摘要： Embodiments of the present invention provide a system and a method for attaching peripheral devices (such as collimators and electron applicators) to a system such as a radiotherapy system or radiography system. By re-using the lifting mechanism of the patient support to lift the peripheral device vertically, the invention reduces the need for heavy manual lifting.

摘要： Radiotherapy apparatus comprises a source of radiation mounted on a chassis, the chassis being rotatable about a rotation axis and the source being adapted to emit a beam of radiation along a beam axis that intersects with the rotation axis; a patient support, moveable along a translation axis; a set of magnetic coils located on either side of the beam, for establishing a magnetic field at the point of intersection, spaced from that point along a first direction; the translation axis, the rotation axis, and the first direction being substantially parallel; and further comprising a multi-leaf collimator fixed in its orientation with respect to the source of radiation, the multi-leaf collimator comprising a plurality of elongate leaves disposed with their longitudinal directions substantially aligned with the first direction and movable in that direction between a withdrawn position in which the leaf lies outside the beam, an extended position in which the leaf projects across the beam and a plurality of intermediate positions therebetween.

摘要： There is provided a sensor array, comprising a pair of transducers, a first transducer, configured to transmit pressure waves; and a second transducer, acoustically coupled to the first transducer, configured to detect pressure waves incident upon the sensor array from the environment. The array further comprises control circuitry, coupled to the first and second transducers, configured to: control the first transducer to transmit pressure waves; simultaneously control the second transducer to monitor the transmission of said pressure waves; and verify correct operation of the array in the event that said pressure waves are detected. The invention therefore provides a sensor array with a failsafe mechanism.
