acquired via a medical diagnostic modality, whereby a processing only in a region of the entire image of an electronic representation of the image data can be shifted within the entire image by the viewer for better recognition of image details. ## Claims ### Claim 1 A method for image presentation of two-dimensional digital data, comprising the steps of: in a processor, generating an electronically processable representation of an entire image corresponding to two-dimensional digital image data, said representation including a visual representation characteristic selected from the group consisting of gamma correction and grey scale spreading; from said processor, causing said representation of said entire image to be displayed at a display screen by processing said representation with a first degree of said visual presentation characteristic at said display screen that gives said entire image at said display screen a first visual appearance due to said gamma correction or prey scale spreading; via an input unit connected to said processor, designating a region within said entire image, said region having an area contained within a boundary; in said processor, electronically processing digital image data in said region differently from said digital image data representing said entire image with a second degree of said visual presentation characteristic that causes said digital image data in said region to have a second visual appearance at said display screen that differs from said first visual appearance due to said gamma correction or prey scale spreading; and via said input unit, manually shifting said region at said display screen within said entire image to move said region to different locations within said entire image and, in said processor, continually processing different image data contained within said region while said region is being moved within said entire image to continually change said first visual appearance to said second visual appearance as said region moves through said different positions in said entire image at said display screen, causing image data encompassed by said region to always have said second visual appearance. ### Claim 2 An arrangement for image presentation of two-dimensional digital data, comprising: a processor configured to generate an electronically processable representation of an entire image corresponding to two-dimensional digital image data said representation including a visual representation characteristic selected from the group consisting of gamma correction and grey scale spreading; a display unit connected to said processor, said display unit having a display screen and said processor being configured to cause said representation of said entire image to be displayed at said display screen by processing said representation with a first degree of said visual presentation characteristic at said display screen that gives said entire image at said display screen a first visual appearance due to said gamma correction or grey scale spreading; an input unit connected to said processor allowing designation of, a region within said entire image, said region having an area contained within a boundary; said processor being configured to process digital image data in said region differently from said digital image data representing said entire image with a second degree of said visual presentation characteristic that causes said digital image data in said region to have a second visual appearance at said display screen that differs from said first visual appearance due to said gamma correction or prey scale spreading; and said input unit allowing manual shifting of said region at said display screen within said entire image to move said region to different locations within said entire image and, said processor being configured to continually process different image data contained within said region while said region is being shifted within said entire image to continually change said first visual appearance to said second visual appearance as said region moves through said different positions in said entire image at said display screen, causing image data encompassed by said region to always have said second visual appearance. ### Claim 3 (depends on 1) A method as claimed in claim 1 wherein the step of generating and displaying said electronically processable representation comprises generating and displaying an electronically processable representation of an entire image corresponding to two-dimensional digital image data acquired with a medical diagnostic modality. ### Claim 4 (depends on 1) A method as claimed in claim 1 comprising conducting said different electronic processing of said region in a computer, and activating said different electronic processing in said region via a computer mouse connected to the computer, and shifting said region over said entire image by movement of the computer mouse. ### Claim 5 (depends on 1) A method as claimed in claim 1 comprising generating and displaying said electronically processable representation of said entire image with a touch-sensitive image representation device, and shifting said region over said entire image by contact movement on a screen of said touch-sensitive image representation device. ### Claim 6 (depends on 1) A method as claimed in claim 1 comprising determining said area of said region in which said different processing occurs by selecting at least one of a shape of said region and a size of said region. ### Claim 7 (depends on 1) A method as claimed in claim 1 comprising conducting said different processing in said region with a boundary transition between said boundary of said region and a remainder of said region. ### Claim 8 (depends on 1) A method as claimed in claim 1 comprising conducting said different processing in said region with a brightness in said region that is different from a brightness of said remainder of said entire image. ### Claim 9 (depends on 1) A method as claimed in claim 1 comprising conducting said different processing in said region with a contrast in said region that is different from a contrast of said remainder of said entire image. ### Claim 10 (depends on 1) A method as claimed in claim 1 comprising conducting said different processing in said region with a sharpness in said region that is different from a sharpness of said remainder of said entire image. ### Claim 11 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to generate and cause display of said electronically processable representation of an entire image corresponding to two-dimensional digital image data acquired with a medical diagnostic modality. ### Claim 12 (depends on 2) An arrangement as claimed in claim 2 wherein said input unit is a computer mouse that activates said different electronic processing and shifts said region over said entire image by movement of the computer mouse. ### Claim 13 (depends on 2) An arrangement as claimed in claim 2 wherein said input unit comprises a touch-sensitive image representation screen of said computer, allowing shifting said region over said entire image by contact movement on said screen. ### Claim 14 (depends on 2) An arrangement as claimed in claim 2 wherein said input unit allows determination of said area of said region in which said different processing occurs by allowing selection of at least one of a shape of said region and a size of said region. ### Claim 15 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said different processing in said region with a boundary transition between a boundary of said region and a remainder of said region. ### Claim 16 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said different processing in said region with a brightness in said region that is different from a brightness of said remainder of said entire image. ### Claim 17 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said different processing in said region with a contrast in said region that is different from a contrast of said remainder of said entire image. ### Claim 18 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said different processing in said region with a sharpness in said region that is different from a sharpness of said remainder of said entire image. ### Claim 19 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said different processing in said region with a gamma correction in said region that is different from a gamma correction of said remainder of said entire image. ### Claim 20 (depends on 2) An arrangement as claimed in claim 2 wherein said computer is configured to conduct said
