Automatic breath-holding detection device for CT scanning

Abstract

The invention discloses an automatic breath-holding detection device for CT scanning. The automatic breath-holding detection device comprises a breath-holding detection host, an elastic waistband andtwo tension belts. Two tension sensors and a detection circuit are arranged in the breath-holding detection host; each tension sensor is connected with a tension belt through a tension ring; one end of each tension ring is fixed in the corresponding tension sensor, and the other end of the tension ring is connected to one end of the corresponding tension belt; a B-shaped plastic buckle is arrangedat the other end of the tension belt; one end of the elastic waistband is fixedly arranged on the corresponding B-shaped plastic buckle; each tension sensor is used for converting physical tension borne by the corresponding tension belt to an analog electric signal; and the detection circuit is used for detecting and analyzing the analog electric signal, generating a tension value, outputting thetension value to an LCD display screen for display, and controlling a loudspeaker to make a warning sound when the tension value does not reach a breath-holding threshold. The device can detect the breath-holding condition of a patient under CT scanning, prevent motion artifacts caused by abdominal breathing motion when the patient holds breath, and improve the quality of CT scanning images.

Description

technical field [0001] The invention relates to the field of medical detection equipment, in particular to a breath-hold automatic detection device for CT scanning. Background technique [0002] There is no deep inhalation and breath-holding during the CT scan of the lungs, and the patient's very subtle lesions are easily missed by the CT scan. The patient's breath-holding is not good, and artifacts are prone to occur during chest and abdomen CT scans, resulting in unclear CT images, resulting in incomplete CT scans and misdiagnosis. The main reason is that during the CT scanning process, the patient's respiratory movement produces motion artifacts, which affect the quality of the CT image, resulting in the inability to distinguish the lesion clearly. Therefore, it is necessary to provide a device for monitoring the patient's breath-holding, which is used to detect the patient's breath-holding situation during the CT scanning process, so as to prevent the motion artifacts g...
