DETECTION OF SMALL BREAST TUMOURS BY RADIONUCLIDE IMAGING

摘要

The invention concerns a Device for detecting small tumours or lesions in the diagnosis of breast cancer by means of molecular imaging using radionuclides, comprising a first and second detector, between which the mamma is to be positioned, characterised in that: said second detector (20) has the same dimensions of the mammographical film and said first detector (10) has dimensions that are smaller than those of the mammographic film and such to be suitable to realise a spot compression and therefore reduce the distance lesion-detector; said second detector (20) is fixedly mounted on a support (30) that extends in a direction z; said first detector (10) is mounted: on a mobile support (30) along said direction z (30), for the compression of the mama; in a rotatable way on said mobile support so as to be suitable to form an angle α between 0 and 90 with the direction z, for minimizing the distance lesion-detector in the cases of tumours close to thorax, and in a movable way in the xy plane on said mobile support for the optimal positioning with respect to the mamma.
