    摘要: The invention relates to a collimator (1) for limiting a bundle of high-energy rays (2), which is emitted by a substantially point-like radiation source (3) and directed towards a treatment object (20) and used in particular for the stereotactic conformation radiotherapy of tumors. According to the invention the collimator (1) comprises a plurality of diaphragm leaves (4, 4′) which are arranged opposite each other and which are made of a radiation-absorbing material and which, by means of drive mechanisms, can be moved into the optical path in such a way that the contours and/or exposure period of said optical path can be freely defined, the front edges (5, 5′) of the diaphragm leaves (4, 4′) being parallel to the optical path at all times. Avoiding penumbral shadows with this kind of collimator (1) is made considerably easier if the diaphragm leaves (4, 4′) consists of a rear partial element (6, 6′) which can be linearly displaced and a front partial element (7, 7′) which is hinged to same. Drive means adjust the front partial element (7, 7′) in accordance with the prevailing position of the rear partial element (6, 6′) in such a way that the front edges (5, 5′) are parallel to the optical path at all times.

    摘要: The invention relates to a displacement-detecting element (1) comprising a measuring resistance (2), voltage source (3) and a displacement-dependent voltage pick off (4). The measuring resistance (2) is embodied in the form of a strip. The length of the resistor (6) corresponds to at least the maximal length of displacement (7) of the component to be detected. The invention also relates to a multileaf collimator (23) having such a displacement-detecting element (1). The aim of the invention is to produce a displacement-detecting element (a) for detecting the position of the leaves (22) in a multileaf collimator (23) in a precise and faultless manner. The displacement detecting element (1) is designed for detecting the displacement (7′) of the leaves (22) in a multileaf collimator (23) in the following manner: the measuring resistance (2) or the voltage pick off point (4) are connected in a rigid manner to the leaves (22) in order to detect the displacement and another functioning element (4 or 2) is arranged in a fixed manner. At least one of these functioning elements (2, 4) is disposed in an area (33, 33′, 33″) of the leaves (22), which is not exposed to main radiation (34).

    摘要: A contour collimator for radiation therapy has a plurality of diaphragm elements that are movable with respect to each other by means of drive units. The diaphragm elements of the invention are supported only on the side near the drive units for ease of movement. This allows larger contour collimators to be constructed having relatively heavy diaphragm elements while retaining relatively small motors.

    摘要: The invention relates to a collimator (1) for defining a beam of energetic rays (2) which is emitted from an essentially punctiform radiation source (3) and is oriented onto an object (1) to be treated. The collimator is especially used for the stereotactic conformation radiotherapy of tumors. The collimator (1) is embodied in such a way that an irregular object (4) can be scanned by rays (2, 2′) which are defined by an opening in the collimator. The invention also relates to a program for controlling the collimator. In order to define the contours (29, 29′, 29″) of the objects (4) to be irradiated in a simple but highly accurate manner, especially with a precise definition of the irradiation fields, the collimator comprises a plurality of different sized openings (5, 5′ 5″). One of the openings (5, 5′, 5″) can be selectively displaced in a polydirectional manner on a strip (6) having a spherical surface, and the central axis (7) thereof is oriented towards the radiation source (3). The other collimator openings (5′, 5″) are shielded form the rays (2). A control system (9) acts on the drives (23, 24, 25) of a drive device (8) in such a way that large openings (5, 5′) are used to scan large irradiation surfaces (26) of the object to be treated (4), and small openings (5′, 5″) are used for precise definition at the edge of the irradiation surfaces (26) of the object to be treated (4), especially in the event of irregular contours (29, 29′, 29″).

    摘要: A body part such as a patient's head is positioned for treatment purposes by holding a treatment point defined relative to marks attached to the body part is held in a desired position. To this end, at least two picture signal generating sensors are aligned to observe the marks. A picture processing device for processing the pictures of the marks is provided to define marker points, which are determined by the marks and define the actual position of the body part. Furthermore, a signal processing and control device is provided for computing the actual position from the observed positions of the marker points, for comparing the actual position with a desired position and for generating actuating signals, which depend on the error between actual position and desired position. The actuating signals are applied to actuators, which engage the body part. Thereby the treatment point can be returned to the desired position, if it has deviated therefrom.
