Kind Code:

A1

Abstract:

A radiography and radiotherapy apparatus according to one embodiment of the present invention comprises: a body unit; a gantry that can rotate around the body unit; a treatment table on which an object is placed and can slide toward holes formed in the body unit and the gantry, and which can move in the vertical direction; a gantry driving unit for rotating the gantry; a radiation emission unit which is mounted at the gantry and which emits radiation at the object; an image detector which is mounted at an opposing location on the gantry of the radiation emission unit, and which detects the radiation emitted from the radiation emission unit; and a beam stopper which is located at the lower end of the image detector, and which blocks the radiation. The radiation emission unit comprises: a radiation source for generating the radiation; a first collimator for blocking the radiation generated by the radiation source and determining a beam dispersion angle; a variable filter unit for adjusting the intensity of the radiation from the first collimator; an ion chamber for monitoring the dose of radiation from the filter unit; and a multi-leaf collimator for adjusting the dose distribution of radiation from the ion chamber.
