## Abstract

In a method for representation of medical image information on a display medium an image representation parameter is varied dependent on the position of the observer. Superimpositions of data sets from different medical examinations are thereby displayed. The observer thus has simultaneous access to information from the medical examinations, which makes the diagnosis easier for him or her.

## Claims

### Claim 1

A method for displaying medical image information comprising the steps of:
detecting a position of an observer relative to a display screen; and
in a processor provided with medical data sets respectively representing different medical diagnostic images of the same region of a subject, generating and displaying a superimposition of medical data sets, comprised of relative, respective contributions of each data set to the superimposition, to produce a displayed, superimposed image of said region on said display screen, and said processor setting said relative, respective contributions of each data set to said superimposition simultaneously with and solely dependent on the detection of the position of the observer relative to said display screen, and changing an appearance of said displayed superimposed image of said region to the observer by changing said relative, respective contributions simultaneously with and solely dependent on a change in the detection position of the observer.

### Claim 2 (depends on 1)

A method as claimed in claim 1 comprising generating said superimpositions by simultaneously displaying at least two of said data sets weighted with respective weighting factors.

### Claim 3 (depends on 1)

A method as claimed in claim 1 comprising altering at least one image representation parameter associated with displaying said medical image information, dependent on said detected position of the observer.

### Claim 4 (depends on 3)

A method as claimed in claim 3 comprising altering brightness as said image representation parameter.

### Claim 5 (depends on 3)

A method as claimed in claim 3 comprising altering contrast as said image representation parameter.

### Claim 6 (depends on 1)

A method as claimed in claim 1 comprising generating at least one of said data sets from a plurality of partial data sets by maximum projection.

### Claim 7 (depends on 1)

A method as claimed in claim 1 comprising generating at least one of said data sets from a plurality of partial data sets by a partially transparent representation of surfaces.

### Claim 8 (depends on 1)

A method as claimed in claim 1 comprising generating at least one of said data sets from a plurality of partial data sets by a parameterized volume rendering technique.

### Claim 9 (depends on 1)

A method as claimed in claim 1 comprising detecting edges of said data sets with an edge detection algorithm.

### Claim 10 (depends on 9)

A method as claimed in claim 9 comprising adapting the respective data sets to each other at said display screen dependent on the detected edges.

### Claim 11 (depends on 1)

A method as claimed in claim 1 comprising displaying said different medical diagnostic images as two-dimensional medical images at said display.
