Patent number: 7132674Abstract: 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).Type: GrantFiled: October 23, 2002Date of Patent: November 7, 2006Assignee: Deutsches Krebsforschungszentrum Stiftung des Offentlichen RechtsInventors: Otto Pastyr, Gernot Echner, Wolfgang Schlegel, Günther Hartmann

Patent number: 5343048Abstract: A contour collimator for shaping a radiation beam for radiation therapy has two sets of radiation-impermeable lamellae disposed opposite each other, with each lamella being individually displaceable toward and away from its counterpart lamella in the other set. The sets of lamella are disposed between lateral walls of holder, at least one of which can be loosened and tightened. The lamellae are normally urged against each other by a spring force acting on each lamella. A user-manipulable mechanism is operable for displacing all of the lamellae in both sets away from each other, so that a form conforming to the desired contour can be placed between the lamellae. The mechanism is then moved to permit the spring force to act on each lamella, causing the lamellae to abut the form. The lamellae are then clamped in position.Type: GrantFiled: February 1, 1993Date of Patent: August 30, 1994Assignee: Siemens AktiengesellschaftInventor: Otto Pastyr

Patent number: 5315630Abstract: 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.Type: GrantFiled: March 10, 1993Date of Patent: May 24, 1994Assignee: Bodenseewerk Geratetechnik GmbHInventors: Volker Sturm, Otto Pastyr, Wolgang Schlegel, Christoph Uihlein, Thomas Mack
