ELECTRONICALLY CONTROLLED CAPSULE FOR RELEASING RADIATION

摘要

A method and system (2100) are provided for dispensing radiation to a patient from a location internal to the patient. The system (2100) includes a radioactive assembly (2106) having a radioactive material (2107); a first radiation resistant assembly (2102) having at least one first radiation resistant panel (2116), wherein at least one gap (2122) is formed in the first radiation resistant assembly (2102) for allowing radiation to pass there through to the ambient environment of the capsule; an actuator; and a second radiation resistant assembly (2104) having at least one movable second radiation resistant panel (2136) operationally coupled to the actuator for controllably moving the second radiation resistant assembly (2104) for positioning a respective second panel to a position with respect to a respective gap for selectively covering at least a portion of the respective gap for impeding passage of radiation through the respective gap to the ambient environment of the capsule; and control circuitry (906) for controlling activation of the actuator.
