The invention is concerned with the treatment head (200, 700) for a photon therapy unit (100), said treatment head (200, 700) having a plurality of discrete arrays of photon emitters (210), each having a support (1001) for said photon emitters (210) to maintain said photon emitters (210) in spaced relationship on a respective array (210), said arrays (210) being arranged in seriatim and flexibly connected to one another to facilitate said head (200, 700) conforming to a treatment location. Also, the invention is concerned with a photon therapy unit (100) having a treatment head (200, 700) including at least one photon emitter (210, 702), a drive circuit (1006) to drive said at least one photon emitter (210, 702), a control (104) to modulate said drive circuit (1006) and a switch (716) responsive to placement of said head (200,700) on a treatment location, said switch (716) inhibiting operation of said drive circuit (1006) until said emitter (210) is placed on the treatment location and including at least one pair of terminals (718, 720) at spaced locations on said head (200, 700) and positioned relative to said photon emitter (210, 702) to contact skin at the treatment location to complete an electrical circuit upon placement of said head (200, 700) on the treatment location with said emitter (210, 702) directed to the treatment location. |
