摘要： An x-ray beam from a source 10 has dimensions determined by a collimator 26 comprising plates (28a, 28b, 30a and 30b) adjusted by electric motors (32 and 34) respectively. An indicator (60) for indicating the dimensions of the x-ray beam is located on the other side of the patient from the collimator (26) and comprises two pairs of light sources, one pair of which (62 and 64) are movably mounted on a bar (66). These light sources are mounted for both linear and angular movement and are controlled to move with the collimator plates so that as the plates are moved toward and away from each other, the light sources are correspondingly moved and rotated. The light planes (76 and 78) from the respective light sources (62 and 64) and corresponding planes from the other two sources lie on the extension of the x-ray beam (12) formed by collimator (26) and converge at the source (10) of the x-rays so as to provide an outline on the patient of the x-ray beam which is visible to the operator. The control system for the light sources includes sources (42, 46) providing signals indicative of the desired and actual positions of the collimator plates (28), and sources (50, 52) providing signals indicative of the desired and actual positions of the x-ray source (10). These signals control the rotation of a motor (96) driving a drum (94) controlling the movement of a cable (90) having portions connected to control the light sources (62, 64).

摘要： A camera (35) generates digital image signals representing an image of one or more natural or artificial fiducials (39) on a patient positioned on treatment or diagnosis equipment. A processor applies multiple levels of filtering at multiple levels of resolution to repetitively determine successive fiducial positions. A warning signal is generated if movement exceeds certain limits but is still acceptable for treatment. Unacceptable displacement results in termination of the treatment beam (15). Tracking templates can be generated interactively from a display of the digital image signals or through automatic selection of an image having the median correlation to an initial template. A gating signal synchronized to patient breathing can be extracted from the digital image signals for controlling the radiation beam generator.

摘要： The disclosure relates to a method for localising the three-dimensional position of a spot in an object in conjunction with X-ray exposure of the object, in which the object is fixed in a pre-determined position and is exposed by means of an exposure apparatus in two directions each on either side of a centre line at a right angle to the plane of the image or obtaining a first print and a second print, the two-dimensional position of the target spot on the two prints being established in relation to an index on the prints, and the coordinates of the spot in relation to the indices being processed to obtain control signals for adjustment of a guidance instrument with means for placing in the target spot in the object.

摘要： External alignment lights mounted on the gantry of a tomography system to project on a staged patient a pattern showing the anatomy to be scanned by the system when the patient is translated from the staged position to the scanning position within the cylindrical opening of the gantry. Parallax correction means senses the angulation of the gantry with respect to the axis of translation of the patient table and modifies the translation distance of the table used to bring the patient into the scanning position.

摘要： The invention relates to a filter arrangement in a radiography apparatus in order to define the intensity of the radiation beam incident upon the object. To the movable filter part in front of the radiation source (2) there is coupled an electric circuit element, for example a potentiometer, from which the signal is applied further to a row (8) of light-emitting diodes in the vicinity of the object to be radiographed, for example the patient's head (7). When the filter is moved, the electric signal controls the light-emitting diodes so that the light-emitting diodes which become illuminated in the row will indicate the boundary of the filtered radiation beam at a given time.

摘要： An alignment method and system for aligning an anti-scatter grid with an x-ray source of a radiographic apparatus, to facilitate accurate alignment of the central x-ray beam of the x-ray source of the radiographic apparatus with a focused grid. The present invention uses a first light projector that is substantially fixed relative to the x-ray source, which produces a first alignment image that is substantially fixed relative to the grid. Also included is a second light projector that is substantially fixed relative to the grid, and that produces a second alignment image that is substantially fixed relative to the x-ray source. The first light projector is preferably the collimator light included within the collimator housing of the x-ray apparatus, and the second light projector is preferably a laser light source, that is attachable to a grid cassette holding the grid.

摘要： A method for the treatment of atherosclerosis in a mammal by destruction of atheromatous plague. The disclosed method includes injecting a hematoporphyrin into the mammal for selective uptake into the atheromatous plague (16), and delivering light to the diseased vessel (10) so that the light activates the hematorporphyrin for lyses of the plague (16). The preferred method utilizes a balloon catheter (14, 12) equipped with flexible optical fibers (20) for transmission of light from an external source for illumination of the interior of the inflated balloon (14). By inflation of the balloon (14), the opaque blood between the balloon (14) and the atheromatous plague (16) is displaced to facilitate activation of the hematoporphyrin. The balloon (14) may be illuminated and inflated and deflated in a cycle responsive to the patient's pulse so as to minimize interference with blood flow.

摘要： The invention concerns a position-determination system using at least one marker, and a marker for use in such a system. The markers (1) are novel in that their active transmission power - normally pulses of light or similar energy - is fed in by means of optical waveguides (3) so that no detectable electrical currents occur in the region of the marker (1). Patients therefore have optimum protection against undesirable electrical interference.

摘要： Subsurface region (59) of an X-ray transparent but optically opaque object (60) are targeted along a visible line of sight (42) obtained by the use of two radiation sources (an X-ray (46) and light beam source, preferably a laser). The central ray from the X-ray source and the light beam are aligned using a calibration fixture (15), one to the other and both with respect to structures internal to the object being imaged to provide the visible line of sight. The system, method and apparatus may be used in surgical applications for selective illumination and sighting to reach specific subsurface members of a patient's anatomy by guiding an incision.
