Abstract

An image processing apparatus (IP) comprising an input port (IN) for receiving projection data through respective 3D locations in an imaging region, said projection date collected in a scan operation by an imaging apparatus (IM). An image segment generator (IGS) of said apparatus (IP) is configured to generate, based on said projection data, a first image segment for said 3D locations. A visualizer (VIZ) configured to effect displaying said first image segment on a display device before or whilst the image apparatus collects projection data for a different 3D location.

First claim

The invention claimed is:

1. An image processing apparatus, comprising:
an input port for receiving projection data through respective 3D locations in an imaging region, the projection data being collected in a scan operation by an imaging apparatus;
an image segment generator configured to generate, based on the projection data, a first image segment for the 3D locations; and
a visualizer configured to effect displaying the first image segment on a display device before or while projection data for a different 3D location in the imaging region is being received at the input port, the first image segment forming only a partial image of a complete image.

2. The image processing apparatus of claim 1 , wherein the image segment generator operates to generate for different 3D locations a second image segment, said second image segment forming another partial image of the complete image, and the visualizer operates to accumulatively display the second image segment together with the already displayed first image segment.

3. The image processing apparatus of claim 1 , wherein the image segment is an image strip.

4. The image processing apparatus of claim 1 , wherein the image visualizer is configured to compute a display time for a current image segment, said display time being the time delay at which a next segment will be displayed on the monitor.

5. The image processing apparatus of claim 4 , wherein the display time is computed as a function of any of the following: a speed of the scan operation of the imaging apparatus, the measured projection data, the computed image volume segment, a time required to compute the image volume segments.

6. The image processing apparatus of claim 1 , wherein the 3D location is specified in a coordinate system whose symmetry corresponds to a symmetry of a geometry of the scan operation.

7. The image processing apparatus of claim 1 , wherein the imaging apparatus is a slit-scanning imaging apparatus, in particular, a mammography slit-scanning imaging apparatus.

8. A system comprising an image processing apparatus of claim 1 , further comprising the imaging apparatus and/or the displaying device.

9. An image processing method, comprising:
receiving projection data through respective 3D locations in an imaging region, the projection data being collected in a scan operation by an imaging apparatus;
based on the projection data, generating a first image segment for the 3D locations, the first image segment forming only a partial image of a complete image; and
before or while receiving projection data for a different 3D location in the imaging region, displaying the first image segment on a display device.

10. The image processing method of claim 9 , further comprising:
generating for different 3D locations, a second image segment and accumulatively displaying same with the displayed first image segment.

11. The image processing method of claim 9 , wherein the image segment is an image strip.

12. The image processing method of claim 9 , wherein the 3D location is defined in a coordinate system having geometry that corresponds to a geometry of a scan operation.

13. The image processing method of claim 9 , wherein the generating step includes a tomosynthetic reconstruction.

14. A non-transitory computer-readable medium having executable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to perform an image processing method, comprising:
receiving projection data through respective 3D locations in an imaging region, the projection data being collected in a scan operation by an imaging apparatus;
based on the projection data, generating a first image segment for the 3D locations, the first image segment forming only a partial image of a complete image; and
before or while receiving projection data for a different 3D location in the imaging region, displaying the first image segment on a display device.
