Hole filling with oriented sticks in ultrasound volume reconstruction

Abstract

Abstract. Volumes reconstructed from tracked planar ultrasound images often contain regions where no information was recorded. Existing interpolation methods introduce image artifacts and tend to be slow in filling large missing regions. Our goal was to develop a computationally efficient method that fills missing regions while adequately preserving image features. We use directional sticks to interpolate between pairs of known opposing voxels in nearby images. We tested our method on 30 volumetric ultrasound scans acquired from human subjects, and compared its performance to that of other published hole-filling methods. Reconstruction accuracy, fidelity, and time were improved compared with other methods.

Design of an Ultrasound-Navigated Prostate Cancer Biopsy System for Nationwide Implementation in Senegal

“…The Public Library for Ultrasound Toolkit (PLUS, (accessed on 8 August 2021)) [ 18 ] is an abstraction layer for hardware devices, e.g., ultrasound scanners, position tracking devices, cameras, and generally any kind of data-streaming device. PLUS provides generic functions for pre-processing, such as the 3D ultrasound volume compounding [ 19 ] and live volume rendering [ 20 ] of tracked ultrasound image streams. PLUS offers complete end-user software applications for spatial and temporal calibration, an essential toolset in clinical translation and system maintenance.…”

Automatic Spine Ultrasound Segmentation for Scoliosis Visualization and Measurement

“…The trained networks were also evaluated in spine curvature measurement on the patient dataset. The segmented ultrasound images of the training dataset were reconstructed in 3dimensional volumes with 1 mm isotropic voxel size using the position tracking information recorded for each frame [22]. The reconstruction was visualized by volume rendering in 3D Slicer and overlaid with the posteroanterior X-ray of the same patients.…”
