Abstract

In a method for integration of vectorial and/or tensorial measurement data into a representation on a screen of an anatomical image exposure acquired with an imaging medical examination apparatus, upon and/or after selection of, and/or upon and/or after sweeping over, image points of the anatomical representation by means of a screen representation that is associated with at least one control tool operable by a user, the screen representation and/or the speed of movement of the screen representation is varied dependent on the direction information provided by the measurement data.

Claims

1. A method for presenting an anatomic image exposure, composed of image points, to a viewer in a combined presentation with measurement data, comprising the steps of:

in a memory accessible by a computer, storing measurement data defining direction information respectively associated with said image points of said anatomical image exposure, said measurement being selected from the group consisting of vectorial measurement data and tensorial measurement data and being correlated in said memory with said image points;

at a display screen in communication with said computer, displaying a display representation of said anatomical image exposure that embodies display of said measurement data in said display representation correlated with said image points of said anatomical image exposure;

also displaying a screen representation of a manually-operable control tool on said display representation on said display screen and manually operating said control tool to perform an action with said screen representation of said control tool interacting with respective image points of said anatomical image in said display representation exposure, selected from the group consisting of selecting image points of said representation of said anatomical image exposure and sweeping over image points of said representation of said anatomical image exposure; and

at a time selected from the group consisting of upon initiation of said action and after initiation of said action, automatically electronically producing a change, through said computer, in at least one of said screen representation of said control tool and speed of movement of screen representation of said control tool, that represents and corresponds to the direction information defined by the measurement data associated with the respective image points with which the tool interacts in said action, and through said change, imparting said representation of said measurement data, correlated with the respective image points, to a user who is manually operating said control tool to perform said action.

2. A method as claimed in claim 1 comprising employing as said control tool, a control tool selected from the group consisting of a computer mouse, a joystick, and a touch pad.

3. A method as claimed in claim 1 comprising displaying an arrow as said screen representation of said control tool, and wherein the step of varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool comprises varying at least one of a direction and a length of said arrow.

4. A method as claimed in claim 1 comprising displaying a shape-variable icon as said screen representation of said control tool.

5. A method as claimed in claim 1 comprising displaying a multi-dimensional object as said screen representation of said control tool, and wherein the step of automatically electronically varying at least one of said screen representation of said control tool and a speed of movement of said screen representation of said control tool comprises varying at least one of an alignment of said multi-dimensional object on said display screen, a size of said multi-dimensional object on said display screen, and size ratios of respective dimensions of said multi-dimensional object on said display screen.

6. A method as claimed in claim 5 comprising displaying, as said multi-dimensional object, an object selected from the group consisting of an ellipse, an ellipsoid, a circle, a sphere, a rectangle, and a cuboid.

7. A method as claimed in claim 1 comprising displaying, as said screen representation of said control tool, a region of said anatomical image exposure that is associated with said action.

8. A method as claimed in claim 1 wherein the step of varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool comprises varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool dependent on forces selected from the group consisting of forces actually acting on an anatomical region associated with said action, forces virtually acting on an anatomical region associated with said action, forces actually emanating from an anatomical region associated with said action, and forces virtually emanating from an anatomical region associated with said action.

9. A method as claimed in claim 8 comprising varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool dependent on forces occurring in a medical procedure selected from the group consisting of an elastography measurement of tissue in said anatomical image exposure and palpitation of tissue in said anatomical image exposure.

10. A method as claimed in claim 1 wherein the step of varying at least one of said screen representation of said control tool and said speed of movement of said speed representation of said control tool comprises varying said screen representation of said control tool dependent on a location thereof on said display screen.

11. A method as claimed in claim 1 wherein the step of varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool comprises varying said speed of movement of said screen representation of said control tool dependent on a location of said screen representation of said control tool on said display screen.

12. A method as claimed in claim 1 comprising varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool continuously.

13. A method as claimed in claim 1 comprising varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool in steps.

14. A method as claimed in claim 1 wherein the step of varying at least one of said screen representation of said control tool and said speed of movement of said screen representation of said control tool comprises varying said speed of movement of said screen representation of said control tool dependent on a magnitude of measurement data associated with said action.

15. A method as claimed in claim 1 comprising employing as said measurement data, data selected from the group consisting of proton density data, magnetic resonance relaxation times data, data representing flow speed of fluid in said anatomical image exposure, data representing a flow direction of fluid in said anatomical image exposure, data representing the BOLD effect in said anatomical image exposure, data representing a chemical shift in magnetic resonance data of said anatomical image exposure, data representing magnetization transfer in said anatomical image exposure, data representing diffusion in said anatomical image exposure, data representing perfusion in said anatomical image exposure, data representing relaxivity of tissue in said anatomical image exposure, and data representing elasticity of tissue in said anatomical image exposure.

16. A method as claimed in claim 1 comprising acquiring said anatomical image exposure using an imaging modality, as said medical examination imaging apparatus, selected from the group consisting of a magnetic resonance imaging apparatus, a computed tomography apparatus, an x-ray apparatus, an ultrasound apparatus, and an optical camera apparatus.
