Curved multi-planar reconstruction by using optical fiber shape data

Abstract

A system and method include a shape sensing enabled device (102) having an optical fiber (126). An interpretation module (115) is configured to receive optical signals from the optical fiber within a structure and interpret the optical signals to determine a shape of the device. An image generation module (140) is configured to receive the shape of the device, register the shape with an image volume of the structure and generate a curved multi-planar reconstruction (CMPR) rendering based on the shape.

Description

technical field [0001] The present disclosure relates to medical devices, and more particularly to shape sensing optical fibers for improved multiplanar reconstruction or reconstruction of curved surfaces in medical applications. Background technique [0002] Curved multiplanar reconstruction or reconstruction (CMPR) is a very useful tool in computed tomography (CT) (eg, dental CT, cardiac CT, industrial CT, etc.). Build volumes by stacking axial slices one after the other. CMPR involves generating perspective views of stacks of axial slices, whereby panoramic images and images from paraxial cuts can be generated. CMPR is generally used to visualize structures with curved geometries, such as dental or cardiac features. A CMPR operation involves generating multiplanar reconstruction (MPR) lines on an axial (or coronal or sagittal) plane (eg, in a two-dimensional (2D) view). This can include generating curves along the region of interest. In the 3D modality, the CMPR can b...

Problems solved by technology

Generating path data (eg, curves) for this imaging modality would be a tedious manual task requiring selection of marker points

Although done automatically using image-based centerlines or segmentation algorithms, the task is still difficult
