Abstract
A structure according to an embodiment is disposed between an X-ray emitter and a subject, and includes a scatterer configured to scatter X-rays emitted from the X-ray emitter, and a transmitter configured to transmit X-rays at a predetermined angle, among the X-rays scattered by the scatterer.
Claims19
A structure that is disposed between an X-ray emitter and a subject, the structure comprising:
- a scatterer made of a material capable of scattering X-rays and transmitting the scattered X-rays, the scatterer being configured to scatter X-rays emitted from the X-ray emitter, wherein the scattering of the X-rays by the material is either Compton scattering or Thomson scattering;
- and
- a transmitter configured to transmit X-rays at a single, predetermined angle, among the X-rays scattered by the scatterer,
- wherein the scatterer has a convex-shaped portion on an incidence surface, where the X-rays emitted from the X-ray emitter become incident.

An X-ray diagnostic apparatus, comprising:
- an X-ray emitter configured to emit X-rays;
- a structure provided between the X-ray emitter and a subject;
- and
- an X-ray detector configured to detect X-rays transmitted through the structure, wherein
- the structure includes:
- a scatterer made of a material capable of scattering X-rays and transmitting the scattered X-rays, the scatterer being configured to scatter the X-rays emitted from the X-ray emitter, wherein the scattering of the X-rays by the material is either Compton scattering or Thomson scattering;
- and
- a transmitter configured to transmit X-rays at a single, predetermined angle, among the X-rays scattered by the scatterer,
- wherein the scatterer has a convex-shaped portion on an incidence surface, where the X-rays emitted from the X-ray emitter become incident.
6 more elements
A method, comprising:
- emitting X-rays from an X-ray emitter;
- and
- detecting, with an X-ray detector, X-rays at a single predetermined angle from the emitted X-rays that are (1) scattered by a scatterer made of a material capable of scattering X-rays and transmitting the scattered X-rays, and (2) transmitted through a transmitter, wherein the scattering of the X-rays by the material is either Compton scattering or Thomson scattering,
- wherein the scatterer has a convex-shaped portion on an incidence surface, where the X-rays emitted from the X-ray emitter becomes incident.
