摘要： A method and apparatus for reconstruction of a region of interest for an object is provided. The reconstruction of the object may be based on chords which may fill a part, all, or more than all of the region of interest. Using chords for reconstruction may allow for reducing data acquired and/or processing for reconstructing a substantially exact image of the ROI. Moreover, various methodologies may be used in reconstructing the image, such as backprojection-filtration, and modified filtration backprojection.

摘要： A method and apparatus for reconstruction of a region of interest (ROI) for an object using an imaging system is provided. The imaging system may substantially exactly reconstruct the ROI with a straight line trajectory. In the straight line trajectory, the ROI is not bounded or encircled by the actual trajectory of the source (e.g., no chords that are composed from two points on the source trajectory intersect or fill the ROI to be imaged). However, the ROI may be substantially reconstructed by using “virtual” chords to reconstruct the ROI. The virtual chords are such that no point on the trajectory is included in the virtual chord (such as one that is parallel to the straight line trajectory). These virtual chords may intersect and fill the ROI, thus enabling substantially exact reconstruction. Further, in reconstructing the image, the straight line trajectory may be assumed to be infinite in length.
摘要翻译：提供了一种用于使用成像系统重建用于对象的感兴趣区域（ROI）的方法和装置。成像系统可以用直线轨迹基本上精确地重建ROI。在直线轨迹中，ROI不受源的实际轨迹的限制或环绕（例如，由源轨迹上的两个点组成的和弦不相交或填充要被成像的ROI）。然而，可以通过使用“虚拟”和弦来重建ROI来实质地重建ROI。虚拟和弦使虚拟和弦中不包含轨迹上的点（例如平行于直线轨迹的点）。这些虚拟和弦可以相交并填充ROI，从而实现基本精确的重建。此外，在重建图像时，可以认为直线轨迹的长度是无限大的。

摘要： In some embodiments, an image-guided radiotherapy apparatus and method is provided in which a radiotherapy radiation source and a gamma ray photon imaging device are positioned with respect to a patient area so that a patient can be treated by a beam emitted from the radiotherapy apparatus and can have images taken by the gamma ray photon imaging device. Radiotherapy treatment and imaging can be performed substantially simultaneously and/or can be performed without moving the patient in some embodiments. The gamma ray photon imaging device can be coupled and movable with respect to any part of a building structure, can be located on a portable frame movable to and from the radiotherapy radiation source and patient, or can take other forms. In some embodiments, the gamma ray photon imaging device can be used for imaging in connection with other types of medical interventions.

摘要： Various radiation-attenuating agents can be administered within a patient body cavity in combination with therapeutic irradiation of the patient body cavity, such as during radiographic diagnostic imaging procedures, to attenuate the radiation incident on certain portions of the patient body cavity believed to be susceptible to harm from the incident radiation. A variety of methods are provided, including methods for detecting clinical conditions such as pulmonary embolus in a pregnant woman while mitigating uterine radiation exposure.
