发明名称 Strålknivskollimatorkonstruktion
摘要 A method of providing with precision a number of long and narrow through holes (11) in a body (1) made of a high-density material. The body (1) is made in the form of a number of partial bodies (2, 2', 2''), which are arranged close to each other and from the body (1). Each partial body (2, 2', 2'') is defined by an outer surface (5), which is part of the outer surface of the entire body (1), an inner surface (6), which is part of the inner surface of the entire body (1), as well as a pair of boundary surfaces (7, 8), which extend from the outer surface (5) to the inner surface (6). Holes (11) are produced by machining at least one of the bounding surfaces (7, 8) adjacent partial bodies (2', 2''). Each hole (11) extends from the outer surface (5) to the inner surface (6) along said at least one boundary surface (7, 8). The thus machined partial bodies (2, 2', 2'') are fixedly attached to each other.
