“…For example, a 2-D non-rigid registration algorithm establishes a spatial correspondence between neighboring B-scans using B-splines (Rueckert et al 1999), and is applied for the interpolation of B-scan pixels (Penney et al 2004). A variational interpolation method for reconstructing the volume of interest (VOI) directly from contours segmented from the original freehand B-scans in the pre-processing step was proposed in a research study (Deng et al 2011(Deng et al , 2012. Kernel regression can be applied as a two-step reconstruction algorithm that consists of bin-filling and finding a nonparametric estimation for all of the volume data from the previous sample of sparse data (Chen et al 2014).…”

Two-dimensional ultrasound (US) imaging has been successfully used in clinical applications as a low-cost, portable and non-invasive image modality for more than three decades. Recent advances in computer science and technology illustrate the promise of the 3-D US modality as a medical imaging technique that is comparable to other prevalent modalities and that overcomes certain drawbacks of 2-D US. This systematic review covers freehand 3-D US imaging between 1970 and 2017, highlighting the current trends in research fields, the research methods, the main limitations, the leading researchers, standard assessment criteria and clinical applications. Freehand 3-D US systems are more prevalent in the academic environment, whereas in clinical applications and industrial research, most studies have focused on 3-D US transducers and improvement of hardware performance. This topic is still an interesting active area for researchers, and there remain many unsolved problems to be addressed.

“…This method takes a point cloud with oriented point normals as its input and creates an indicator function (an inside outside table) which it can then use to determine connectivity of input points and extract a 3D model. Other closely related works include (Mullen et al, 2010) and work by Deng in (Deng et al, 2011) which use a variational approach, but either depend on denser samples or completely closed contours as input.…”

Abstract:This work presents a process pipeline that addresses the problem of reconstructing surfaces of underwater structures from stereo images and sonar scans collected with a micro-ROV on the islands of Malta and Gozo. Using a limited sensor load, sonar and small GoPro Hero2 cameras, the micro-ROV is able to explore water systems and gather data. As a preprocess to the reconstruction pipeline, a 3D evidence grid is created by mosaicing horizontal and vertical sonar scans. A volumetric representation is then constructed using a level set method. Fine-scale details from the scene are captured in stereo cameras, and are transformed into point clouds and projected into the volume. A raycasting technique is used to trim the volume in accordance with the projected point clouds, thus reintroducing fine details to the rough sonar-generated model. The resulting volume is surfaced, yielding a final mesh which can be viewed and interacted with for archaeological and educational purposes. Initial results from both steps of the reconstruction pipeline are presented and discussed.
