Abstract
An apparatus for communicating with a radiation therapy device comprises a first plurality of omnidirectional radio antennas 212, 214 mounted upon a rotor 202, and a second plurality of omnidirectional radio antennas 216, 218 positioned at respective fixed locations off the rotor. The first plurality of antennas 212, 214 may be substantially equally spaced around the axis of rotation of the rotor 202. The first plurality of antennas 212, 214 and the second plurality of antennas 216, 218 are positioned so as to allow line-of-sight radio communication between at least one of the first plurality of antennas and at least one of the second plurality of antennas at all angles of rotation of the rotor 202.
Claims18
A radiation therapy apparatus comprising:
- a rotor that is rotatable about an axis of rotation to a plurality of angles of rotation;
- a first plurality of omnidirectional radio antennas positioned on the rotor;
- and
- a second plurality of omnidirectional radio antennas configured to communicate with the first plurality of antennas, wherein each of the second plurality of antennas is positioned at a respective fixed location off the rotor so as to allow line-of-sight radio communication between at least one of the first plurality of antennas and at least one of the second plurality of antennas at each angle of rotation,
- wherein the second plurality of antennas comprises a first antenna positioned above the axis of rotation and a second antenna positioned below the axis of rotation.
