Method and system for automatically measuring bladder volume of ultrasonic image

Abstract

The invention relates to a method and system for automatically measuring the bladder volume of an ultrasonic image. The method for measuring the bladder volume comprises the following steps of: acquiring an ultrasonic image; acquiring an ultrasonic bladder image through ultrasonic scanning; preprocessing the ultrasonic image; preprocessing the acquired ultrasonic bladder image; acquiring a bladder pixel contour line through the gray level difference between the ultrasonic bladder image and peripheral ultrasonic non-bladder images; selecting radial line measured values: analyzing the acquired bladder pixel contour line and selecting a first radial line measured value and a second radial line measured value; and the measuring the bladder volume according to the selected first radial line measured value and the selected second radial line measured value. According to the method for measuring the bladder volume of the ultrasonic image, the measuring result is more accurate, and the measuring precision is improved; meanwhile the repeated and dried works of a user can be reduced, and the efficiency of an ultrasonic diagnosis system is improved; and the method disclosed by the invention is more convenient and rapid to use.

Description

technical field [0001] The invention relates to a method and device for automatic image measurement, in particular to a method and device for automatic measurement of bladder volume based on ultrasonic images. Background technique [0002] With the development of electronic technology, B-mode ultrasound system is more and more used in medicine due to its non-invasive advantages, and it is also widely used in urological examination; It is also an important reference value for the treatment of certain urinary diseases; therefore, the measurement of bladder volume is also an essential item in the application of urological ultrasound. [0003] At present, the bladder volume measurement of two-dimensional ultrasound images is mainly based on manual measurement; the radial line of the bladder is manually positioned and drawn by moving the trackball, and then the volume of the bladder is calculated by the corresponding formula; however, in manual measurement During the process, th...

[0003] At present, the bladder volume measurement of two-dimensional ultrasound images is mainly based on manual measurement; the radial line of the bladder is manually positioned and drawn by moving the trackball, and then the volume of the bladder is calculated by the corresponding formula; however, in manual measurement During the process, the user's operation technique and proficiency will affect the positioning of the target object, so manual errors will inevitably occur, and repetitive work is required, which is boring and time-consuming. When measuring bladder volume, it is often due to Manual error makes the measurement result inaccurate and affects the doctor's judgment. Therefore, a new measurement method is needed to reduce the error and improve the accuracy of the measurement, so as to avoid the doctor's misjudgment
