Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography. Similar techniques are used in airport security (where "body scanners" generally use backscatter X-ray). To create an image in Conventional Radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object. A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography. In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around the subject which itself moves through the conical X-ray beam produced. Any given point within the subject is crossed from many directions by many different beams at different times. Information regarding attenuation of these beams is collated and subjected to computation to generate two dimensional images in three planes (axial, coronal, and sagittal) which can be further processed to produce a three dimensional image.

Systems and methods for a direct fusion heat exchanger and neutron generation
PCT designated stageWO2026049780A3Cosmonautic vehiclesNuclear energy generationHigh fluxReactor design
A direct fusion heat exchanger technology allows for the efficient transfer of fusion plasma heat energy to a working fluid for aerospace propulsion and other applications. Aspects of this disclosure also enable the generation of high neutron fluxes for applications like medical isotope production, materials testing, and neutron radiography. The use of a thin-film beam window array allows charged particles from a fusion plasma or accelerator to pass through and directly interact and heat the working fluid or fusion target. The thin-film beam window array offers advantages in efficiency, compactness, and safety compared to traditional fusion reactor designs. The technology also addresses the limitations of existing neutron sources by providing a simpler, cheaper, and more efficient method for generating high neutron fluxes.
