Embodiment Construction

[0043] like figure 1 and figure 2 As shown, an ultrasonic transcranial Doppler blood flow analyzer detection system includes: a string type test piece, an ultrasonic power meter and a TCD instrument under test; the string type test piece is used as a test phantom, and the ultrasonic power meter is used for Measure the maximum output sound power value of the TCD instrument under test.

[0044] The range of the ultrasonic power meter is (0-500) mW.

[0045] The string-type test piece is provided with a rectangular groove, which is used to hold the liquid medium as the human body medium; the handle clamping frame is fixed above the rectangular groove, which is used to clamp the probe of the TCD instrument under test, and the string driven under the liquid medium is monitored through the probe The movement of the blood flow is simulated by the movement of the blood flow; a pulley block is set in the rectangular groove, so that the string is coiled on the pulley at a fixed angle...

Abstract

The invention discloses a detection system and a detection method of an ultrasonic transcranial Doppler blood flow analyzer. The system comprises a chord line type test piece, an ultrasonic power meter and a tested TCD. The method comprises the following steps of: (1) setting environment conditions of metering detection; (2) setting technical conditions of the chord line type test piece; and (3) measuring four detection indexes including flow speed, a working distance, a distance gating error and ultrasonic output power. According to the detection system and the detection method, metering characteristics of the ultrasonic transcranial Doppler blood flow analyzer and corresponding metering detection system and method can be provided, and metering indexes of the metering characteristics are provided.

Description

technical field [0001] The invention relates to the technical field of measurement and monitoring, in particular to a detection system and a detection method of an ultrasonic transcranial Doppler blood flow analyzer. Background technique [0002] Ultrasonic transcranial Doppler blood flow analyzer (hereinafter referred to as "TCD instrument") can non-invasively detect the blood flow of the brain base and carotid arteries under physiological and pathological conditions through the acquisition of cranial ultrasound Doppler echo signals Parameters provide valuable information for the diagnosis and treatment of related diseases. [0003] The TCD instrument is generally composed of a host, probe, display, audio monitoring and recording, printing and other parts. The conventional configuration is a 2MHz pulse wave probe and a 4MHz continuous wave probe. Clinically, the TCD instrument measures the blood flow velocity of intracranial blood vessels (such as wilis circle) and common ...
