TLDR
The purpose of this study is to enhance previously known calibration methods by introducing a novel calibration fixture and process, which is inexpensive, easy to construct,easy to scan, while yielding more data points per image than previously known designs.Abstract:
Conventional freehand 3D ultrasound (US) is a complex process, involving calibration, scanning, processing, volume reconstruction, and visualization. Prior to calibration, a position sensor is attached to the probe for tagging each image with its position and orientation in space; then calibration process is performed to determine the spatial transformation of the scan plan with respect to the position sensor. Finding this transformation matrix is a critical, but often underrated task in US-guided surgery. The purpose of this study is to enhance previously known calibration methods by introducing a novel calibration fixture and process. The proposed phantom is inexpensive, easy to construct, easy to scan, while yielding more data points per image than previously known designs. The processing phase is semi-automated, allowing for fast processing of a massive amount of data, which in turn increases accuracy by reducing human errors.read more

A review of calibration techniques for freehand 3-D ultrasound systems.
TL;DR: This article is a comprehensive review of what has been published in the field of US probe calibration for 3-D US, covering the topics of tracking technologies, US image acquisition, phantom design, speed of sound issues, feature extraction, least-squares minimization, temporal calibration, calibration evaluation techniques and phantom comparisons.
Patent
Laparoscopic ultrasound robotic surgical system
TL;DR: A LUS robotic surgical system is trained by a surgeon to automatically move a LUS probe in a desired fashion upon command so that the surgeon does not have to do so manually during a minimally invasive surgical procedure as discussed by the authors.
Patent
Tool position and identification indicator displayed in a boundary area of a computer display screen
TL;DR: In this paper, the position and orientation of an out-of-view tool from the viewing area are indicated by the size, color, brightness, or blinking or oscillation frequency of the symbol.
Patent
Medical robotic system with coupled control modes
TL;DR: In this article, a surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled manipulator, to achieve a secondary objective.
Journal ArticleDOI
Three-dimensional ultrasound-guided robotic needle placement: an experimental evaluation.
TL;DR: Clinical use of image‐guided needle placement robots has lagged behind laboratory‐demonstrated robotic capability, and Bridging this gap requires reliable and easy‐to‐use robotic systems.

Beam calibration without a phantom for creating a 3-D freehand ultrasound system.
TL;DR: The calibration method presented in this work does not use a phantom to define in 3-D space the pixel locations in the beam, but is based on the spatial relationship between an optically tracked pointer and a similarly tracked US transducer.
