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： The invention relates to a stop for arrangement on a drilling, milling or countersinking tool for machining a work piece, wherein the work piece has a surface, and wherein the drilling, milling or countersinking tool has a cutting section. The stop comprises a contact surface, wherein the contact surface is arranged such that once a predetermined machining depth in the work piece is reached, the contact surface is seated against the surface, at least in some sections. A connecting element is provided, wherein the connecting element is arranged between the contact surface and the cutting section. The connecting element is suited to prevent a relative movement between the contact surface and the surface.
