Abstract: A radiological imaging device that includes a source that emits radiation that passes through at least part of a patient, the radiation defining a central axis of propagation; and a receiving device that receives the radiation and is arranged on the opposite side of the patient with respect to the source. The receiving device includes a first detector to detect radiation when performing at least one of tomography and fluoroscopy, a second detector to detect radiation when performing at least one of radiography and tomography; and a movement apparatus arranged to displace the first and second detectors with respect to the source. The movement apparatus provides a first active configuration in which the radiation hits the first detector and a second active configuration in which the radiation hits the second detector.

Abstract: Systems and methods to manufacture a collimator include deposition of a first layer of material in a first pattern, the first pattern comprising a first plurality of substantially parallel lines oriented in a first direction, and deposition of a second layer of material in a second pattern directly upon the first layer of material, the second pattern comprising a second plurality of substantially parallel lines oriented in a second direction different from the first direction. An area bounded by a first pair of the first plurality of substantially parallel lines and a second pair of the second plurality of substantially parallel lines intersecting the first pair defines a septum of the collimator.

Abstract: A computer-implemented method of reducing scatter in an X-ray projection image of an object comprises: generating an initial X-ray projection image with an imaging beam and an X-ray detector; based on a first position in a detector array of the X-ray detector, selecting a first kernel for convolution of a first portion of the initial projection image, wherein the first position corresponds to the first portion of the initial projection image; based on a second position in the detector array of the X-ray detector, selecting a second kernel for convolution of a second portion of the initial projection image, wherein the second position corresponds to the second portion of the initial projection image; convolving the first portion with the first kernel and the second portion with the second kernel to generate a scatter component of the initial X-ray projection image; and generating a corrected X-ray projection image by removing the scatter component from the initial X-ray projection image.
