Description

Head CT scanning positioner

Technical Field

The utility model relates to a head CT scanning locator.

Background

CT examination is a relatively advanced medical imaging examination technique. CT examinations typically include flat scan CT, enhanced CT scan, and scoliography CT.

In CT, an X-ray beam is used to scan a certain thickness of the human body, and a detector receives the X-rays transmitted through the layer, and after the X-rays are converted into visible light, the visible light is converted into an electrical signal by photoelectric conversion, and then the electrical signal is converted into digital signals by an analog/digital converter (analog/digital converter), and the digital signals are inputted into a computer for processing.

CT diagnosis is generally flat scan CT, enhanced CT scan and brain pool contrast CT.

Generally, the scout scan is a cross-sectional scan, which is performed by taking the canthus line as the baseline and continuously scanning upwards or downwards. The contrast agent commonly used for enhancing CT scanning is an iodine contrast agent, 1.5-2.0 ml of iodine contrast agent is used for each kilogram of body weight, and the contrast agent is forbidden for patients with iodine allergy history and heart and kidney failure.

Usually, the cerebral pool radiography CT injects non-ionic contrast agent or gas through lumbar puncture or occipital cisterna puncture to fill the cerebral pool to be examined. When abdominal CT examination is performed, fasting is required before the examination; orally diluted aqueous iodine preparations set the contour of the visceral organs; the patient needs to hold his breath for scanning during the examination.

When CT head scanning is carried out, the patient is nervous, and meanwhile, part of the patients can intermittently twitch the head nerves, so that the head is vibrated, and a good CT effect cannot be obtained.

Based on the problems, a head CT scanning positioner which can be upgraded aiming at a CT bed and has the effect of clamping and fixing the head is designed.
