Method and device for measuring bladder volume through ultrasound images

Abstract

The invention discloses a deformable model-based method and device for measuring bladder volume through ultrasound images. The method for measuring the bladder volume through ultrasound images includes that acquiring n ultrasound images of a bladder; orderly arraying the n ultrasound images of the bladder according to the acquisition sequence, and constructing three-dimensional data of the bladder according to space information of the bladder; using a deformable model corresponding to the current form of the bladder to carry out three-dimensional image segmentation on the three-dimensional data of the bladder to obtain the bladder region; calculating the volume of the bladder region. The deformable model-based method and device for measuring the bladder volume through ultrasound images fully consider the shape difference of the bladder under different states, enable the bladder volume measurement result to be closer to the clinical manifestation of the bladder, enable the bladder volume measurement precision to be improved, and provide more precise reference data for diagnosing and treating bladder diseases.

Description

Technical field [0001] The invention relates to a method and device for testing bladder volume, in particular to a method and device for measuring bladder volume using ultrasound images. Background technique [0002] Bladder volume is an important parameter for clinical applications in emergency departments, anesthesiology, urology, ICU and other departments, reflecting the amount of urine in the bladder. For the urinary system, the measurement results of the residual urine volume and the filled urine volume of the bladder are often used as an important basis for diagnosing cases. The bladder is a very important organ of the human body. It has the following clinical manifestations: 1) Regarding the shape: an inverted "triangular pyramid" shape in an empty state, and an "ellipsoid" shape in a full state; 2) The bladder can be seen approximately Symmetrical; 3) There is no other substance in the bladder except urine, so the bladder volume is the amount of urine in the bladder; if ...

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 o
