Apparatus for reference image rotation, and computer software product and method for reference image rotation
First Claim
1. An apparatus for displaying a reference image of a subject, and slices of said subject to be measured in the displayed reference image, for individually positioning two-dimensional slices in preparation for a subsequent slice-by-slice measurement of said subject, comprising:
- a storage device for storing at least one reference image of current patient;
a display screen for displaying the stored reference image as a two-dimensional structure;
an input device for entering commands for displaying and positioning slices of said current patient to be measured, in the displayed reference image;
a processing device connected to said storage device, said display screen and said input device, for processing the commands entered via said input device and for controlling display of said reference image and said slices on said display screen, said processing device, dependent on the commands entered via said input device, generating a perspectively rotated representation of said reference image and a spatial representation, indication corresponding to the perspective rotation of the reference image, of said layers, and causing said perspectively rotated representation to be displayed on said display screen together with said spatial representation indication, said processing device generating a perspectively rotatable frame around said reference image on said display screen as said spatial representation indication, and generating the perspectively rotated representation of said reference image together with said perspectively rotated frame as an at least two-dimensional structure on said screen that is rotated in a same direction as said perspectively rotated representation of said reference image.

Abstract
In an apparatus for displaying reference images of patients and slices to be measured in a displayed reference image for assisting the positioning of slices in preparation for a slice-by-slice measurement and a computer software product and corresponding method, a storage device stores at least one measured reference image of a current patient, a display screen displays a stored reference image, an input device allows entry of commands for displaying and positioning slices to be measured in a displayed reference image, and a processing device processes the entered commands and correspondingly controls the display of the reference image and the slices. The processing device, depending on the entry of commands via the input device by a user, generates a rotated representation of the reference image and a spatial representation—corresponding to the rotation of the reference image—of the slices and displays them on the screen.

8. A computer readable medium encoded with a computer program for operating a processing unit for displaying a reference image of a subject, and two-dimensional slices of said subject to be measured in the displayed reference image, for positioning two-dimensional slices in preparation for a subsequent slice-by-slice measurement of said subject, said processor unit being connected to a storage device for storing at least one reference image of a current patient a display screen for displaying the stored reference image as a two-dimensional structure, and an input device for entering commands for displaying and positioning layers of said current patient to be measured, in the displayed reference image, said computer readable medium encoded with a computer program operating said processing device, for processing the commands entered via said input device and
for controlling display of said reference image and said layers on said display screen, so that said processing device, dependent on the commands entered via said input device, generates a perspectively rotated representation of said reference image and a spatial representation indication, corresponding to the perspective rotation of the reference image, of said layers, and causes said perspectively rotated representation to be displayed on said display screen together with said spatial representation indication and said computer readable medium encoded with a computer program operating said processing device to generate a perspectively rotatable frame around said reference image on said display screen as said spatial representation indication, and to generate said perspectively rotated representation of said reference image together with the perspectively rotated frame as a rotated, at least two-dimensional structure on said display screen that is rotated in a same direction as said perspectively rotated representation of said reference image.

15. A method for displaying a reference image of a subject, and slices of said subject to be measured in the displayed reference image, for positioning two-dimensional slices in preparation for a subsequent slice-by-slice measurement of said subject, comprising the steps of:
-
storing at least one reference image of current patient in a storage device; providing a display screen for displaying the stored reference image as a two-dimensional structure; entering commands for displaying and positioning slices of said current patient to be measured, in the displayed reference image, via an input device; connecting a processing device to said storage device, said display screen and said input device, and processing the commands entered via said input device and for controlling display of said reference image and said layers on said display screen, and in said processing device, dependent on the commands entered via said input device, generating a perspectively rotated representation of said reference image and a spatial representation indication, corresponding to the perspective rotation of the reference image, of said layers, and causing said perspectively rotated representation to be displayed on said display screen together with said spatial representation indication, said processing device generating a perspectively rotatable frame around said reference image on said display screen as said spatial representation indication, and generating said perspectively rotated representation of said reference image together with the perspectively rotated frame as a rotated, at least two-dimensional structure on said display screen that is rotated in a same direction as said perspectively rotated representation of said reference image. - View Dependent Claims (16, 17, 18, 19, 20, 21)
