Abstract
A method is for generating image data using a computer tomography device. CT raw data is provided. An initial image is produced from the CT raw data. The initial image is segmented into regions based upon anatomical features. An image mask corresponding to the regions in each case is produced for the initial image, the image mask defining an effective region for a respectively assigned mapping rule. The mapping rules are applied in the effective regions defined by the respective image masks, and the image data is generated based upon the initial image processed via the mapping rules.
Claims19
A method for generating image data using a computer tomography device, comprising:
- providing CT raw data;
- producing an initial image from the CT raw data;
- segmenting the initial image into regions based upon anatomical features;
- producing a respective image mask for the initial image, for each of the regions, each respective image mask defining an effective region for a respectively assigned mapping rule;
- applying respectively assigned mapping rules in respective effective regions defined by respective image masks;
- and
- generating the image data based upon the initial image processed by the mapping rules.
An image generating computer, comprising:
- a controller configured to
- produce an initial image from computed tomography (CT) raw data,
- segment the initial image into regions based upon anatomical features,
- produce a respective image mask for the initial image, for each of the regions, each respective image mask defining an effective region for a respectively assigned mapping rule,
- apply respectively assigned mapping rules in respective effective regions defined by respective image masks, and
- generate the image data based upon the initial image processed by the mapping rules.
