INTRODUCTION TO ULTRASOUND

Sound wave, frequency (>20 KHz)A longitudnal waveUltrasound imaging uses pulse-echo technique.

USES OF ULTRASOUND IMAGING

• Used widely by radiologists to detect tumors and abnormalities.

• Neonatal imaging

EXISTING SYSTEM vs. SYSTEM BEING DEVELOPED

Existing- no proper clarity as such

- hence misinterpretations often

- miss critical disease condition Proposed system-

- proper clarity

- segmentation added

- hence, easy diagnosis

REQUIREMENT ANALYSIS

Hardware Requirements Software Requirements-2 GB hard disk MATLAB (version:7.5.0.342)-Any Intel or AMD x86 processor Field II-160 MHz processor speed -1024 Mb RAM-OS- Windows XP

PROJECT PLANNING

Simulation of ultrasound image by FIELD IIUsing Digital Imaging Processing toolbox of

MATLABImproving noise performance of ultrasound

ADVANTAGE• Better contrast

• Better Resolution

• Better pathology visibility

• Rough estimation of tumor size
