Abstract

The invention discloses a micro vessel examination and identification system and method. The system comprises a multifrequency ultrasound angiography probe, a multiplexer, a T / R conversion switch, a user-controlled input system, an adjustable pulse transmitter, an echo receiver, a time gain compensation unit, an AD converter, a beam synthesis unit, a signal processing unit, an image processing unit, a blood vessel examination and identification system and a display system. According to the micro vessel examination and recognition system, the high frequency ultrasound probe is adopted for detecting microvessels, the multifrequency detection probe and an ultra-fast composite Doppler imaging technology are adopted, very low velocity microvessel detection can be achieved without a contrast agent, different working frequencies and working modes are selected according to different detection areas and different degrees of imaging resolution / speed sensitivity, and the functions of dynamic Doppler rate review and three-dimensional reconstruction of vascular microstructures are achieved; doctors can observe and evaluate repeatedly conveniently, and doctors are helped to diagnose.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a micro blood vessel inspection and identification system and method. Background technique [0002] The existing structural imaging detection of human blood vessels is mainly realized by ultrasonic perfusion contrast, and the blood flow velocity is mostly realized by ultrasonic Doppler technology. However, due to the influence of ultrasonic frequency, the blood flow velocity detected by it is generally unable to detect low-speed capillaries. Clinical studies have shown that the benign and malignant nature of tumors and lymph nodes can be judged by the display of small blood flow, and the effect of tumor treatment can be evaluated; the stability of the plaque can be judged by the new blood vessels in the carotid plaque, that is, the risk of stroke can be judged. However, at present, the monitoring of neovascularization of carotid plaques mainly relies on contrast-enhanced ultrasoun...
