Abstract
The present disclosure relates to an X-ray source apparatus and a control method of the X-ray source apparatus in which a cathode electrode and a gate electrode are arranged in an array form to enable matrix control, and, thus, it is possible to irradiate X-rays at an optimum dose for each position on the subject. Therefore, it is possible to suppress the irradiation of more X-rays than are needed to the subject. Also, it is possible to obtain a high-resolution and high-quality X-ray image. As such, two-dimensional matrix control makes it easy to control the dose of X-rays and makes it possible to uniformly irradiate X-rays to the subject. Therefore, it is possible to manufacture a high-resolution surface X-ray source with less dependence on the size of the focus of electron beams.
