Implementation Of Zoom Fft In Ultrasonic Blood Flow Analysis – Using Tms320c5x/6x(Code Composer) Dsp Processor.

July 20th, 2009 by admin | Posted under Electronics Seminar Topics.

This Electronics Seminar Topic deals with the following:

An adequate blood flow supply is necessary for all organs of the body. Analysis of the blood flow finds its importance in the diagnoses of diseases. There are many techniques for analyzing the blood flow. These techniques are not affordable by the poor people because of their high expense. So we have implemented a technique called Zoom-FFT. This technique is simple and affordable to detect the blood clots and other diseases.

Human with his potential tries to get whichever is unexplored, explored, and till now we are managing and succeeding using some technical ways. In the same way this is one of the explorations made for scanning the intra details of some specific objects using ultrasound named SONOGRAPHY, which is used as an alternative to x-ray photography. In this paper, the method to zoom the image or the scanned data-using zoom FFT has been discussed. It also explains the algorithm to get ZOOM FFT and how it can be obtained via simulation. Real time experimentation and its applications, with basics of ultrasound scanning are also explained. Here a specific application will be dealt i.e., ultrasonic blood flow analyzer using ZOOM FFT.

Blood flow analysis is done by passing a high frequency ultrasonic wave in the blood vessels through a transducer (transmitter) .The reflected signal; from the receiver transducer has a different frequency due to the Doppler principle. This signal is passed to a DSP processor to find the frequency spectrum. Because of the high frequency of the ultrasonic wave, the resolution of the frequency spectrum output will not be good. Therefore we go for advanced Zoom FFT technique, wherein a very small frequency change due to the clot formation can be obtained with a good resolution. It can be used to locate the initial presence of a blood clot. All of these tasks must be achieved with a single DSP chip in order for the system to be both cost-effective and power

efficient and thus widely accepted.

This paper proposes:

1.Study of Bio-medical signal processing

2.Mixing down the input signal to the base band frequency using Hilbert Transform

3. Finding the down sampling using the decimation process

4.Obtaining the spectrum output using fast Fourier transform

5.Simulation is done by Matlab/C.

6.TMS320C5X/6X DSP processor does real time implementation.

BASICS
“SOUND IS A COMPRESSIONAL WAVE” Sounds at frequencies above the audible range, to say above 20 KHz are Ultrasonic wave, in the megahertz range. Above which are supersonic sound.

DOPPLER EFFECT PHENOMENON
A shift in frequency (f) of the wave will be expected due to the source and observers motion relative to each other. If the distance between them is reduced or increased. That shift in frequency depends on the velocity of sound which also depends on density of  the medium, in which it propagates.  When a small object is situated in the path of the sound wave, the wave will be resisted (scattered). A direct measurement of this velocity will provide useful information about the dynamic property of the medium. The Velocity of sound in Blood is 1570 m/s. Perceived velocity is   V’=V-V. In terms of frequency (f), as a velocity dependent factor.
