目前的小动物辐射研究平台(SARRP)在定位用于照射的小软组织靶点或软组织环境中生长的肿瘤模型方面存在不足。因此,需要一种补充x射线CT的成像方法来将软组织靶点的质量中心(COM)定位到1 mm以内。在本文中,我们报告了一种集成的X射线/生物发光成像/断层成像(BLI/BLT)系统的开发,以提供临床前的高分辨率放射治疗系统。通过添加生物发光成像(BLI)系统作为独立系统,该系统可以在锥束计算机断层扫描(CBCT)成像引导下用于研究小动物的辐射效应,该系统也可以对接到SARRP上。该系统集成了两个机器人旋转台和一个额定最大为130kVp的X射线源,并具有小的可变焦斑。高性能和低噪声的CCD摄像机安装在一个不透光的外壳中,以及一个滤光片组件,用于多波长BL成像和层析成像。实现了三镜布置,消除了旋转摄像机获取多个视角的需要。镜面系统被安装在电动舞台上,以0-90度之间的角度捕捉图像(对于独立系统)。完成了摄像机和CBCT的标定。
The current Small Animal Radiation Research Platform (SARRP) is poor for localizing small soft tissue targets for irradiation or tumor models growing in a soft tissue environment. Therefore, an imaging method complementary to x-ray CT is required to localize the soft tissue target’s Center of Mass (CoM) to within 1 mm. In this paper, we report the development of an integrated x-ray/bioluminescence imaging/tomography (BLI/BLT) system to provide a pre-clinical, high resolution irradiation system. This system can be used to study radiation effects in small animals under the conebeam computed tomography (CBCT) imaging guidance by adding the bioluminescence imaging (BLI) system as a standalone system which can also be docked onto the SARRP. The proposed system integrates two robotic rotating stages and an x-ray source rated at maximum 130 kVp and having a small variable focal spot. A high performance and low noise CCD camera mounted in a light-tight housing along with an optical filter assembly is used for multiwavelength BL imaging and tomography. A three-mirror arrangement is implemented to eliminate the need of rotating the CCD camera for acquiring multiple views. The mirror system is attached to a motorized stage to capture images in angles between 0-90o (for the standalone system). Camera and CBCT calibration are accomplished.
