Shape feature-based ultrasonic image bladder volume measuring method and device

Abstract

The invention discloses a shape feature-based ultrasonic image bladder volume measuring method and device. The shape feature-based ultrasonic image bladder volume measuring method comprises the following steps: acquiring a two-dimensional bladder ultrasonic image; recognizing the shape of a bladder according to the two-dimensional bladder ultrasonic image; measuring the volume of the bladder according to the shape of the bladder. The shape feature-based ultrasonic image bladder volume measuring device comprises a two-dimensional bladder ultrasonic image acqusition unit for acquiring the two-dimensional bladder ultrasonic image, a bladder shape recognition unit for recognizing the shape of a bladder according to the two-dimensional bladder ultrasonic image and a bladder volume measuring unit for measuring the volume of the bladder according to the shape of the bladder. According to the shape feature-based ultrasonic image bladder volume measuring method and device, shape difference shown in different states by the bladder in clinical application is combined, the shape of the bladder is used as priori knowledge, the volume of the bladder is automatically calculated according to the current shape of the bladder, and the accuracy for measuring the volume of the bladder is improved.

Description

technical field [0001] The invention relates to a bladder volume testing method and device, in particular to a shape feature-based ultrasonic image bladder volume measuring method and device. Background technique [0002] Bladder volume is an important parameter for clinical application in emergency department, anesthesiology department, urology department, ICU and other departments, reflecting the urine volume in the bladder. 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. The bladder is a very important organ of the human body, and it has the following clinical manifestations: 1) About the shape: it is an inverted "triangular pyramid" shape in the empty state, and an "ellipsoid" shape in the filled state; 2) The bladder can be viewed approximately 3) There are no other substances in the bladder except urine, so the bladder volume is the amount of urin...

But this is a method of trauma to the human body. Not only does X-ray irradiation have a certain degree of damage to the human body, but the contrast medium makes the user face the risk of allergic discomfort

[0004] 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. At present, this method requires manual collection of multi-directional bladder B-ultrasound images. and familiarity affect the image quality, resulting in measurement errors; secondly, measuring the bladder diameter in bladder B-ultrasound images in all directions inevitably increases the workload of the user, and the measurement takes a long time

This bladder measurement method is not combined with the actual clinical situation, ignoring the difference in the shape of the bladder in different states, resulting in inaccurate measurement results
