Title:
X-RAY TUBE AND X-RAY CT DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/002124
Kind Code:
A1
Abstract:
Provided are an X-ray tube with which irradiation is possible while rapidly switching a plurality of different x-rays with a simple configuration, and an x-ray CT device employing same. An x-ray tube comprises first and second electron emission units, a deflection means, and a target. The deflection means switches the directions in which first and second electron beams are transmitted to first and second directions. The target further comprises first, second, third, and fourth faces. The first face receives the first electron beam in the first direction and projects a first x-ray toward an irradiation field. The second face receives the second electron beam in the first direction and projects a second x-ray in a direction different from the irradiation field. The third face receives the first electron beam in the second direction and projects the first x-ray in a direction different from a prescribed irradiation field. The fourth face receives the second electron beam in the second direction and projects the second x-ray toward the irradiation field.
