Abstract

This paper describes a method for forming three-dimensional images of the prostate using transrectal ultrasound. This method extracts three-dimensional images of the prostate from sets of two-dimensional ultrasound images obtained via a special-purpose transrectal ultrasound probe. Each two-dimensional image is segmented and the results used to form a three-dimensional image of the prostate. A method for segmenting two-dimensional images of the prostate based on the Laplacian-of-Gaussian edge operator is described. The three-dimensional imaging method described provides a new, noninvasive method for monitoring gland pathology during radiation therapy.

摘要

本文描述了一种使用经直肠超声形成前列腺三维图像的方法。该方法从通过专用经直肠超声探头获得的二维超声图像集中提取前列腺的三维图像。对每幅二维图像进行分割，并将结果用于形成前列腺的三维图像。文中描述了一种基于高斯拉普拉斯边缘算子分割前列腺二维图像的方法。所描述的三维成像方法为放射治疗期间监测腺体病变提供了一种新的非侵入性方法。
