    摘要: A thermal treatment system including a heat applying element for generating thermal doses for ablating a target mass in a patient, a controller for controlling thermal dose properties of the heat applying element, an imager for providing preliminary images of the target mass and thermal images during the treatment, and a planner for automatically constructing a treatment plan, comprising a series of treatment sites that are each represented by a set of thermal dose properties. The planner automatically constructs the treatment plan based on input information including one or more of a volume of the target mass, a distance from a skin surface of the patient to the target mass, a set of default thermal dose prediction properties, a set of user specified thermal dose prediction properties, physical properties of the heat applying elements, and images provided by the imager. The default thermal dose prediction properties are preferably based on a type of clinical application and include at least one of thermal dose threshold, thermal dose prediction algorithm, maximum allowed energy for each thermal dose, thermal dose duration for each treatment site, cooling time between thermal doses, and electrical properties for the heat applying element. The user specified thermal dose prediction properties preferably include at least one or more of overrides for any default thermal dose prediction properties, treatment site grid density; and thermal dose prediction properties not specified as default thermal dose prediction properties from the group comprised of thermal dose threshold, thermal dose prediction algorithm, maximum allowed energy for each thermal dose, thermal dose duration for each treatment site cooling time between thermal doses, and electrical properties for the heat applying element.

    摘要: A method for generating realistic images using discrete representations employs a discrete voxel based representation of the scene within a three-dimensional (3-D) Cubic Frame Buffer of infinitesimal voxels. Each voxel stores information corresponding to the attributes of that portion of the scene. Numerous sight rays are traversed through the Cubic Frame Buffer. When a non-transparent infinitesimal voxel is encountered by a traversing sight ray, a hit is recognized. The attributes of that portion of the object that is encountered are then used for generating secondary rays. Depending upon the number and characteristics of the secondary rays that are generated, an appropriate representation of the scene can be generated from any viewing direction.

    摘要: The method and apparatus of the present invention provides real-time reorientation of stored data and real-time visualization for high resolution volumetric datasets from an arbitrary designed viewing direction. The apparatus includes a modularized memory having a plurality of memory modules wherein each memory module includes a plurality of memory storage units capable of storing voxel data therein. The apparatus also includes reorientation unit coupled to each of the plurality of memory modules for simultaneously receiving voxel data from memory storage units of each memory module. The reorientation unit simultaneously provides the voxel data corresponding to a first memory storage unit to a second memory storage unit according to a desired viewing direction. The apparatus further includes fetching unit coupled to each of the plurality of memory modules for simultaneously retrieving voxel data from the plurality of memory modules according to the desired viewing direction and projection unit coupled to the fetching unit. The fetching unit provides the projection unit with voxel data retrieved from the plurality of memory modules. The voxel data retrieved by each projection ray includes a plurality of voxel attributes indicative of the characteristics of the object. The projection unit generates a projection value corresponding to the cumulation of voxel attributes. The projection value is indicative of the opaqueness of the aggregate of voxel attributes for each projection ray. The apparatus includes display unit coupled to the projection unit for displaying the projection value.
