摘要： In one aspect, a method of displaying data is provided. The method comprises obtaining projection data of an object by exposing an object to radiation at a plurality of view angles and detecting at least some of the radiation exiting the object to form the projection data, operating a computer to reconstruct the projection data at a reconstruction resolution to form image data comprising a plurality of voxels representing locations within the object, each of the plurality of voxels being assigned an associated intensity indicative of a density of the subject matter at the respective location, determining a maximum resolution for display, above which variation in intensity between adjacent voxels is not supported by information in the projection data, the maximum resolution being less than the reconstruction resolution, and displaying the image data at or below the maximum resolution.
摘要翻译：在一个方面，提供了一种显示数据的方法。该方法包括通过将物体暴露于多个视角处的辐射来获得物体的投影数据，并检测离开物体的至少一些辐射以形成投影数据，操作计算机以重建分辨率重建投影数据以形成包括表示所述对象内的位置的多个体素的图像数据，所述多个体素中的每一个被分配指示所述相应位置处的所述对象物的密度的相关强度，确定用于显示的最大分辨率，投影数据中的信息不支持相邻体素之间的强度，最大分辨率小于重建分辨率，并以最大分辨率或低于最大分辨率显示图像数据。

摘要： In one aspect, A method of imaging an object of interest positioned in an exposure area is provided. The method comprises obtaining projection data of the object by providing radiation to the exposure area and detecting at least some of the radiation exiting the object to form the projection data, performing a first reconstruction of the projection data to form at least one bootstrap image, obtaining first data based on information provided by the at least one bootstrap image, and performing a second reconstruction of the projection data based, at least in part, on the first data to form at least one second image.
摘要翻译：在一个方面，提供了一种对位于曝光区域中的感兴趣对象进行成像的方法。该方法包括通过向曝光区域提供辐射并检测离开物体的辐射中的至少一些以形成投影数据来获得物体的投影数据，执行投影数据的第一重构以形成至少一个自举图像，基于由所述至少一个自举图像提供的信息的第一数据，以及至少部分地基于所述第一数据执行所述投影数据的第二重构以形成至少一个第二图像。

摘要： In one aspect, a method of obtaining projection data of an object from a plurality of view angles with respect to the object is provided. The method comprises acts of providing radiation, at each of the plurality of view angles, to an exposure area in which the object is positioned, controlling a radiation energy of the radiation provided at each of the plurality of view angles such that the respective radiation energy is different for at least two of the plurality of view angles, and detecting at least some of the radiation passing through the exposure area at each of the plurality of view angles to obtain the projection data.

摘要： A method and apparatus for imaging an object including the steps of projecting radiation from a radiation source through an object and moving the radiation source through multiple imaging positions relative to the object without stopping movement of the radiation source Movement is accomplished while projecting radiation at more than one of the imagining positions with the source having a source velocity for at least one imaging position that is different from a source velocity for a second imaging position Radiation transmitted through the object is also detected Radiation may be projected while moving the radiation source through the multiple imaging positions In addition, the velocity at which the radiation source is moved through a select imaging position may be related to a resolution desired for data collection at the select imaging position The velocity of the radiation source may be varied within a select imaging position.
