Ultrasonic detecting system and method for intracranial blood flow

Abstract

The invention provides an ultrasonic detecting system for intracranial blood flow. The system comprises a probe, a transmitting and receiving control module, a time gain wavelength amplifier, a wave velocity synthesis module and a signal processing module, wherein the probe comprises a plurality of ultrasonic transducer array elements, and the size of the probe is in accordance with the size of a skull; the transmitting and receiving control module controls the ultrasonic transducer array elements of the probe to transmit ultrasonic pulses into the patient skull, receive ultrasonic echo waves generated by the ultrasonic pulses, and transform the ultrasonic echo waves into electrical signals; the time gain wavelength amplifier is used for amplifying the electrical signals generated by the ultrasonic transducer array elements; the wave velocity synthesis module is used for processing the electrical signals which are amplified by the time gain wavelength amplifier and forming synthesized signals; the signal processing module is used for processing the synthesized signals generated by the wave velocity synthesis module and generating processing results. The invention further provides an ultrasonic detecting method for the intracranial blood flow, and the method enables an operator to easily capture Doppler frequency spectrum and enables intracranial blood flow detecting to be more straightforward.

Description

technical field [0001] The invention relates to the field of blood flow detection, in particular to an ultrasonic intracranial blood flow detection system and method. Background technique [0002] Intracranial blood vessel inspection plays a vital role in analyzing and judging people's physical conditions, but the sound permeability of the skull directly affects the success of the detection. In particular, the inspection of intracranial blood vessels generally detects intracranial blood vessels by placing the probe at the fenestration or the foramen magnum at the back of the neck, and allowing the sound beam to pass through the fenestration or the foramen magnum. [0003] As a non-invasive, economical, simple, and reproducible inspection method, transcranial Doppler blood flow analyzer TCD has been widely used in clinical practice, and has the advantage of real-time dynamic evaluation of hemodynamic changes. However, the transcranial Doppler analyzer generally uses a single...

Problems solved by technology

[0005] However, the current CDFI probe is generally large in size, and the surface of the probe cannot fit well with the skull, thus affecting the imaging effect

In addition, the penetration of CDFI probes is lower than that of TCD probes, which affects the accuracy of intracranial vessel detection
