A method and devices for detecting deposits, in particular amyloid plaques, in the eye, in particular in the human eye. The subject is an optical method for detecting deposits, in particular &#x3b2;-amyloid, in the retina, which is locally resolved and wherein the local resolution is better than the layer thickness of individual layers of the retina. The invention includes a device for optically detecting &#x3b2;-amyloid in the retina, which generates a locally resolved image of the retina and wherein the local resolution is better than the layer thickness of individual layers of the retina.

Method and device for detecting deposits in the eye

A method for quantitative evaluation of an image and/or of an image sequence of tissue or tissue samples for the presence of pathological changes using a database in which there are stored pattern image data and/or pattern image data sequences of tissue patterns that have been identified as predominantly or definitely benign or malignant, and for each sample a weighting factor is stored which indicates whether the pattern occurs predominantly in benign or in malignant tissue changes; it is then analyzed whether any of the pattern images stored in the database are present, within predetermined tolerances, in the image and/or in the sequence of images; based on the sum of the weighting factors of the patterns present, an evaluation factor is formed and made available for further use or output.

In a high resolution ultrasonic tomograph operating according to transmission, scattering and impulse-echo methods, comprising a container with an open top and including ultrasonic transducers arranged along the walls of the container, a coupling medium disposed in the container and a computer-based control and evaluation unit with a working memory, the control and evaluation unit is connected in a circuit with the ultrasonic transducers in such a way that the ultrasonic signal emitted from at least one ultrasonic transducer forms an ultrasonic impulse which is received by all the other transducers in parallel and is amplified, filtered and digitized to form electric signals which are stored in the working memory as a data set.

In a magnetic resonance tomograph having a continuous channel for inserting from one end a stretcher with a female patient lying thereon in a prone position during magnetic resonance mammography, the tomograph is provided with a manipulator by which instruments for the diagnosis and surgical treatment of such patients breasts can be introduced into the channel from the other end and positioned in relation to the breasts which are disposed in the isocenter of the magnetic resonance tomograph. The manipulator has a support arm with a recess for receiving the various instruments which can be installed and exchanged from the other, that is, the proximal end. The support arm with the recess can be pivoted horizontally and vertically about a fixed point located outside the recess and beyond the tip at the distal end of the manipulator adjacent to a breast of the patient.
