System and method for monitoring breath holding of patient by means of infrared distance measurement

Abstract

The invention discloses a system and method for monitoring breath holding of a patient by means of infrared distance measurement. The system comprises an infrared distance measurement mainframe, a jitter transfer device and a computer terminal; the jitter transfer device comprises a light reflection board, an abdominal protective sleeve and a communicating mechanism; the infrared distance measurement mainframe comprises a mainframe shell, a mainframe circuit board, an infrared emitting end, an infrared receiving end and a serial interface; the infrared emitting end comprises an infrared emitting tube and a convex lens; the infrared receiving end comprises an infrared receiving tube light filter; the mainframe circuit board comprises an infrared emitting circuit, an infrared receiving circuit, an amplifying circuit, an A / D converter, a single chip microcomputer, an RS232 to RS485 conversion circuit and an interface circuit; and the computer terminal is connected with the infrared distance measurement mainframe through the serial interface, and breath holding monitoring app software used for detecting a breath holding state of the patient is installed on the computer terminal. According to the system and method for monitoring breath holding of the patient by means of infrared distance measurement, the breath holding situation of the patient during CT scanning can be monitored bymeans of infrared distance measurement, the quality of CT scanning images is improved, and the accuracy of a CT diagnosis result is improved.

Description

technical field [0001] The invention relates to the field of medical detection equipment, in particular to a patient breath-hold monitoring system and method through infrared distance measurement. Background technique [0002] If the patient does not take a deep breath and hold his breath during the CT scan of the chest and lungs, it is easy to miss some subtle diseases. At the same time, poor breath-holding is prone to artifacts, blurred images, or incomplete scans, which can lead to misdiagnosis. The reason for these phenomena is that the respiratory movement of the patient produces motion artifacts during the CT scan, which affects the quality of CT imaging, resulting in the inability to clearly identify the location of the lesion. Ordinary chest and lung examinations generally require breathing coordination twice, one for scouting and one for formal tomography. In order to avoid the increase of radiation dose caused by re-scanning and re-scanning, the amount of each in...
