An X-ray imaging apparatus includes a table, an imager configured to capture a plurality of X-ray images, a rotating mechanism, a moving mechanism, and an image processor. The image processor is configured to generate a long image by performing processing of varying magnifications of the plurality of X-ray images based on an amount of relative movement of the table and the imager and splicing the plurality of X-ray images when imaging is performed at a plurality of imaging positions in a state in which an optical axis of X-rays radiated from an X-ray irradiator is inclined with respect to the table.

A portable barium test apparatus is used to perform Modified Barium Swallow Studies (MBSS) on patients in different locations, such as the home of the patient or a care facility. The apparatus includes a hand truck, a U-shaped support, a height-adjusting track, a support carriage, an X-ray generator, and an image-capturing device. The hand truck allows the medical staff to transport the apparatus to the desired location to perform the procedure. The U-shaped support maintains the X-ray generator and the image-capturing device at the desired arrangement to perform the procedure. The height-adjusting track enables the repositioning of the U-shaped support at the desired height to accommodate the patient. The support carriage connects the U-shaped support to the height-adjusting track and maintains the arrangement of the U-shaped support during the procedure. The X-ray generator and the image-capturing device enable the medical staff to perform the MBSS procedure on the patient.

An X-ray imaging apparatus includes an X-ray source, a detector for detecting X-rays, an imaging unit, an operation unit, a notification unit, and a control unit. The control unit generates an image of an inside of an examination room. Further, when detecting that a person other than a subject is present in the examination room based on the image of the inside of the examination room, the control unit performs control to issue caution information indicating that a person other than a subject is present in the examination room.

Interstitial brachytherapy is a cancer treatment in which radioactive material is placed closely to the target tissue of the affected site using an afterloader (HDR-brachytherapy) or manually (LDR- and PDR-brachytherapy). For HDR-brachytherapy, the accuracy of this placement is calibrated using an external reference system that locates the radioactive material according to the radiation levels measured at locations around the source. At each of these locations, a scintillator produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals.

Various methods and systems are provided for a radiation shielding component including a plurality of parts fused together by metal infiltrated through junctions between adjacent, interconnected parts. In one embodiment, members on a side of a panel may be interlocked with indentations on a side of another and then metal may be infiltrated through a junction between the two panels to fuse the adjacent panels.

Systems that can overcome the limitations of current blood flow measurement systems and systems that can track in 3D the explosively driven fragments traveling at 1,000 m/s or faster, will provide temporal resolution of 1 μs, spatial resolution of 50 μm to 1 mm (or finer based on geometry), and allow imaging over at least 122×122 cm.sup.2 area are disclosed hereinbelow. These systems use a double-pulsed X-ray generator.

Various methods and systems are provided for manufacturing a radiation shielding component of an imaging apparatus. In one embodiment, the radiation shielding component may be manufactured by infiltrating metal particles with a binder solution and then curing the binder solution impregnated with the metal particles. In another embodiment, the radiation shielding component may be printed with metal powder, infiltrated with a binding agent, and then cured to polymerize the binding agent.
