Embodiment 1

[0054] Such as figure 1 As shown, embodiment 1 of the present invention provides fetal head circumference automatic measurement method, comprises the following steps:

[0055] S1. Obtain an ultrasound image of the fetal head;

[0056] S2. Perform preprocessing on the ultrasound image, divide the bone area and non-skeleton area in the ultrasound image, and obtain a binary result image;

[0057] S3. Thinning the binary result image divided into the bone area and the non-skeleton area to obtain a bone thinning image;

[0058] S4. Fit the curve in the bone thinning image to obtain a curve function, and calculate the curve feature of the curve according to the curve function;

[0059] S5. Screening each of the curves according to the preset characteristic conditions of the head curve to obtain the head curve;

[0060] S6. Calculate the fetal head circumference length according to the head curve.

[0061]This embodiment provides a method for automatic measurement of fetal head c...

Embodiment 2

[0117] Embodiment 2 of the present invention provides an automatic measurement device for fetal head circumference, including a processor and a memory, and a computer program is stored on the memory. When the computer program is executed by the processor, the fetal head circumference provided by Embodiment 1 is realized. automatic measurement method.

[0118] The fetal head circumference automatic measurement device provided by the embodiment of the present invention is used to realize the fetal head circumference automatic measurement method, therefore, the technical effect possessed by the fetal head circumference automatic measurement method is also possessed by the fetal head circumference automatic measurement device, which will not be repeated here repeat.

Abstract

The invention relates to an automatic fetal head circumference measuring method. The method comprises the following steps: acquiring an ultrasonic image of a fetal head; preprocessing the ultrasonic image, and dividing a skeleton region and a non-skeleton region in the ultrasonic image to obtain a binary result image; performing refinement processing on the binary result image divided into the skeleton area and the non-skeleton area to obtain a skeleton refined image; fitting a curve in the skeletal refinement image to obtain a curve function, and calculating curve characteristics of the curve according to the curve function; screening the curves according to preset head curve characteristic conditions to obtain head curves; and calculating the fetal head circumference length according to the head curve. The invention can realize automatic, accurate and efficient measurement of the fetal head circumference.

Description

technical field [0001] The invention relates to the technical field of ultrasonic image measurement, in particular to an automatic measurement method, device and computer storage medium for fetal head circumference. Background technique [0002] Ultrasound imaging has the advantages of no radiation, real-time, and low price, so it is widely used in daily clinical examinations. In obstetric examinations, accurate fetal biometrics play a vital role in determining the gestational age of the fetus, estimating the fetal weight, and assessing the status of fetal growth and development. Commonly used biometric parameters for fetuses include head circumference (AC), head-rump length (CRL), biparietal diameter (BPD), occipitofrontal diameter (OFD), femoral length (FL), and abdominal circumference (AC). The measurement of fetal head circumference is an important parameter for evaluating fetal growth and development. [0003] At present, manual measurement is usually used clinically ...
