摘要： Embodiments of the systems and methods of this disclosure utilize different positions, or poses, of a target object to collect images that can result in high-resolution volumetric models of the target object. In one embodiment, the object poses define a lateral position and an axial position (also “angular orientation”) of the target object relative to components of an imaging system, e.g., the source of the x-ray beam. The imaging system captures an image of the target object in the object poses. Further processing of the image data that relates to the images generates a volumetric model of the target object at higher resolution, or with fewer artifacts, as compared to similar volumetric models that arise from conventional scanning of these large parts.
摘要翻译：本公开的系统和方法的实施例利用目标对象的不同位置或姿势来收集可导致目标对象的高分辨率体积模型的图像。在一个实施例中，对象姿势定义目标对象相对于成像系统的成分（例如，X射线束的源）的横向位置和轴向位置（也称为“角度定向”）。成像系统在对象姿势中捕获目标对象的图像。与这些大部件的常规扫描产生的类似的体积模型相比，与图像相关的图像数据的进一步处理以更高的分辨率产生目标对象的体积模型，或者具有较少的伪影。

摘要： Among other things, one or more techniques and/or systems for correcting projection data representative of an object under examination to account for drift in a radiation system are provided. System drift is measured by performing a drift calibration on the radiation system. During the drift calibration, a temperature of the radiation system is measured and one or more calibration tables, such as an air table and/or offset table, are corrected based upon the measured temperature to derive a theoretical projection (e.g., indicative of measurements that are expected to be acquired from the radiation system during the drift calibration). The theoretical projection is compared to an actual projection acquired during the drift calibration to measure a degree of drift. Based upon the measured degree of drift, one or more correction factors are determined to correct and/or otherwise adjust for system drift in a projection respective of the object.
