His information, for example, the frame ultrasound image that ultrasonic diagnostic equipment filters out immediate standard section in the film freezed is tire
The thalamus plane of youngster, can automatic measurement fetus two biomass of biparietal diameter and head circumference, and extrapolate pregnant week, while will be above-mentioned
Information output display.
In step s3, preset algorithm can be intelligent algorithm, in particular by artificial neural network.Rationally setting
Artificial neural network can be carried out for the standard section of each type using a certain number of standard sections ultrasound image
Training is completed after training, to input a frame ultrasound image, that is, can determine whether the degree of approximation of itself and various types of standard sections.
Certainly, preset algorithm is also possible to image characteristics extraction mode, identify in a frame ultrasound image have which/which characteristics of image
And judge which kind of standard section the ultrasound image comprising these characteristics of image corresponds to, approximation coefficient group is not present under this mode
At matrix, but result is reflected directly in success and extracts characteristics of image, successful match standard section.Using other calculations
It is also adoptable means that method, which carries out classification to image, herein without being described in detail.
It, can be (this using correspondence image processing routine for the biomass measuring of different standard sections in step S5
Corresponding relationship can be one-to-one, many-one or multi-to-multi, be determined according to practical application), it is raw on ultrasound image for identification
The boundary of object structure, the shape for confirming biological structure etc. calculate and judge which kind of biological structure it belongs to, which correspondence can measure
Biomass；It identifies after biological structure (the specific measurement position of biomass), line is measured according to the boundary mapping of biological structure, and
According to the measured value of measurement line computation biomass.Image recognition and label, survey calculation, image superposition belong to routine techniques hand
Section, herein without being described in detail.
