Medical imaging equipment

Abstract

The invention relates to medical imaging equipment (1) comprising a radiation source (3) for emitting measuring radiation (4), a receiver for receiving the measuring radiation (4) that is emitted by the radiation source (3), in addition to a measuring region, in which an object (7) to be measured is placed and which is situated in the beam path of the measuring radiation (4), between the radiation source (3) and the receiver. According to the invention, the receiver comprises a support (5), which can be pivoted about a rotational axis (10), has at least two receiving surfaces (11, 12) for the measuring radiation (4) and displaces the receiving surfaces (11, 12) alternately into a measuring position. Said receiving surfaces (11, 12) run essentially parallel to the rotational axis (10) of the carrier (5) and the rotational axis (10) of the carrier (5) is essentially perpendicular to the beam path of the measuring radiation (4).

Description

technical field [0001] The invention relates to a medical imaging device, in particular a device for acquiring mammographic images, having the features stated in the preamble of independent claim 1 . Background technique [0002] Mammography is a type of x-ray examination of the breast that uses medical imaging equipment to obtain mammograms. Such devices usually have a radiation source for emitting x-rays. X-rays are used to perform fluoroscopy on the breast to be examined, and obtain a fluoroscopic image on an X-ray film arranged on an optical path below the breast. During the examination, the breast is typically held between a compression retention plate and a target support. [0003] The advantages of using X-ray film are: firstly, the use of X-ray film is quite mature in technology, and it is also a low-cost solution in terms of purchase; save. [0004] Another advantage of using X-ray film is that the receiving area of ​​X-ray film is very large, usually 18×24cm or...

Problems solved by technology

[0024] The disadvantage of this device is that, due to the large range of motions of the receiving surfaces 71 , 72 fixed on the bracket 65 when they are rotated, the device takes up a lot of space 73 for this purpose.

[0025] In addition, the corresponding rotatable mechanical couplings connected to the respective receiving surfaces 71, 72 are not only technically demanding but also expensive to manufacture, since their precision must meet the requirements of the medical field.
