Abstract

A computer-aided method (30) comprises alternating between one or more of (i) navigational tasks and (ii) measuring, qualification, and quantification tasks of a clinical task in accordance with defined simple click style user interactions. The defined simple click style user interactions are based upon a domain knowledge (34) that includes (i) details of an anatomy and (ii) details of a clinical measurement, quantification, or workflow of the clinical task associated with the anatomy. Responsive to execution of a simple click style user interaction within a current view (36), and further in accordance with a corresponding navigational task or measuring, qualification, or quantification task, the method transitions within the clinical task and its workflow between one or more of (a) a first measurement point and a next measurement point within the current view (36) or (b) the current view (36) and a next view (38).

Claims

1. A computer-aided method comprising:

alternating between one or more of (i) navigational tasks and (ii) measuring, qualification, and quantification tasks of a clinical task in accordance with defined simple click style user interactions, wherein the defined simple click style user interactions are based upon a domain knowledge that includes (i) details of an anatomy and (ii) details of a clinical measurement, quantification, or workflow of the clinical task associated with the anatomy; and

responsive to execution of a simple click style user interaction within a current view, and further in accordance with a corresponding navigational task or measuring, qualification, or quantification task, the method transitions within the clinical task and its workflow between one or more of (a) a first measurement point and a next measurement point within the current view or (b) the current view and a next view.

2. The method of claim 1, wherein each simple click style user interaction comprises an unambiguously defined interaction that is restricted to a given view.

3. The method of claim 1, wherein the current view comprises one or more of a projection image, a slab maximum intensity projection (MIP), a surface rendering, or a volume rendering.

4. The method of claim 1, wherein the current view contains an image rendering of an object upon which a respective simple click style user interaction associated with the current view is defined unambiguously.

5. The method of claim 1, wherein the workflow comprises measuring steps that can be interchanged with view positioning steps, further wherein the measuring steps and view positioning steps each comprise one or more unambiguously defined simple click style user interactions.

6. The method of claim 1, further wherein responsive to the simple click style user interaction, information content within the current view is processed unambiguously for determining a content of the next view.

7. The method of claim 1, wherein an initial current view comprises a default view.

8. The method of claim 1, further comprising:

rendering a first view geometry on a projection plane, wherein the first view geometry comprises one of an initial view geometry or initial view geometries determined as a function of (i) domain knowledge and (ii) volume data provided by an image modality;

alternating between (i) navigational tasks or (ii) measuring, qualification and quantification tasks for the prescribed clinical measurement in connection with (a) the first view geometry or (b) a subsequent view geometry, wherein alternating is in response to a simple click style user interaction with the projection plane;

rendering a subsequent view geometry on a subsequent projection plane further in response to another simple click style user interaction with the projection plane; and

repeating the alternating and rendering of the subsequent view geometry on the subsequent projection plane for a duration of processing according to the requirements of a given clinical task.

9. The method of claim 8, wherein the subsequent view geometry comprises one of an adapted view geometry or adapted view geometries determined as a function of (i) the domain knowledge of the prescribed clinical measurement, (ii) the visualization data, and (iii) one of (a) navigational tasks or (b) measuring, qualification and quantification tasks of the prescribed clinical measurement selected in response to the click-and-go interaction with the projection plane.

10. The method of claim 1, wherein the current view corresponds to a currently available view displayed on a display screen.

11. The method of claim 1, wherein the (i) navigational tasks and (ii) measuring, qualification and quantification tasks include one or more of selecting anatomical landmarks, placing anatomical landmarks, selecting supporting graphics, and placing supporting graphics on the current view.

12. The method of claim 1, further comprising:

implementing the method via an Internet web interface.

13. The method of claim 8, wherein the clinical task comprises an orthopedic measurement for determining an internal rotation of a femoral bone and for quantifying an angle between a femoral neck axis and a femoral condyles axis.

14. The method of claim 13, wherein the first view geometry comprises first and second images of two stack-aligned slices, wherein the first stack-aligned slab is representative of a first elevation level and the second stack-aligned slab is representative of a second elevation level.

15. The method of claim 14, further wherein a first simple click style user interaction comprises a selection of first and second center points in respective ones of the first and second stack-aligned slices, and wherein a subsequent view geometry comprises first or second thumbnail selector views, wherein each of the first and second thumbnail selector views comprises a series of thumbnail images of slabs that are perpendicular to a femoral axis defined by the first and second center points.

16. The method of claim 15, further wherein selecting a desired slab of the first or second thumbnail selector views comprises moving a pointer or position highlighter to be positioned over the desired slab and clicking on the pointer or position highlighter while the pointer or position highlighter is positioned over or highlighting the corresponding thumbnail selector view.

17. The method of claim 1, wherein the simple click style user interaction comprises an interaction with a projection plane and defined as a function of the workflow relative to a current context of the projection plane.

18. The method of claim 1, wherein the simple click style user interaction comprises an interaction with a projection plane and with one or more points of interest within the projection plane, wherein the one or more points of interest have a fixed orientation context, the fixed orientation context being constrained to a given projection plane in which such one or more points of interest were created.

19. The method of claim 1, wherein a current view comprises an image of a slab, and wherein a landmark in the form of a point on the current view represents a line perpendicular to the slab of the current view, and wherein a landmark in the form of a line on the current view represents a plane perpendicular to the slab of the current view.

20. A clinical task apparatus comprising:

a display;

a computer/control unit coupled to the display, wherein the computer/control unit provides data to the display for rendering a projection view; and

an input device coupled to the computer/control unit for providing user inputs to the computer/control unit, wherein the computer control unit is programmed with instructions for carrying out the method featuring simple click style clinical task workflow interactions as claimed in claim 1.

21. A computer program product comprising:

computer readable media having a set of instructions that are executable by a computer for carrying out the method featuring simple click style clinical task workflow interactions of claim 1.
