Abstract: Described is a method for segmenting an anatomical part, including identifying a landmark on a contour/surface of a 2D/3D model of the anatomical part in an ultrasound image, assigning a weight to the landmark, identifying different appearance patterns of a region around the landmark based on a previously stored training set; and applying a filter to the different appearance patterns of the region around the landmark in order to identify contours of the anatomical part.

Abstract: Discussed herein is an image processing device and a corresponding method for assessing inflammatory bowel diseases. A plurality of dynamic MRI sequence of images of a bowel that include peristalsis information of the bowel and static MRI image(s) of the bowel that identify at areas of inflammation, stenosis, and increased mural thickness of the bowel are processed. A displacement of the bowel caused by respiration of the patient is conducted on the dynamic MRI sequences by performing a non-rigid registration. A peristaltic activity is determined by performing motion flow analysis on the dynamic sequences of images. A peristaltic activity of the static MRI image(s) based on a weighted sum of two closest dynamic MRI sequences of images is computed and the static image is combined with the closest dynamic MRI sequence of images by performing a multi-modal registration.

Abstract translation: 本文讨论的是用于评估炎症性肠病的图像处理装置和相应的方法。 处理肠道图像的多个动态MRI序列，其包括肠的蠕动信息和肠的静态MRI图像，其在炎症，狭窄和肠壁厚度增加的区域识别。 通过执行非刚性配准，在动态MRI序列上进行由患者的呼吸引起的排便。 通过对图像的动态序列执行运动流分析来确定蠕动活动。 计算基于图像的两个最接近的动态MRI序列的加权和的静态MRI图像的蠕动活动，并且通过执行多模式注册将静态图像与图像的最接近的动态MRI序列组合。
