Head supporting device for CT perfusion examination

Abstract

The invention discloses a head supporting device for CT perfusion examination, and relates to the technical field of CT equipment. The device comprises a CT scanning assembly used for CT perfusion scanning, a head supporting mechanism used for adjusting the head supporting angle and a head supporting plate used for supporting the head; the CT scanning assembly comprises a CT scanner and a bed frame body, wherein a bed body used for installing the head supporting mechanism is movably arranged in the bed frame body; the head supporting mechanism comprises a mounting base plate arranged at the bottom of the bed body, an electric push rod is arranged at the top of the mounting base plate, and a control block is fixedly arranged at the output end of the electric push rod. The head supporting assembly and the head supporting plate are arranged, the head of a patient is supported through the head supporting plate, the height and angle of the head supporting plate are adjusted in cooperation with the two inclined supporting rods and the top plate, so that the head of the patient is kept upturned, positioning of the head supporting plate is completed through the electric push rod, the operation process is simple and rapid, angle adjustment is accurate, and wide application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of CT equipment, in particular to a head support device for CT perfusion inspection. Background technique [0002] CT perfusion imaging is different from dynamic scanning. It performs continuous CT scanning on the region of interest during the rapid intravenous bolus injection of contrast agent, so as to obtain the time-density curve of the region of interest, and use different mathematical models to calculate various parameters. Therefore, it can more effectively and quantitatively reflect the change of local tissue blood perfusion. This is a cutting-edge technology in the field of CT application, which is of great significance for clarifying the blood supply of lesions. used widely. [0003] At present, in the CT cerebral perfusion examination, the patient will take the supine position, so that the head is lifted close to the chest to ensure the scanning efficiency.

Problems solved by technology

[0003] At present, in the CT cerebral perfusion examination, the patient will take the supine position, so that the head is lifted close to the chest to ensure the scanning efficiency. Generally, the patient controls the head lifting independently. The examination process takes between 40 and 90 seconds, or even longer Time, patients are prone to fatigue, unable to maintain, affecting the inspection data, especially for some elderly patients, compared with young patients, the number of elderly patients is more, sometimes need to repeat the inspection, seriously affecting the efficiency of the inspection, to the medical staff and patients have caused serious distress
