1. A system for use in generating a volumetric reconstruction of an object, said system comprising: an X-ray source configured to generate an X-ray beam, said X-ray source positioned on a first side of the object; at least one detector capable of measuring X-rays scattered from the X-ray beam, said at least one detector positioned on the first side of the object in a pre-determined orientation with respect to said X-ray source; and a computing device programmed to: define a point cloud including a plurality of points associated with a three-dimensional (3D) space, wherein at least a portion of the object is within the 3D space; instruct said X-ray source to sweep the X-ray beam across the plurality of points; receive, from said at least one detector, measurement data for each point of the plurality of points, the measurement data representative of scattered X-rays associated with the X-ray beam and measured by said at least one detector; assign a contrast value to each point in a subset of the plurality of points, the subset determined by defining a volume of points included within a geometry defined by an intersection of a field of view of the at least one detector and a penetrating path of the X-ray beam through the object; and generate a volumetric image of the object using a projection of the measurement data for the plurality of points into the object.
