This is Implementation Of Zoom Fft In Ultrasonic Blood Flow Analysis short report about Implementation of Zoom FFT in Ultrasonic Blood Flow Analysis. 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. Zoom-FFT technique is simple and affordable to detect the blood clots and other diseases.

This is one of the geographic expeditions 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 report, 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.

Blood flow analysis is done by passing a  high  frequency ultrasonic wave in the blood vessels through a transmitter. The reflected 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.

In Zoom FFT technique 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.

This project report proposes the Study of Bio-medical signal processing, Mixing down the input signal to the baseband frequency using Hilbert Transform, Finding the down sampling using the decimation process, Obtaining the spectrum output using fast Fourier transform, Simulation is done by Mat lab/C, TMS320C5X/6X DSP processor does the real-time implementation.

Conclusion:

Currently, the  report has been tested on the simulation basis, the output of the simulations are satisfactory. Real-time experimentation is being done, using the Piezo electric ultrasonic transducer for verification purpose. The frequencies content from the media are obtained and currently, they are being transformed to image as 2D for visual perception.

This is a BIO Medical Engineering Project Report On Magic Monitor which produced by Biomedical Engineering Department. This project report consists of ten chapters. This Project, “MAGIC ICU Monitor”, is made to measure and observe different Vital signs using various electronic components.

In an addition to diagnosing some cardiovascular diseases by analyzing the data is being measured.

The aim of this advance ICU monitor is to give physicians in the ICU a pre-idea about the diagnosis of the case and suggested emergency required. This project measure blood pressure, pulse ox meter, human body temperature and detect ECG signal and display all these parameters.

There are 4 basic stages in this project which are the Hardware circuit’s stage, the software stage, display stage and finally new technology stage.

The introduction part of the Project mainly consists of 5 separate hardware circuits which are as follows:

1.         ECG Monitoring

2.         Pressure Monitoring

3.         Pulse ox meter

4.         Temperature Monitoring

5.         Serial Interface

The report also explains the details of the mobile interface which display monitor data on PC and define the process of input data for reading and display. The concept mobile technology contains system data flow which provides the details of client-server and HTTP protocol. The report explains the details of software and domain requirement specification.

Conclusion:

In this Engineering Project, the development of intensive care units made the care for more seriously sick patients possible. It allowed utilizing more technically oriented tools to monitor and get information instantly about any changes in the patient’s physiological parameters and developed new strategies to save a life.

On the other hand, it raised ethical and professional issues related to some patients who had untreatable medical conditions or those who sustained unsalvageable damage to their vital organs. The diagrams, flowcharts, and tables provide the complete idea about the MAGIC MONITOR, which helps to understand the concept clearly.
