1. A radiography and radiotherapy apparatus, comprising:
a body unit;
a gantry configured to rotate relative to the body unit;
a treatment table on which an object is placed and configured to slide into holes formed in the body unit and the gantry and move in a vertical direction;
a gantry driving part configured to rotate the gantry;
a radiation irradiation part mounted on the gantry and configured to irradiate radiation toward the object;
an image detector mounted to face the radiation irradiation part on the gantry and configured to detect the radiation irradiated from the radiation irradiation part; and
a beam stopper provided at a lower end of the image detector and configured to block the radiation,
wherein the radiation irradiation part comprises:
a radiation source configured to generate the radiation;
a primary collimator configured to shield the radiation generated from the radiation source and determine a beam dispersion angle;
a variable filter part configured to adjust an intensity of the radiation from the primary collimator;
an ion chamber configured to monitor a dose of the radiation from the variable filter part; and
a multi-leaf collimator configured to adjust a distribution of the dose of the radiation from the ion chamber;
wherein the radiation irradiation part comprises a single radiation source, and the variable filter part adjusts an intensity of the radiation irradiated from the single radiation source to obtain a radiation dose suitable for both radiography and radiotherapy, and
wherein the treatment table comprises a rotary table provided at an end of the treatment table and detachable fastened thereto.
