摘要： A medical imaging system having a patient support apparatus is provided. The medical imaging system includes a framework portion; a first set of at least one panel removably mounted to and supported by the framework portion and for supporting a patient during a first imaging study by the medical imaging system; and a second set of at least one panel removably mounted to and supported by the framework portion after removal of the first set of at least one panel from the framework portion. The second set of at least one panel replaces the first set of at least one panel and supports the patient during a second imaging study by the medical imaging system.

摘要： A medical imaging system locates tumors in tissue surrounding an anatomical portion of the human body subject to investigation for primary lesions. The imaging system comprises a single-photon limited angle tomographic imaging device to provide a first emission image including tissue surrounding the anatomical portion. In combination with the single photon limited angle tomographic imaging device, a digital x-ray device provides an x-ray transmission image of the anatomical portion and tissue thereabout. A third component of the imaging system is a single-photon nuclear imaging device for tomographic image acquisition and reconstruction to produce a second emission image of the anatomical portion and tissue previously viewed by the digital radiography device. Registration of the first emission image, the transmission image and the second emission leads to selection of two- and three-dimensional image sets of the anatomical portion and tissue surrounding the anatomical portion.

摘要： An inverse collimator detector for nuclear medicine imaging applications is provided. The inverse collimator detector includes an inverse collimator wherein high density, high atomic number collimator material is placed in the location where the conventional collimator has no material, and no material is placed where the conventional collimator has high density, high atomic number collimator material. The inverse collimator detector of the present invention allows significantly higher detection efficiency for incident photons while providing distance information and maintaining high resolution for isolated, small sources of radioactivity associated with molecular imaging agents.

摘要： The present invention relates to an apparatus for nuclear medicine imaging in which the imaging platform is attached directly to the detectors for nuclear imaging to allow for minimal constant distance between the detector(s) and the object to be imaged. As the detector moves around the object to be imaged to capture different angular views of the object, the imaging platform is rotated in a compensatory manner to maintain a its long axis perpendicular to gravity during movement of the detector. An advantage of this configuration over prior systems is the ability to obtain multiple angular projections while the distance between the detector and the object being imaged is maintained at a minimum, but the danger of detector-object collision is minimized and the necessity for orbital path calibration to preserve precision of detector movement and distance is eliminated.
摘要翻译：本发明涉及一种用于核医学成像的装置，其中成像平台直接连接到用于核成像的检测器，以允许检测器和待成像对象之间的最小恒定距离。当检测器围绕要成像的物体移动以捕获物体的不同角度视图时，成像平台以补偿的方式旋转，以在检测器移动期间保持其长轴垂直于重力。与现有系统相比，该配置的优点是在检测器和被成像对象之间的距离保持最小的同时获得多个角度投影的能力，但检测器 - 物体碰撞的危险被最小化，并且轨道路径校准的必要性以保持检测器运动的精度，消除距离。
