摘要： In various embodiments, a system for controlling radiotherapy equipment in a treatment environment includes a controller for receiving, from one or more image capture devices, data indicating the position of one or more objects in the treatment environment. Based on the position data, the controller defines one or more exclusionary zones from which the radiotherapy equipment is excluded. Each zone has a buffer area surrounding one or more of the objects. The controller further directs the radiotherapy equipment such that a radiotherapy treatment plan is delivered without the equipment entering into the exclusionary zones.

摘要： For Respiration Correlated Cone Beam CT scanning, we have observed that improvements in the frame rate are in fact undesirable. We therefore propose a radiographic apparatus comprising a beam of radiation and a detector therefor, adapted to obtain a two dimensional image of the beam after passing through a cyclically varying object to be investigated, a processor adapted to review the images and select images at like points in the cycle, and a control means for the beam of radiation adapted to activate the beam periodically. The control means can activate the beam at a frequency of between 0.5 and 5 Hertz, more preferably between 1 and 3 Hertz, which corresponds (roughly) to a frequency that is between 6 and 10 times the frequency of the cyclical variation. It will assist if the selected point of the cycle is an extremity thereof, as the rate of change in these areas is at a minimum. Thus, slight mismatches between the two cycles will then have only a small effect. Typically, the object will be a patient and the cyclical variation will be the patient's breathing cycle.

摘要： Flat panel images obtained during concurrent radiotherapy typically suffer from artefacts that relate to the pulses of MV energy. For a radiotherapeutic apparatus comprising a pulsed source of therapeutic radiation, a detector comprising control circuitry, an array of pixel elements, each having a signal output and an ‘enable’ input and being arranged to release a signal via the signal output upon being triggered by the enable input, and an interpreter arranged to receive the signal outputs of the pixel elements, the interpreter having a reset control, there are advantages in the control circuitry being adapted to reset the interpreter after a pulse of therapeutic radiation, prior to enabling at least one pixel of the array. Alternatively, the control circuitry can prompt a plurality of pulses by the pulsed source and then enable a plurality of pixels of the array. In effect, the therapeutic pulses are grouped into a short flurry of pulses. It is therefore preferred that the plurality of pixels comprises substantially all the pixels of the array.

摘要： A reference phantom includes CT-imageable detail together with light-reflective spheres. This item can be placed on a patient table in a known location, following which the diagnostic source can be activated to detect the phantom position relative to the isocentre and camera employed to detect the PSS position. A synthetic image of the phantom can be used for comparison with the CT dataset. This allows improved correlation of the source and the patient support, enable further steps to be taken in enhancing the clinical effectiveness of the apparatus. In-use variations of the isocentre location can be corrected in real time by adjustment of the patient support. Thus, as the isocentre moves, the patient can be moved so as to track the moving isocentre. The linac arm could also be designed differently, as the existing design constraint (that isocentre movement must be limited as far as possible) could potentially be relaxed in order to achieve other aims.

摘要： A method of detecting the presence of an insult in an absorbent article. An electrical property of the article is measured and either a proportional difference or a rate of change of the electrical property is determined. The proportional difference or the rate of change is compared to a difference indicator value and a rate indicator value, respectively, to determine the presence of an insult in the article.

摘要： Absorbent articles incorporating a wetness sensor for indicating the presence of a body fluid are disclosed. In particular, the absorbent articles include at least two conductive elements that form an open circuit within the article. Each conductive element is connected to a conductive pad member that has sufficient surface area in order to facilitate connection to a signaling device. In accordance with the present disclosure, various attachment mechanisms are disclosed for attaching the pad members to a signaling device. In particular, although the absorbent articles are disposable, the signaling device is intended to be used with multiple absorbent articles. Therefore, a simple and efficient method of connecting the signaling device to the pad members provides various advantages. In one particular embodiment, for instance, the pad members comprise a conductive loop-type material that is attached to a corresponding conductive hook-type material on the signaling device.
