    • A multiple x-ray energy level imaging system includes a scanning x-ray beam and two detector design having a first low x-ray energy sensitive detector and a second high x-ray energy sensitive detector. The low x-ray energy detector is placed next to or in front of the high x-ray energy detector. The low energy sensitive detector has small stopping power for x-rays. The lower energy x-rays are absorbed and converted into electrical signals while the majority of the higher energy x-rays pass through undetected. The high energy sensitive detector has a large stopping power for x-rays as well as it having a filter placed between it and the object to absorb the lower energy x-rays. In a second embodiment; a single energy sensitive detector is provided which provides an output signal proportional to the amount of energy in each individual x-ray it absorbed. It can then have an electronic threshold or thresholds set to select two or more energy ranges for the images. By having multiple detectors located at different positions, a dual energy laminography system is possible.
    • 多个x射线能级成像系统包括扫描x射线束和具有第一低x射线能量敏感检测器和第二高x射线能量敏感检测器的两个检测器设计。 低X射线能量检测器放置在高X射线能量检测器旁边或前面。 低能量敏感检测器对于X射线具有较小的停止功率。 较低能量的X射线被吸收并转换为电信号,而大部分较高能量的X射线通过未被检测到。 高能量敏感检测器对于X射线具有大的阻挡力,并且其具有放置在其与物体之间的过滤器以吸收较低能量的X射线。 在第二实施例中; 提供单个能量敏感检测器,其提供与其吸收的每个单独X射线中的能量的量成比例的输出信号。 然后可以设置电子阈值或阈值来选择图像的两个或多个能量范围。 通过具有位于不同位置的多个检测器,双能量层析系统是可能的。

    • In a camera or similar radiation sensitive device comprising a pixilated scintillation layer, a light guide and an array of position sensitive photomultiplier tubes, wherein there exists so-called dead space between adjacent photomultiplier tubes the improvement comprising a two part light guide comprising a first planar light spreading layer or portion having a first surface that addresses the scintillation layer and optically coupled thereto at a second surface that addresses the photomultiplier tubes, a second layer or portion comprising an array of trapezoidal light collectors defining gaps that span said dead space and are individually optically coupled to individual position sensitive photomultiplier tubes. According to a preferred embodiment, coupling of the trapezoidal light collectors to the position sensitive photomultiplier tubes is accomplished using an optical grease having about the same refractive index as the material of construction of the two part light guide.

    • A novel functional imaging system for use in the imaging of unrestrained and non-anesthetized small animals or other subjects and a method for acquiring such images and further registering them with anatomical X-ray images previously or subsequently acquired. The apparatus comprises a combination of an IR laser profilometry system and gamma, PET and/or SPECT, imaging system, all mounted on a rotating gantry, that permits simultaneous acquisition of positional and orientational information and functional images of an unrestrained subject that are registered, i.e. integrated, using image processing software to produce a functional image of the subject without the use of restraints or anesthesia. The functional image thus obtained can be registered with a previously or subsequently obtained X-ray CT image of the subject. The use of the system described herein permits functional imaging of a subject in an unrestrained/non-anesthetized condition thereby reducing the stress on the subject and eliminating any potential interference with the functional testing that such stress might induce.
    • 用于无限制和非麻醉的小动物或其他受试者的成像中的新型功能成像系统以及用于获取这些图像并进一步将它们与先前或随后获得的解剖X射线图像对准的方法。 该装置包括IR激光轮廓测量系统和全部安装在旋转台架上的伽马,PET和/或SPECT成像系统的组合,其允许同时获取被登记的无限制对象的位置和定向信息和功能图像, 即集成的,使用图像处理软件来产生受试者的功能图像而不使用约束或麻醉。 这样获得的功能图像可以与先前或随后获得的受试者的X射线CT图像对齐。 本文描述的系统的使用允许受试者在无限制/非麻醉状态下进行功能成像,从而减少受试者的压力并消除对这种应激可能诱发的功能测试的任何潜在干扰。
