Completed Research

The following is a list of recently completed research projects in the Ultrasound Research Laboratory, Laboratory for Enabling Technologies for Medical Ultrasound:

Fourth Generation Portable Ultrasound Scanner

We are in the process of developing the fourth generation of a versatile, mobile ultrasound system, while the third generation system is undergoing clinical testing. Both systems are lightweight self-contained diagnostic ultrasound system, intended for use in a helicopter, an ambulance, at disaster and triage sites and in rural clinics. They are based on the Terason t3000 PC based ultrasound scanner system.

3D Medical Ultrasound Image Segmentation

The goal of this research is to develop a robust automated system for the segmentation (boundary identification) of targets in 3D medical ultrasound images. Target structures include the prostate (cancer), free fluid volumes (such as abdominal bleeding), and cysts and lesions. Accurate and fast segmentation  will allow doctors in the field to visualize 3D models of internal structures and fluid volumes as well as calculate statistics such as shape, volume, or track those statistics over time for a patient, giving the clinician additional diagnostic tools. The work is carried out by John David Quartararo, MS student in Electrical and Computer Engineering.

Performance Metrics for Wireless Image Transmission

In order to assess the expected performance of various wireless data options for the portable ultrasound machine, such as wireless LANs, 3G mobile phones, and satellite phone, a testing protocol must be developed to accurately compare the performance under different options. The ultimate goal is to be able to accurately predict what level of performance can be expected from each data option given a specific application. The work was carried out by Brett Dickson, MS student in Electrical and Computer Engineering.

Quantitative 3D Freehand Ultrasound Imaging by use of Integrated Tracking System

Three-D imaging is widely used in MRI and CT imaging, and is gaining importance in medical ultrasound imaging as well, especially in obstetrics. The goal of the research is to develop a 3D imaging system with a position and orientation tracking sensor build into the transducer housing. This combines the flexibility of freehand 3D ultrasound with the accuracy of 2D matrix array transducer scanning. The work was carried out by Abraham (Bram) Goldsmith, MS student in Electrical and Computer Engineering.

Injury-mimicking Ultrasound Phantoms

Injury mimicking ultrasound phantoms are training devices that can emulate pre- and post-injury conditions at specific regions of human anatomy.  As such, they are likely to be useful tools for teaching medical personnel how to recognize trauma conditions from ultrasound images.  Due to the increased use of portable ultrasound systems, earlier diagnosis of internal trauma will be feasible at locations such as traffic accidents, earthquakes, battlefields and terrorist attacks.

Modeling and Quantitative Ultrasound

The applications of an ultrasound pulse-echo system range from the reliable detection of critical flaws in manufactured parts, to identification of the surface topology of organs or tissues, to object recognition in an ocean environment. The energy optimization method, carried out by then MS student in Electrical and Computer Engineering, Aditya Nadkarni, is used to improve the ability of a pulse-echo system to quantify specific aspects of a reflecting structure or to identify a given reflector geometry.
