S1 ', a frame ultrasound image is obtained in real time.
S2 ', when receiving preset external input signal, execution step S3 '-S5 ' measures biomass；It does not receive
Return step S1 ' when the external input signal.
S3 ', the degree of approximation of present frame ultrasound image and various types of standard sections is calculated (i.e. most according to preset algorithm
Big approximation coefficient), export the matrix being made of approximation coefficient.
S4 ', judge whether maximum approximation coefficient is less than default second threshold, otherwise the return step S1 ' if being less than is executed
S5’。
Wherein, when maximum approximation coefficient is less than second threshold, illustrate present frame ultrasound image and various types of standards
The degree of approximation of section does not comply with expected standard, i.e. the present frame ultrasound image requirement that does not meet measurement biomass, can be with
Present frame is not measured；Since doctor can be observed not export measurement result, thus it is possible to vary operate the hand of ultrasonic probe
Method, until getting the ultrasound image of measurement result；When maximum approximation coefficient is more than or equal to default second threshold, say
The degree of approximation of the standard section of bright present frame ultrasound image and a certain type meets expected standard, can satisfy measurement biology
The requirement of amount.
S5 ', selection present frame ultrasound image, judge the corresponding standard section type of present frame ultrasound image, and starting corresponds to
Image processing program parse present frame ultrasound image, to export the measurement result of at least one biomass；Return step S1.
Specifically, the position of maximum approximation coefficient in a matrix has corresponded to its defined standard section type in matrix,
It is possible thereby to judge which kind closest standard section of present frame ultrasound image；According to the corresponding mark of present frame ultrasound image
Quasi- section type confirms at least one biomass for including in the ultrasound image；It is identified according to corresponding image processing program
The specific measurement position of biomass in present frame ultrasound image, and draw measurement line；Biomass is measured according to measurement line；
The measurement line for exporting the measured value of biomass and being additional on present frame ultrasound image.
S0 ' to S5 ' through the above steps, ultrasonic diagnostic equipment can be automatically performed the biomass measuring in ultrasound image,
Doctor, which only needs to operate ultrasonic probe, (if having preset key, can start ultrasound image standard section at any time with click keys
Extraction and measurement method), i.e., the ultrasound image of measured value and additional measurement line is sustainably got, dynamically recognizes biology
The variation of amount, this technical solution are particularly suitable for needing the checkup item of dynamic observation, such as heartthrob process；When
So, doctor can also operate ultrasonic diagnostic equipment in the case where being satisfied with ultrasound image observing, freeze ultrasound image and obtain one
Section film.
