Carotid artery three-dimensional image building device

Abstract

The invention discloses a carotid artery three-dimensional image building device. The carotid artery three-dimensional image building device comprises a handheld scanning auxiliary device, an ultrasonic probe, an image frame capture module and a processing system. The ultrasonic probe is fixed to the handheld scanning auxiliary device; the handheld scanning auxiliary device drives the ultrasonic probe to move to enable the ultrasonic probe to be capable of continuously and stably collecting carotid artery two-dimensional slice images at different positions at a first speed; the ultrasonic probe is connected with the image frame capture module through a first data connecting line; the image frame capture module collects the carotid artery two-dimensional slice images transmitted by the ultrasonic probe at a second speed and transmits the collected carotid artery two-dimensional slice images to the processing system through a second data connecting line; the processing system extracts the carotid artery two-dimensional slice images collected by the image frame capture module at a third speed; and the carotid artery two-dimensional slice images are built into carotid artery three-dimensional images. By means of the carotid artery three-dimensional image building device, the carotid artery three-dimensional images used for auxiliary diagnosis can be accurately built.

Description

technical field [0001] The invention relates to the technical field of image acquisition and processing, in particular to a carotid three-dimensional image construction device. Background technique [0002] Stroke is the most common serious neurological disease worldwide and the third leading cause of death among adults in North America. According to statistics in the United States, the direct and indirect cost of stroke reaches 2.8 billion US dollars per year. Clearly, stroke poses a severe morbidity, mortality, and economic burden. Better methods and treatments for identifying stroke patients at high risk would have enormous implications. [0003] Approximately 85% of strokes are ischemic, most of which are due to intracranial arterial thromboembolism. Atherosclerosis at the carotid bifurcation is the main source of emboli, which come from platelet aggregation (white thrombus) or the shedding of small emboli from atherosclerotic plaques. Improving the diagnosis of high...

Problems solved by technology

However, simple components of the local area within a vessel relative to blood flow velocity provide only indirect information on the severity of stenosis, but no direct information on the plaque, such as area, volume, and rate of stenosis.

Thus, limited in assessing arterial wall characteristics
