Assignee: KONINKLIJKE PHILIPS N.V.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A medical apparatus comprising:
a memory configured to store machine executable instructions;
a processor configured to control the medical apparatus, wherein execution of the machine executable instructions causes the processor to:
receive a medical image descriptive of a three-dimensional anatomy of a subject (418); and
provide an image segmentation by segmenting the medical image into multiple tissue regions using a model-based segmentation, wherein the model-based segmentation assigns a tissue type to each of the multiple regions, wherein the model-based segmentation has a surface mesh, wherein the model-based segmentation comprises a cortical bone model and wherein the segmentation is corrected by using the tissue type assigned to each of the multiple regions to correct for partial volume effects at boundaries formed by the surface mesh between at least some of the multiple tissue regions; and
reconstruct a pseudo radiographic image using the image segmentation and the tissue type assigned to each of the multiple regions, wherein execution of the machine executable instructions causes the processor to correct the pseudo radiographic image using the cortical bone model by forward simulating the partial volume effect correction of the image segmentation in the pseudo radiographic image.
