In one embodiment, a method for imaging a tumor of a patient comprises the steps of: (1) simultaneously detecting spatially resolved positively charged particle positions passing through each of a set of cross-section planes, where the cross-section planes are both prior to and posterior to the patient along a path of the positively charged particles; (2) determining a prior vector for each of the individual positively charged particles entering a patient using the detected positions; (3) determining a posterior vector for each of the individual positively charged particles exiting the patient using the detected positions; (4) generating a probable path of each positively charged particle through the patient; and (5) generating an image of the patient using the n probable proton paths and optionally a detected residual energy of each proton.

A radiation therapy apparatus capable of improving the accuracy of a dose distribution includes an X-ray generation device that is provided at an arm portion of a rotation gantry, a radiation detector that is insertable into the body of a patient, a dose calculation device, and a feedback control device. An X-ray generated due to collision of an electron beam with a target in the X-ray generation device is applied to an affected part (cancer) of a patient on a bed. The radiation detector which is insertable into the body detects the X-ray applied to the affected part so as to output a photon to obtain a dose rate and a dose based thereon. The feedback control device either controls the X-ray generation device such that the obtained dose becomes a set dose or controls the radiation generation device such that the obtained dose rate becomes a set dose rate.

A radiation imaging apparatus is provided. The apparatus includes a radiation detection panel, a housing of a cuboid shape that accommodates the radiation detection panel. The housing has a front surface that the radiation enters, a rectangular back surface arranged on a side opposite to a side of the front surface, and four side surfaces configured to connect the front surface and the back surface. The apparatus further includes a grip portion which is concave toward the radiation detection panel, formed in a peripheral region on the back surface. The grip portion has at least one of a depth not less than one-half a distance between the front surface and the back surface, and a depth not less than a distance between the back surface and a center of gravity of the radiation imaging apparatus.
