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

Embodiment Construction
[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. It should be noted that in the drawings or descriptions, similar or identical elements use the same reference numerals.
[0036] The embodiment of the present invention proposes an ultrasonic intracranial blood flow detection system and method. By using a small-sized low-frequency phased array probe, it can well solve the problem that the color Doppler blood flow imaging probe fits the skull, and improve The penetration of color Doppler blood flow imaging and spectral imaging improves the imaging effect. The invention first processes the ultrasonic echo signal to form a composite signal, and then performs multiple processing on the composite signal, which improves the accuracy of ...

The invention provides an ultrasonic intracranial blood flow detection system, comprising: a probe, including a plurality of ultrasonic transducer array elements, the size of the probe fits the skull; a transmitting and receiving control module, controlling a plurality of ultrasonic transducer arrays of the probe The unit transmits ultrasonic pulses to the patient's brain and receives the ultrasonic echoes generated by the ultrasonic pulses, and converts the ultrasonic echoes into electrical signals; the time gain wavelength amplifier is used to amplify the electrical signals generated by the ultrasonic transducer array element The wave velocity synthesis module is used to process the electrical signal amplified by the time gain wavelength amplifier to form a composite signal; the signal processing module is used to process the composite signal generated by the wave velocity synthesis module and generate a processing result; The invention also provides an ultrasonic intracranial blood flow detection method, which makes it easier for the operator to capture the Doppler spectrum and makes the intracranial blood flow detection more intuitive and clear.
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...
