Multifunctional Radiography, Tomography and Fluoroscopy Device
The invention relates to radiographic equipment comprising a height-adjustable board (1), a C-shaped arch (3), disposed transversally to the greater dimension (D) of the board (1), said board being housed within the internal space defined between the two free extremities (3, 3) of the arch (3). The arch (3) is slidingly mounted on a column (4) by means of a connecting element (5) in such a way that as the arch (3) rotates around an imaginary rotational axis (13) it causes the connecting element (5) to slide or roll throughout the extension of the arch (3). It further comprises a rail (12) extending parallel to the greater dimension of the board (1), on which the column (4) rests. The arch (3) features at its lower extremity (3) an x-ray receiver (6) and at its upper extremity (3) an x-ray emission assembly (7).

High-energy ray detector and tomographic image acquisition apparatus
A high-energy ray detector includes a detection unit in a vacuum container. The detection unit includes a first electron multiplier, a second electron multiplier, and an electron collector. Each of the first electron multiplier and the second electron multiplier has one or more MCPs each configured to emit electrons by interaction with an incident high-energy ray (-ray, X-ray (in particular hard X-ray), or neutron ray), and multiply and output the electrons. The electron collector is transmissive for the high-energy ray. The electron collector is configured to collect the electrons multiplied and output from each of the first electron multiplier and the second electron multiplier, and output an electric pulse signal.
Auger plate for x-ray phase contrast imaging and detectors comprising the Auger plates
An Auger plate for converting line emission x-ray photons into cascades of Auger electrons that form transient electric charges and for channeling the transient electric charges to an optical imager for conversion of the transient electric charges into a radiographic signal, the Auger plate including an array of Auger sensors which are graphite fibers coated with CsI or Gd coatings. The coatings are configured and arranged to bind the graphite fibers together and to convert the line emission x-ray photons into the cascades of Auger electrons to form the transient electric charges. The graphite fibers are configured and arranged to channel the transient electric charges toward the optical imager. Also, a detector including the Auger plate, a conductive film and an optical imager and a method for preparing the Auger plate.
Techniques for producing an image of radioactive emissions using a compton camera and compton lines
Techniques for imaging radioactive emission in a target volume include receiving data indicating a set of one or more known emission energies associated with a high energy particle source and determining a Compton line for each emission energy in the set. A Compton camera collects location and deposited energy from an interaction associated with a single source event from a target volume of a subject. For the single source event, an earliest deposited energy, E.sub.1, and first scattering angle, .sub.1, and a cone of possible locations for the source event are determined. A particular location for the high energy particle source within the target volume without including the single source event, if E.sub.1 is not within a predetermined interval of the Compton line for at least one of known emission energies. A solution is presented on a display device.
