so it is also called volume data, which avoids the possibility of missing small lesions due to respiratory movement during tomographic CT scanning disadvantages. According to different detectors, spiral CT can be divided into single-slice spiral CT and multi-slice spiral CT. Due to the adoption of special detectors and new technologies for digital flat panel detectors, the scanning speed is significantly improved, making fast thin-l...
