Abstract: A leaf module for a multi-leaf collimator comprises a leaf unit and a leaf drive unit. The leaf unit comprises a leaf for shielding beams from a selected area. The leaf unit is mounted displaceably in an adjusting direction with relation to the leaf drive unit. The leaf drive unit is designed to displace the leaf unit linearly in the adjusting direction. The leaf drive unit comprises at least one drive mechanism which operates based on piezoelectric actuation, being designed such that the leaf drive unit thoroughly encloses the leaf unit within a plane being oriented substantially perpendicularly related to the adjusting direction. The multi-leaf collimator can comprise a plurality of leaf modules while being shaped as compact as possible. Both precise and stable adjustability of the leaf unit is achieved with the leaf module.

Abstract: The invention relates to a method and device for operating collimator (1) for limiting a beam of high-energy radiation (2) which, starting from an essentially point-shaped radiation source (3), is directed onto an object (4) to be treated and which is used especially for stereotactic, conformal radiation therapy of tumors, wherein the collimator (1) has an iris diaphragm (5) as a beam-limiting means. For such a collimator (1), a high degree of shielding for minimal overall height and with a variable opening size of the diaphragm opening (12) is achieved, in that the iris diaphragm (5) has at least three diaphragm leaves (6, 6′, 6″, or 7, 7′, 7″, 7′″, or 8, 8′, 8″, 8′″, 8″″, or 9, 9′, 9″, 9′″, 9″″, 9′″″) which have touching side surfaces (10) enclosing the same angle (α), wherein the diaphragm leaves (6, 6′, 6″, or 7, 7′, 7″, 7′″, or 8, 8′, 8″, 8′″, 8″″, or 9, 9′, 9″, 9′″, 9″″, 9′″″) open up a beam-limiting opening (12) such that a sliding movement (13) along the side surfaces (10) takes place by a number of diaphragm leaves (6, 6′, 6″, or 7, 7′, 7″, 7′″, or 8, 8′, 8″, 8′″, 8″″, or 9, 9′, 9″, 9′″, 9″″, 9′″″) which is reduced by at most one.

Abstract: 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″).

Abstract: The invention relates to a patient positioning and transport system comprising a transportable stretcher (1) and a cart (2) for transporting the stretcher (1) with the patient. The stretcher (1) can be removed from the cart (2) to be placed on a diagnosis or treatment station (4). A patient positioning and transport system of the aforementioned type should be designed as to avoid, to the greatest possible extent, repositionings of the patient between separate diagnosis or treatment stations (4). Towards this end, at least one adapter plate (3) that can be assigned to the stretcher (1) is provided, whereby the stretcher (1), the adapter plate (3) and the cart (2) can be joined to another and are configured in such a manner that the stretcher (1) with the patient can be transferred from the cart (2) to various, differently designed diagnosis or treatment stations (4) and back.
