Motivation: Radiofrequency ablation (RFA) has in recent years become a popular treatment for primary tumors in the breast, kidney, liver, and etc. However, traditional approaches of guidance such as ultrasound and computed tomography (CT) fail to provide satisfactory placement precision. Although MRI guidance offers the ability to evaluate the completeness of the RFA, those procedures that are currently done using MRI are performed under “image guidance” rather than “continuous imaging”. The goal of this research is to build a multi-DOF device for breast biopsy/RFA that is MRI compatible and teleoperated with a haptic interface. We envision a “one-sitting procedure”, whereby identification of tumor boundaries, placement of the needle, assessment of placement accuracy, ablation, and assessment of ablation accuracy can be done in one sitting, without removing the patient from the scanner or disrupting tumor location, as shown in Fig. 1.

List of projects and titles which i collected from IEEE / WEB / BME mags
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
Targeted biopsy, a major advance in prostate cancer diagnostics, was detailed by a UCLA team in the current issue of Urologic Oncology. The new technology fuses MRI with real-time 3D ultrasound, providing an exacting method to obtain biopsy specimens from suspicious areas in the prostate.
The unique fusion method provides a major improvement in the way prostate biopsy is performed since the current biopsy methods were developed in the mid-1980s, according to UCLA professor of urology Dr. Leonard S. Marks, a study author.
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:
Right now, getting an MRI scan means you have be still—and alone—in a gigantic machine. Thanks to some clever researchers though, future fMRI scanners might be double-headed—meaning that you can bring a buddy for simultaneous, cuddle-filled brain scans.
Two heads are better than one—particularly if you’re studying the brain activity underlying social interaction. The problem is that imaging technologies such as MRI have only been able to handle one brain at a time – until now. Ray Lee at Princeton University has developed the world’s first dual-headed fMRI scanner. The innovation allows the simultaneous imaging of the brain activity of two people lying in the same scanner.
