Abstract
In a method and an arrangement for image representation of two-dimensional digital image data 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.
Claims20
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.

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.
