An ultrasonic blood vessel detection system and method

Abstract

The invention relates to an ultrasonic blood vessel detection system and method. The method comprises the following steps: (1) performing bi-mode imaging canning and obtaining black-and-white image frames of a black-and-white mode and Doppler image frames of a pulse Doppler mode; (2) acquiring position information of blood vessel walls; (3) acquiring transmitting focus positions under pulse Doppler imaging of the Doppler image frames corresponding to the black-and-white image frames in real time, wherein a processor module performs next-frame pulse Doppler imaging according to the position information of the blood vessel walls and the transmitting focus positions; (4) setting the positions of blood vessels with position information determined as sampling gates and calculating the position information of the sampling gates under pulse Doppler image by a sampling gate calculating module; (5) judging the types of blood vessels at the positions of the sampling gates; (6) labeling the current black-and-white image frames according to the positions of the blood vessels and the information of the types of the blood vessels. The system and the method solve the problem of complicated operation of manual setting of sampling gates, simplify operation of doctors and increase working efficiency.

Description

technical field [0001] The invention relates to an ultrasonic detection vascular system and a method thereof, belonging to the technical field of ultrasonic imaging. Background technique [0002] Hospitals now have more and more needs for blood vessel detection, especially in ultrasound detection, because ultrasound has no radiation hazards such as CT and X-rays, doctors are particularly interested in using ultrasound for inspection or puncture of carotid arteries, heart, epidermis, kidneys, etc. time detection. When a doctor judges a vein or an artery, the doctor generally judges the artery or a vein according to experience or by using some existing auxiliary techniques on some ultrasound equipment. For example, U.S. Patent US60750651 requires the use of a pressure sensor to compress the examiner's limb to completely or partially block the blood flow of the blood vessel away from the compressed limb, so that the temporary increase of the flow velocity through the previousl...

AI Technical Summary

Problems solved by technology

The above two methods either require additional auxiliary equipment, or the method is relatively complicated. Now it is necessary to invent a relatively simple method or system that can automatically determine the artery or vein without adding additional compression equipment.
