摘要： A method for processing medical images for use in the detection and diagnosis of disease comprises classifying regions of interest within the medical images based on a hierarchy of anatomical models and signal models of signal information of an image acquisition device used to acquire the medical images. The anatomical models are derived to be representative of anatomical information indicative of a given disease. A computer-aided system for use in the diagnosis and detection of disease comprises an image acquisition device for acquiring a plurality of image data sets and a processor adapted to process the image data sets. The processor is adapted to classify selected tissue types within the image data sets based on a hierarchy of signal and anatomical models and the processor is further adapted to differentiate anatomical context of the classified tissue types for use in the diagnosis and detection of disease.

摘要： A system for displaying sets of surface cubes with gradient vertex vectors first employs a pointer table constructed to order the surface cubes so as to generally cause a row by row and layer by layer ordering during model creation. During display, a viewpoint is selected and a scan controller causes cubes to be displayed according to this order of the pointer table. A test backprojection of cubes to image plane is performed to determine which pixels will be impinged by the cubes. For pixels which have not been updated, or pixels which have been updated by a less superficial cube than the current cube, projection rays are created through the center of impinged pixels in a direction opposite that of the backprojection. An intersection point of the ray with a surface within a current cube is determined. The data value and gradient vectors for the current cube are interpolated at this intersection point. These interpolated vector and value are then rendered to produce and image with less distortion and with less processing complexity.

摘要： A system for display of interfaces within a block of raw data values comprises a model building portion groups data points into a cubes, receives a threshold and identifies cubes which a vertex data values which straddle the threshold. These are surface cubes. Gradient vectors for each vertex of each cube are determined by comparing the change in data values in three dimensions in a neighborhood around each vertex. The surface cubes and their associated gradient vectors are stored as a cube/vector model. his model may be tessellated and then displayed by conventional CAD/CAM workstations. A second display system is shown which employs a modified "Dividing Cubes" method to subdivide the cubes, interpolate each to a center point and associated vector, then backprojected to produce perspective.

摘要： An interactive surgery planning and display system mixes live video of external surfaces of the patient with interactive computer generated models of internal anatomy obtained from medical diagnostic imaging data of the patient. The computer images and the live video are coordinated and displayed to a surgeon in real-time during surgery allowing the surgeon to view internal and external structures and the relation between them simultaneously, and adjust his surgery accordingly. In an alternative embodiment, a normal anatomical model is also displayed as a guide in reconstructive surgery. Another embodiment employs three-dimensional viewing.

摘要： A group visualization system allowing users of a group, either at a local site or a remote site to view images personalized to each users specific needs. Each user of the team interactively selects personalize viewing parameters, such as portions of the model to be displayed and the angle to view the model. Each user may select an overlay map to be superimposed on the model and displayed in the same manner which the model is displayed. A user who is an electrical engineer may select a voltage overlay, which a mechanical engineer may select a stress/strain overlay of the same model. Each user may select the parameters specified by another user or users, either at the local site or a remote sites, to see what they are viewing. Each user has access to a pointer which allows each user to specify a location which a symbol is superimposed and is visible to selected users. This results in a tool allowing users of a group at various sites to act as a team interact with each other.

摘要： A mechanism for improving connectivity processing of computer axial tomography and magnetic resonance images by a fast, stack independent, iterative method first designates a pixel of an object material of interest in an image as a seed pixel. The mechanism then performs connectivity processing by starting at the seed pixel and evaluating the next forward direct neighbor pixel to determine if it is within the object material of interest. If the direct neighbor pixel is within the object, the direct neighbor pixel is marked as a new seed pixel and the connectivity mechanism evaluates the next forward direct neighbor pixel, continuing in a left-to-right and top-to-bottom fashion. Once forward processing of all pixels is complete, and if at least one pixel has been identified as a new seed pixel, the connectivity mechanism evaluates, in a backward progression, unevaluated pixel within the image, beginning at the lower right-most pixel in the image and proceeding through the pixels in a right-to-left, bottom-to-top fashion.
摘要翻译：用于通过快速，不依赖于堆叠的迭代方法改进计算机轴向断层摄影和磁共振图像的连接处理的机制首先将图像中感兴趣的物体材料的像素指定为种子像素。该机制然后通过从种子像素开始执行连接处理，并评估下一个前向直接相邻像素，以确定它是否在感兴趣的对象材料内。如果直接邻居像素在对象内，则直接相邻像素被标记为新的种子像素，并且连接机制评估下一个向前直接相邻像素，以从左到右和从上到下的方式继续。一旦所有像素的正向处理完成，并且如果至少一个像素被识别为新的种子像素，则连接机制在向后进展中评估图像内的未评估像素，从图像中的最右边的像素开始图像，并以从右到左，从底到顶的方式贯穿像素。

摘要： A patient surface is registered with a model surface based on curvature by acquiring patient range data and determining the curvature of the patient surface based on the range data. The patient surface is generated and shaded based on the curvature. A model surface is generated from image data and processed to determine the curvature of the model surface. The model surface is shaded to represent the curvature. The shaded patient surface and the shaded model surface are aligned in registration with each other by manipulating the patient surface and/or the model surface until the curvature features coincide.
