Abstract

The invention proposes a technique to determine whether two multimodal image volumes with different field of view coverage are to be registered or not. The technique includes an automatic analysis of a matrix and classifies whether features generated from the matrix are to be registered or not. For instance when an input is two-volume, such as a neuro-station of magnetic resonance imaging (MRI) and lung station of a computed tomography (CT), the invention determines that such volumes do not have an anatomical overlap and are not be registered. The technique determines similarity measure between all slices of volume one and all slices of volume two.

A TECHNIQUE TO DETERMINE REGISTERABILITY OF TWO MULTIMODAL VOLUMES

BRIEF ABSTRACT

The invention proposes a technique to determine whether two multimodal image volumes with different field of view coverage are to be registered or not. The technique includes an automatic analysis of a matrix and classifies whether features generated from the matrix are to be registered or not. For instance when an input is two-volume, such as a neuro-station of magnetic resonance imaging (MRI) and lung station of a computed tomography (CT), the invention determines that such volumes do not have an anatomical overlap and are not be registered. The technique determines similarity measure between all slices of volume one and all slices of volume two.

DETAILED DESCRIPTION

Generally, for any two-image volumes to register, registration algorithm requires both volumes to have same anatomy region. For instance, a lung in a computed tomography (CT) volume and lung in magnetic resonance imaging (MRI) volume with same anatomy region may be registered.

A conventional technique includes registration of two CT volumes with same anatomy region. However, the conventional technique focuses on monomodality for registration of two CT volumes.

Therefore, there is a need for a technique, which focuses on multimodality for registration of two CT volumes.

A technique to determine whether two multimodal image volumes with different field of view coverage are to be registered or not is disclosed. The technique includes an automatic analysis of a matrix and classifies whether features generated from the matrix are to be registered or not. Figure 1 depicts the technique for automatic analysis. For instance, when input is two-volume, neuro-station of magnetic resonance imaging (MRI) and lung station of computed tomography...
