文摘
- •
A local structure orientation descriptor for multimodal registration is proposed.
- •
Intra-image similarity is used to describe local structure in high dimensional space.
- •
Normalized similarity distance vector is derived to extract structure orientation.
- •
The method shows credible performance to register liver US and MR images.
- •
It is useful for improve the clinical practicability of US fusion imaging.
