Synchronous examination for quaternary depths: the blood flow information (spectrum and data) of quaternary depths can be examined synchronously at the direction of supersonic emission for one probe in order to improve the efficiency of cerebrovascular disease examination.
2． Digital movie backplayer: it may store and synchronously reappear the original dynamic data of multi-depths and multi-blood vessels (images and voices). The reappeared data can be back-played without time limit. Besides, the parameter can be regulated secondarily and manual calculation & notes can be done on the spectrum at playback state.
3． It has a 2MHz (pulse wave) supersonic probe and a 4MHz (continuous wave) supersonic probe. It may satisfy the examination of intracranial, jugular & peripheral blood vessels.
4． Sufficient examination parameters: At on-line state, it may display the flow rate at systole peak, flow rate at final stage of diastole, average flow rate, the PI index, the RI index and the S/D ratio in real time in two directions of the blood flow frequency spectrum.
5． The conventional examination in clinic is fast & convenient and operation is simple. At on-line state, the increment, blood flow direction, sampling depth, supersonic strength, zero line, measuring scale and scanning speed can be regulated randomly.ii
6． The advanced digital storage technology is used to facilitate doctors to carry on the conventional examination and re-examination of illness cases to the spectrogram.
7． It stores normal parameter values of both sexes of patients in various age groups examined by famous TCD specialists. When the examination is implemented at on-line state, red alert starts if any parameter is beyond the range of normal values.
8.Professional embolus examination: it uses a professional embolus examination subsystem constructed by a multi-depths and M-module to automatically identify thrombus and artifacts so that the embolus storage time is recorded and number of embolus is calculated.
