Abstract
A technique is provided for extracting one or more features of interest from one or more projection images. The technique includes accessing projection images comprising at least one feature of interest enhanced by a contrast agent, generating a contrast agent null image based on the projection images, generating a bone mask based on the contrast agent null image, and generating a bone extracted image based on the bone mask.
Claims22
A method of extracting one or more features of interest from one or more projection images, the method comprising:
- accessing projection images comprising at least one feature of interest enhanced by a contrast agent;
- generating a contrast agent null image based on the projection images;
- generating a bone mask based on the contrast agent null image, wherein the bone mask only includes an image of bone;
- and
- generating a bone extracted image based on the bone mask.
A method of extracting one or more features of interest from projection images, the method comprising:
- acquiring the projection images of an anatomy of interest by exposing the anatomy of interest to at least two different X-ray energy levels, the anatomy comprising at least one feature of interest administered with a contrast agent;
- generating a contrast agent null image based on the projection images via a material decomposition technique;
- generating a binary bone mask from the contrast agent null image via an automated bone segmentation technique, wherein the binary bone mask only includes an image of bone;
- and
- generating a bone extracted image by comparing an image representation of the anatomy of interest and the binary bone mask.
An image analysis system, comprising:
- a processor configured to access projection images, generate a contrast agent null image based on the projection images, generate a bone mask based on the contrast agent null image, wherein the bone mask only includes an image of bone, and generate a bone extracted image based on the bone mask, wherein the projection images comprise at least one feature of interest enhanced by a contrast agent.
An imaging system, comprising:
- a radiation source and a detector configured to acquire one or more projection images of an imaged volume, the one or more projection images comprising at least one feature of interest enhanced by a contrast agent;
- and
- a processor configured to access the one or more projection images, to generate a contrast agent null image from the one or more projection images, to generate a bone mask from the contrast agent null image, wherein the bone mask only includes an image of bone, and to generate a bone extracted image based on the bone mask.
A tangible, non-transitory computer readable media, comprising:
- code adapted to access one or more projection images, the one or more projection images comprising at least one feature of interest enhance by a contrast agent;
- code adapted to generate a contrast agent null image based on the one or more projection images;
- code adapted to generate a bone mask based on the contrast agent null image, wherein the bone mask only includes an image of bone;
- and
- code adapted to generate a bone extracted image based on the bone mask.
