Ultrasound Image Organ Volume Automated Measurement Fetal Bladder Urinary Bladder Phantom Experiment Bubble Filling Method Boundary Detection 容積計測

项目摘要

The purpose of this study is to measure the volume of the target organ accurately and automatically from ultrasound images. In order to measure the volume accurately, it is necessary to determine the boundary of the target organ beforehand. It is, however, difficult to detect the organ boundary satisfactorily, because the ultrasound image quality is seriously deteriorative. Therefore, we developed the method for measuring the volume of the target organ accurately and automatically using the newly proposed Bubble Filling Method. As a result of applying this method to agar gel phantom data, it was possible to measure the volume accurately and automatically.In this research period, we measured 50 fetal bladder volumes to verify the method's effectiveness. Data acquision was as follows : the angle (parallel) and the speed of the probe applied to the mothers' abdomen were fixed during the scanning. Then we applied this method to the data and measured the volume. As a result, it was possible to measure the volume accuraterly and automatically.Finally, we proposed the method for measuring the volume of urinary bladders accurately and easily from ultrasound images. A set of two-dimensional cross-section images and a vertical-section image are acquired by parallel scanning and then the urine bladder volume is measured accurately without special hardware. As a result of applying this method to experimental data and clinical data, it was possible to measure the volume of the urinary bladder.In addition, we constructed computer-set that is able to handle and save enormous clinical data.

本研究的目的是从超声图像中准确、自动地测量靶器官的体积。为了准确地测量体积，需要预先确定目标器官的边界。然而，由于超声图像质量严重恶化，难以令人满意地检测器官边界。因此，我们开发了一种新的气泡填充法，用于精确和自动测量靶器官的体积。将该方法应用于琼脂凝胶体模数据，可以实现准确、自动地测量胎儿膀胱体积，本研究期间对50例胎儿膀胱体积进行了测量，验证了该方法的有效性。数据采集如下：在扫描过程中固定探头施加到母亲腹部的角度（平行）和速度。然后我们将此方法应用于数据并测量体积。最后，提出了一种从超声图像中准确、简便地测量膀胱体积的方法。通过平行扫描获得一组二维横截面图像和一组垂直截面图像，然后在不需要特殊硬件的情况下精确测量膀胱体积。将此方法应用于实验数据和临床数据，使膀胱体积的测量成为可能，并建立了一套能处理和保存大量临床数据的计算机系统。
