Functional Respiratory Imaging (FRI)- A Novel Approach To Assess Lung Health

Respiratory health is deteriorating day by day globally due to an increased exposure to certain risk factors such as pollution, smoking and passive lifestyle. Although in general the respiratory diseases can be kept under control, there is still a need for better phenotyping and management of lung diseases such as COPD and Asthma. The conventional Lung Function Tests like spirometry don’t provide any regional information and have limited sensitivity to detect changes in pulmonary function in an early stage because the healthy areas in the lung compensate for a progressive disease making it undetectable. There is a need to shift to a better technology which can look at the overall lung health.

IamBiomed: Biomedical Engineering Notes Website


 


 

Recently, I came across a effort by Biomedical Engineering students, they are IIIrd yr students in biomedical from watumull institute,Worli,Mumbai. Varun Venkatesh and his friend Aditya ekawade alongwith Prerak Dalal have designed the whole website, I dont know what syllabus they follow but they have indexed Biomedical Engineering notes which is really great.

About IamBiomed

www.iambiomed.com is a website for Biomed people by Biomed people.

We at ‘I am Biomed’ cater to the needs of a Biomedical Student.

636 Biomedical Engineering Project Titles for Discussion

List of projects and titles which i collected from IEEE / WEB / BME mags
BY pragadheeswaran

I HAVE BEEN RECEIVING A LOT OF REQUESTS REGARDING PROJECT IDEAS, KEEPING IN MIND ALL THOSE REQUEST I DECIDED TO PUT IN THIS.

IF YOU ARE INTERESTED IN ANY OF THE PROJECT TITLE BELOW, WE CAN HAVE DISCUSSION REGARDING IT & work on for implementation of that project

LOOKING FORWARD FOR PEOPLE’S RESPONSE TO THESE TITLES N WORKING FURTHER IN BIOMEDICAL RESEARCH PARADIGM

Basic & Detailed Tutorial in CT & MRI for Biomedical Beginners

A extensive tutorial in CT & MRI which will cover all the aspect required by an engineer who has just entered Biomedical Imaging field and wants to explore new avenues of the field

This tutorial will help you in getting familiarized with the operation of CT & MRI

In the first, the terms “CT” (computed tomography) and “CAT” (computer axial tomography; also used: computer assisted tomography) are the usual way to refer to the method involved when x-rays are used to generate the means by which the “target” is examined. (Also in common use is a process connotation: “CATscan“.) When other forms of radiation or waves are involved, specialized terms such as “PET” or “SPECT“, two techniques in emission topography, are applied (some of these are defined by the nature of the signal carrier). Thus, there are many other specialized uses of tomographic techniques, such as in Magnetic Resonance Imaging (MRI), optical tomography, acoustical tomography, and processing of Synthetic Aperture Radar (SAR). As an aside, we now show one example of a geophysical tomography application – specifically, seismic tomography – in which the surface of the subduction zone running south of Japan into the Kurile Islands has been reconstructed from seismic refraction data.

Important to an in-depth understanding of tomography are underlying physics and mathematical operations, which are pertinent to the methods of Signal Processing. This complex subject will not be treated here (an extensive search of the Internet failed to find a good review); intrinsic to some types of tomography are such concepts as image formation, wave transformation, interferometry, and Fast Fourier Transforms.

Three Internet Sites that cover some general aspects of CAT are at: (1), (2), and (3).

We will explain the operating principles by reviewing how a typical CATscan is conducted. As a general statement, the advantage of this and other medical tomographic methods is an improved delineation and differentiation of the various soft tissue organs in humans and other mammals. Thus, x-rays in this mode are usually able to separate these organs discretely, especially when absorbing chemicals (e.g., barium compounds) or dyes are used. We begin by showing a typical CAT Scanner in an examining room:
