Generation of a Volume Image of an Elongated Examination Object

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a tomography system that performs scans of elongated objects along different helix-shaped paths. It captures data from multiple scan trajectories, and individually these scan results are incomplete. By combining these incomplete datasets, the system generates a fused dataset that allows for the accurate reconstruction of detailed three- or four-dimensional volume images without certain image artifacts.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical imaging for scanning long parts of the body, such as spine or limbs
• Industrial non-destructive testing of pipes, rods, or cables
• Veterinary imaging for animals with elongated bodies
• Geological or material research requiring high-resolution 3D scans of elongated samples

BenefitsContent extracted from patent full text and abstract with AI.

• Produces high-quality volume images from incomplete individual datasets
• Reduces or eliminates partial revolution artifacts in reconstructed images
• Enables accurate imaging of long or complex objects that may be challenging for conventional tomography
• Supports advanced diagnostic and research capabilities with reliable 3D or 4D spatial information

Patent Abstract

A tomography installation is configured to carry out a first scan along a first helix-segment-shaped trajectory section and to carry out a second scan along a second helix-segment-shaped trajectory section. A first data set is obtained during the first scan, and a second data set is obtained during the second scan. Taken by themselves in each case, both the first data set and the second data set are too incomplete for a reconstruction of a volume image without a partial revolution artifact. From the two data sets, a fused three- or four-dimensional data set is generated that is sufficiently complete for a reconstruction of a volume image without a partial revolution artifact.
