Problems solved by technology
[0010] The problem to be solved by the present invention is that the current ultrasonic diagnostic instrument manually adjusts the pulse repetition frequency and the baseline position in the corresponding spectrum scale so that the doctor spends a lot of time on this aspect. The Doppler spectrum optimization method and device of the diagnostic instrument enable the system to automatically obtain the current Doppler spectrum envelope and automatically adjust the baseline to the best position of the entire spectrum image accordingly

The invention relates to a Doppler frequency spectrum optimization method and a device for a touch screen ultrasonic diagnostic instrument. The method includes the following steps of a, obtaining Doppler data, calculating a maximum frequency curve fmax and a minimum frequency curve fmin of Doppler frequency spectrum through a pulse repetition frequency (PRF) setting module and transmitting the fmax and the fmin to a controller to judge whether the Doppler frequency spectrum has an aliasing or not; b, if the Doppler frequency spectrum has the aliasing, increasing the PRF through the PRF setting module or adjusting a baseline position through a baseline setting module to overcome the aliasing; c, judging whether the frequency spectrum width of the Doppler frequency spectrum meets a pre-set threshold value or not through the PRF setting module, and if the frequency spectrum width of the Doppler frequency spectrum can not meet the pre-set threshold value, decreasing the PRF under the condition that no aliasing occurs through the PRF setting module; d, judging whether the current Doppler frequency spectrum is required to be overturned or not through the baseline setting module; and e, transmitting a frequency spectrum optimizing result to a display to be correspondingly displayed and output by a Doppler optimizing module through the controller. The Doppler frequency spectrum optimization method and the device for the touch screen ultrasonic diagnostic instrument have the advantages that the operation is convenient, and the display effect is improved.
Description
technical field [0001] The present invention relates to a touch-screen ultrasonic diagnostic instrument and a Doppler spectrum optimization method, in particular to a Doppler spectrum optimization method and device for a touch-screen ultrasonic diagnostic instrument, in particular to a Doppler spectrum automatic optimization method A touch screen ultrasonic diagnostic instrument belongs to the technical field of touch screen ultrasonic diagnostic instruments. Background technique [0002] Doppler blood flow display adds rich and useful blood flow information on the basis of two-dimensional ultrasound, that is, sonogram. Now the ultrasound field has become an indispensable technology. How to obtain effective and high-quality spectral images is particularly important to correctly evaluate Doppler ultrasound findings and avoid misdiagnosis. [0003] In Doppler imaging, the vertical axis of the spectrum is the positive and negative blood flow velocity of the blood flow, and the...
