摘要： A radiotherapeutic apparatus comprises a source of therapeutic radiation, a source of visible light arranged to cast a light field corresponding to the beam of radiation, and a multileaf collimator for shaping the beams, wherein a filter is disposed in the path of the visible light beam having a plurality of linear dark sections corresponding to leaves of the collimator. This prevents the incident light from falling on the leaves and removes the ghost images at source. By placing the filter in the head, the line can be very narrow and will be blurred into penumbra at the isocentre. This is therefore a very inexpensive yet effective method of reducing ghosting. A mirror can deflect the path of the visible light to correspond to that of the radiation beam, and the filter can be disposed anywhere in the beam path, such as prior to the mirror, subsequent to the mirror and prior to the collimator, or subsequent to the collimator. The filter thus creates dark sections in the light field corresponding to leaves (preferably all the leaves) of the collimator.

摘要： A multi-leaf collimator for use in a radiotherapeutic apparatus comprises a plurality of elongate narrow leaves arranged side-by side and supported in a frame, the frame having upper and lower formations for guiding each leaf into which extend ridges on the upper and lower edges of the leaves, thereby to allow the leaves to move in a longitudinal direction, the upper and lower formations being aligned so that the sides of the leaves when fitted are at a non-zero angle to the beam direction, the upper and lower ridges being located on the upper and lower edges of the leaves so that a line joining their centres is at a non-zero angle to the sides of the leaf, tilted relative to the sides in a sense opposite to that of the beam. An outer face of the upper and/or lower ridges can be aligned with a side face of the leaf, for ease of manufacture. A radiotherapeutic apparatus is also disclosed, comprising a source of radiation and a multi-leaf collimator for shaping the radiation emitted by the source, the multi-leaf collimator being as set out above.

摘要： A patient support system comprises a base, an upstanding support, and a couch attached to the support and having a cantilever section extendable beyond the support; the support including a couch drive means to adjust the position of the couch relative to the support; further comprising a support drive means for translationally driving the support relative to the base in the direction of the cantilever section. This removes inaccuracies from patient position measurements that result from changes in the cantilever geometry during movement of the patient from a measuring position to a treatment position. The support drive means can be located in the base or in the support, and allows the patient support system as a whole to be translated, thereby permitting the patient to be moved into and out of an enclosed treatment area without affecting the vertical location of the patient. The only change to the patient position is in the translational position, which can be calibrated by way of fixed end stops for the support drive means. The present invention further relates to a radiotherapy apparatus, comprising a patient support as set out above, and an enclosed treatment area positioned in line with the cantilever section.
