A method of irradiating a target in a patient comprising directing a beam of radiation from an external source of radiation 24 at the target in the patient from numerous directions in a broad solid angle by longitudinally rotating the external source of radiation 24 around a central axis and simultaneously or sequentially, in either order, latitudinally rotating the external source of radiation 24; a globe gantry 21 comprising (i) a front opening ring 22 with its origin on the central axis of the globe gantry 21, (ii) at least one arc-shaped, gantry support arm 23, which has a front end and a rear end and is part of a circle, (iii) an external source of radiation 24, which is mounted on at least one arc-shaped, gantry support arm 23, (iv) a rear rotational axle 25 with an axis along the central axis of the globe gantry 21, (v) a support base 27, and (vi) a rear housing 26 comprising a source of power, mechanisms for moving components of the globe gantry 21, and controllers for controlling the movement of the components of the globe gantry 21 and the irradiation of the target in the patient; a system 20 comprising the globe gantry 21; and a method of irradiating a target in a patient using the system. |

1. A globe gantry for longitudinally and latitudinally rotating at least one external source of radiation concentrically around an isocenter placed in a target to be irradiated in a patient, which globe gantry has a central axis intersecting the isocenter and which comprises:
(i) a front opening ring with its origin on the central axis of the globe gantry, (ii) at least one arc-shaped, gantry support arm, which has a front end and a rear end and is part of a circle with its origin at the isocenter, (iii) an external source of radiation, which is mounted on at least one arc-shaped, gantry support arm of (ii), wherein the external source of radiation moves along the at least one arc-shaped, gantry support arm, thereby rotating latitudinally, and directing a beam of radiation at the isocenter, and optionally, a beam stopper, which is mounted on at least one arc-shaped, gantry support arm of (ii), and wherein the beam stopper is on an opposite side of the globe gantry from the external source of radiation, (iv) a rear rotational axle with an axis along the central axis of the globe gantry, (v) a support base, and (vi) a rear housing comprising a source of power, mechanisms for moving the globe gantry, and controllers for controlling movement of the globe gantry and the irradiation of the target in the patient, wherein the front opening ring is attached to the front end of the at least one arc-shaped, gantry support arm, wherein the rear rotational axle is attached to the rear end of the at least one arc-shaped, gantry support arm, wherein the front opening ring and the rear rotational axle are supported by the support base and the rear housing, and wherein the front opening ring and the rear rotational axle can rotate around the central axis. |
