Background

• Use 2D images produced by ultrasound

technology to reconstruct a static 3D

image

• Non-Invasive

• Low Cost (Approximately $1000)

• Freely Available to physicians

Project Description

• The purpose of this project is

to produce a real-time 3D

image of the brachial plexususing existing ultrasound

technology.

•Presently a SonositeMicroMaxx SLA ultrasound

probe is used clinically

Previous Work

• In 1997 BrainLAB

received clearance

to market

VectorVision andCurrently costs

>$150k

• Two Avon High

School robotics teammembers prepared

portions of LabView

Program

“The Tracking Pyramid”

• Orientation of three

spheres accurately

tracks the 3D

location of the

ultrasound probe

versus time

• Construct small

enough to fit onprobe but big

enough for Vision

3D Reconstruction from DICOM

LabVIEW Biomedical Source Code 3.0or Isosurf to render 3D image from 2D

DICOM images


10/14

Cameras and Configuration

• Two Logitech

Webcam Pro 9000

with optical axes

identical and parallelto the ground

•80-20 T-slotted Aluminum Bar


11/14

Configuration Contd.

• Camera support

constructed from

80/20 Inc.Aluminum


12/14

Budget and Expenses

• $1,000 provided by University of

Connecticut School of

Engineering

• Spent $120 on two cameras

• Spent $320 on aluminum

framing

• Expected future costs for

tracking pyramid are minimal


13/14

Forward Movement

• Build tracking device to place on probe (begin

with model)

• Complete LabVIEW program to efficiently

calculated probe position• Test program with input values, then incorporate

camera recognition

•

Include calibration in program to ease future use• Complete LabVIEW program for image

reconstruction, initially with still image then in

real time
