超楕円を用いた前立腺輪郭の形状抽出・モデリング手法に関する研究

抄録

In this report we propose a novel method for shape extraction and modeling of MRI prostate contours. Transperineal targeted biopsy with real-time fusion image of multiparametric magnetic resonance image and transrectal ultrasound image have a problem that the diagnostic ability is uneven in accordance with the skill of the medical professionals. To cope with these problems, we propose a method, which is not affected by diagnostic ability, to extract prostate contour utilizing deformable superellipse models. The characteristic of oue method is to implement the region division function for the deformable superellips models to enhance the expressiveness to handle the left and right asymmetry of the prostate contours. Experimental results show our proposing method is effectiveness.
