Precise positioning device and method for carotid ultrasound probe

Abstract

The invention belongs to the field of ultrasonic diagnosis, and specifically discloses a precise positioning device and method for a carotid artery ultrasonic probe. The precise positioning mechanism of the device is fixed above the bracket, and is used to detect the position and posture of the probe relative to the head of the subject to be measured. When in use, the probe position measurement auxiliary mechanism is connected with the probe to provide coded marking points. When working, the head of the object to be measured is located under the fine positioning mechanism, and the fine positioning mechanism detects the relative position of the head of the object to be measured and the probe relative to the world. The pose of the coordinate system is used to obtain the pose of the probe relative to the head of the object to be measured. The present invention can ensure that the probe can be quickly and accurately positioned at the initial detection position in the review of carotid atherosclerotic plaque, and the same ultrasonic section can be obtained, thereby reducing the influence of subjective factors of users and making multiple diagnosis results comparable , to fundamentally solve the technical problem that multiple test results cannot be effectively compared.

Description

technical field [0001] The invention belongs to the field of ultrasonic diagnosis, and more particularly relates to a precise positioning device and method for a carotid artery ultrasonic probe. Background technique [0002] Carotid artery ultrasound is the most widely used technique for examining carotid atherosclerosis. In current clinical examinations, doctors manually adjust the position and angle of the ultrasound probe to detect and measure carotid atherosclerotic plaques in patients. The current inspection and measurement methods are highly dependent on the operator and are limited by the physiological limitations of the human brain, human eyes and human hands. During re-examination, it cannot be guaranteed that the probe is in the same position and in the same ultrasound view as in the previous exploration and measurement. Therefore, there is a large error between the two measured plaque size values, and effective comparison cannot be carried out, which seriously re...
