US 2013/0294571 A1 · X-RAY TUBE AND X-RAY CT DEVICE

Abstract

Disclosed is an X-ray tube that has a simple configuration and is capable of irradiating multiple different X-rays while switching them at a high rate, as well as an X-ray CT device using the X-ray tube. The X-ray tube comprises first and second electron generators, a deflection means, and a target. The deflection means switches the direction in which first and second electron beams are transmitted between first and second directions. The target comprises first, second, third, and fourth surfaces. The first surface receives a first electron beam transmitted toward the first direction and irradiates a first X-ray toward the irradiation field. The second surface receives a second electron beam transmitted toward the first direction and irradiates a second X-ray toward a direction different from the irradiation field. The third surface receives a first electron beam transmitted toward the second direction and irradiates the first X-ray toward a direction different from the predetermined irradiation field. The fourth surface receives a second electron beam transmitted in the second direction and irradiates the second X-ray toward the irradiation field.

Dependent claims

An X-ray tube comprising:

a first electron generator that emits a first electron beam;
a second electron generator that emits a second electron beam with a different energy from the first electron beam;
a deflection means configured to be able to simultaneously switch the directions in which the first electron beam and second electron beam are transmitted to either a first direction or a second direction that is different from the first direction;
and
an X-ray generator that comprises:
a first surface that receives a first electron beam transmitted in the first direction and irradiates a first X-ray toward a predetermined irradiation field,
a second surface that receives a second electron beam transmitted in the first direction and irradiates a second X-ray that is different from the first X-ray toward a direction different from the predetermined irradiation field,
a third surface that receives a first electron beam transmitted in the second direction and irradiates the first X-ray toward a direction different from the predetermined irradiation field, and
a fourth surface that receives a second electron beam transmitted in the second direction and irradiates the second X-ray toward the predetermined irradiation field.
