Problems solved by technology
Although such filleted views can aid in the rapid assessment of ribs, segmentation of individual ribs may be required in a preprocessing step
However, such segmentation can be challenging in itself, e.g. where complex and / or extensive fractures are involved, and, when automatic segmentation fails, can lead to unexpected results
Additionally, rounded corner views may provide unintuitive distorted views and in some cases may even cause artifacts

The invention relates to an image processing device (10) comprising a data input (11) for receiving a 3D diagnostic image and a segmentation unit (12) for segmenting a thoracic cavity, a pelvic cavity, an abdominopelvic cavity or a combination of a thoracic cavity and an abdominopelvic cavity in the 3D diagnostic image and for determining a boundary surface thereof. The device also comprise a surface texture processor (13) for determining a surface texture for the boundary surface by projecting image information from a local neighborhood of the boundary surface in the 3D diagnostic image ontothe boundary surface. The device comprises an output (14) for outputting a visual representation of at least one flat anatomical structure, comprising one or more ribs, a sternum, one or more vertebrae and / or a pelvic bone complex, adjacent to the body cavity by applying and visualizing the surface texture on the boundary surface.
Description
technical field [0001] The invention relates to the field of diagnostic tomographic image processing. More specifically, the present invention relates to an image processing device, a workstation, a method for visualizing at least one flat bone adjacent to a body cavity, and a computer readable storage medium. Background technique [0002] For example in computed tomography (CT), examination of flat anatomical structures curved around a body cavity (eg, flat bones such as ribs surrounding the body cavity) based on diagnostic tomographic images can be very time consuming. For example, for fracture analysis and / or for detection or follow-up of bone metastases, a detailed examination of the rib cage may be required. In rib cage analysis, however, the presence of disease or features of interest can be quite insidious, for example subtle fractures or small metastases may be involved. Furthermore, 24 individual subjects, ie, twelve or so pairs of ribs, may need to be individuall...
