Embodiment 1

[0098] Aiming at the problems that the existing automatic bladder volume measurement method based on image grayscale information is easily limited by the grayscale range when detecting the bladder contour, and is prone to errors and inaccurate measurement results when delineating the boundary, this embodiment proposes a method based on ultrasound The bladder volume calculation method and system of RF (ie radio frequency) data, by using the original RF data and the method of secondary correction, the bladder volume calculation result is more accurate, the accuracy of the bladder volume calculation is improved, and the ultrasound diagnosis is also improved. The accuracy rate is more convenient and faster to use.

[0099] Such as image 3 with 4 As shown, the specific steps of the bladder volume calculation method of the present embodiment are:

[0100] (1) Perform ultrasonic scanning, and receive ultrasonic echo data through the probe.

[0101] (2) Obtain bladder ultrasound R...

Abstract

The invention discloses a method and system for calculating the bladder volume. The method includes the steps that bladder echo radio frequency data is obtained; an initial bladder contour line is obtained according to the amplitude difference of the bladder echo radio frequency data and the boundary continuity of the bladder; the initial bladder contour line is finely adjusted through a key point moving method, and a final bladder contour line is obtained; the bladder volume is calculated according to the final bladder contour line. The bladder contour is detected through original data, namely the bladder echo radio frequency data, limitation of the gray scale range and the influence of the boundary gray scale change are avoided, detection accuracy is improved, the bladder contour can be more accurately detected, and the precision of the calculated result of the bladder volume is improved. The contour line is better attached to an actual boundary by finely adjusting key points on the bladder contour line, the boundary can be accurately described, and then the more precise calculated result of the bladder volume is obtained. The method and system can be widely applied to the field of ultrasonic image processing.

Description

technical field [0001] The invention relates to the field of ultrasonic image processing, in particular to a method and system for calculating bladder volume. Background technique [0002] Bladder volume reflects the urine volume in the bladder, and is one of the important parameters for clinical application in departments such as emergency department, anesthesiology department, urology department and ICU. For the urinary system, the measurement results of residual urine volume and full urine volume of the bladder are often used as an important basis for diagnosis of cases. [0003] With the continuous advancement of technology, ultrasonic non-invasive detection has been developed in clinical applications. The use of ultrasonic non-invasive methods can accurately monitor and measure the volume of the bladder. The calculation formula to calculate the volume of the bladder. [0004] At present, the automatic measurement method of bladder volume has the following defects or d...
