摘要： APD-based PET modules are provided for use in combined PET/MR imaging. Each module includes a number of independent, optically isolated detectors. Each detector includes an array of scintillator (e.g. LSO) crystals read out by an array of APDs. The modules are positioned in the tunnel of a MR scanner. Simultaneous, artifact-free images can be acquired with the APD-based PET and MR system resulting in a high-resolution and cost-effective integrated PET/MR system.

摘要： A combined positron emission tomography (PET) and computed tomography (CT) detector mounted on a single support on the same gantry of a combined PET and CT scanner. The common detector includes an array of scintillator crystals or pixels with each pixel mated to a photodetector. The photodetector is connected to discrete event circuitry, which provides discrete event information to the combined PET and CT scanner. Also, the photodetector is connected to integrating circuitry, which provides integrated count rate information to the CT scanner when the discrete event information is not adequate. By using a common detector, the registration of the PET image with the CT image is improved, less components are mounted on the gantry, the overall size of the gantry is reduced, resulting in a shorter tunnel and less rotating mass, and CT performance is enhanced by providing means for selecting the energy level of the x-rays to be detected.
摘要翻译：组合的正电子发射断层扫描（PET）和计算机断层摄影（CT）检测器安装在单个支架上，在组合的PET和CT扫描仪的同一台架上。公共检测器包括闪烁体晶体阵列或像素，每个像素与光电检测器配合。光电检测器连接到离散事件电路，其向组合的PET和CT扫描器提供离散事件信息。此外，光电检测器连接到积分电路，当离散事件信息不充分时，该积分电路向CT扫描器提供集成的计数率信息。通过使用共同的检测器，改善了PET图像与CT图像的配准，在台架上安装的部件较少，机架的整体尺寸减小，导致隧道更短，旋转质量更小，CT性能通过提供用于选择要检测的x射线的能级的装置来增强。

摘要： A V-hull boat design having the engine placed forward of the longitudinal centerline offers advantages over traditional boat designs. The engine is placed forward of the longitudinal centerline of the boat and under the walking deck within the passenger cabin such that it does not interfere with the placement of passenger seating within the boat. Placement of the engine in a position forward of the longitudinal centerline of the boat moves the center of gravity of the boat forward compared with traditional I/O, V drives, and direct drives. By placing the engine forward of the longitudinal centerline, in a location that is generally not utilized in the hull of the boat, substantial passenger and cargo room is preserved in the aft half of the boat. Bow rise during acceleration is reduced; ride comfort is improved through chop or waves; and wake performance behind the boat is improved.
