Multi-layer spiral CT scanner

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...

Problems solved by technology

[0004] In order to solve the technical problem that the helical CT scanner in the prior art lacks a targeted scanning and imaging mechanism, the present invention provides a multi-slice helical CT scanner, which adopts the ZIGBEE communication method to obtain the latest standard test chart, and executes the inspection based on the standard test chart. GAMMA adjusts the analysis of the light and dark levels of the processed image to determine whether it is necessary to add a GAMMA correction action based on the look-up table mode; more importantly, it specifically extracts the type of human organ that is currently scanned, and provides a reference for the human body Organ type Select the corresponding number of detectors to adapt to the type of human organ
