Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an ultrasonic Doppler signal detection system and a control method. Background technique [0002] Ultrasonic Doppler signal detection system is a non-invasive cerebrovascular disease detection method that uses the ultrasonic Doppler effect to detect the hemodynamics and physiological parameters of the main artery at the skull base through the weak part of the skull. It is based on the use of the ultrasonic Doppler effect It is a cerebral blood flow detection technology developed on the basis of applying computer technology to clinical medicine. TCD (transcranial Doppler, transcranial Doppler ultrasound) provides hemodynamic parameters that cannot be measured by imaging techniques such as MRI (Magnetic Resonance Imaging, magnetic resonance imaging), DSA (Digital subtraction angiography, digital subtraction angiography). One of the development directions of TCD is the rese...

Problems solved by technology

Portable portable TCDs refitted from notebooks and made by special mold opening are similar to bedside monitors. These two portable TCDs are only structural changes. They are still composed of TCD detection circuits and INTEL X86 computer boards running WIMDOWS operating systems. Composition, the power consumption is not low enough, and the volume is not small enough, which is not conducive to carrying when doctors make rounds, especially when doctors need to bring multiple devices

At the same time, the existing equipment cannot provide editing and display functions, which is very inconvenient for teaching new doctors or explaining to patients
