EE Graduate Seminar

From Proton to Image: A Signal Processing Aspect of MRI

Albert Kir
PhD (EE) Student, CSEE Dept/UMBC

11:30am-12:45pm Friday, 20 April 2012, ITE 237

Magnetic Resonance Imaging (MRI) is routinely used in clinical setting for its great diagnosis and prognosis ability, and is a heavily studied research area across multiple disciplines. MRI has its tie with signal and imaging processing community since it stemmed from the study of nuclear magnetic resonance (NMR). The technique of Fourier imaging makes MRI possible through manipulation of the NMR signals. The issue of imaging speed has always been at the heart of functional MRI (fMRI) and interventional imaging, where a high image frame rate is required or preferable. In the past decade, partly owing to the advance in imaging hardware, a wide range of image reconstruction algorithms have been developed to accelerate the image acquisition process. There has been SENSE, SMASH, GRAPPA, and many of their variations in the parallel imaging category from the early days to the current K-T techniques based on compressive sensing (CS). In this talk, the basic imaging principle for MRI will first be presented, and then a discussion of the first parallel imaging technique, SENSE, will be given. Lastly, the use of K-T FOCUSS on fMRI will be demonstrated.

Albert Kir received the BS degree in Computer Engineering n 2005 and the MSEE degree in 2009 from UMBC. He is currently a PhD (EE) student at UMBC. Mr. Kirs current research interest includes optimization of rapid imaging techniques for structural and functional images for MRI.

The Retriever Weekly talked to UMBC alumnus Delali Dzirasa (CE, '04) about what it takes to be a successful entrepreneur. Dzirasa, the founder of Fearless Solutions, LLC–a team of software engineers and web developers that help clients solve problems through Data Visualization, Web Application Development, Software Engineering, and Rapid Prototyping–knows from experience. Here's what he had to say:

" Dzirasa of Fearless Solutions told stories of how he used to run a barbershop when he lived on the UMBC campus to make money.

"I am a serial starter of things," he said. "My advice for you is to believe in yourself… Never give up and hold onto your vision." "

What should be in the curriculum for a computer science undergraduate program in the next decade? What knowledge and skills should every CS major learn? What learning objectives should we set? How can we ensure that the field remains focused on the disciplinary core while embracing an outward-looking view that actively seeks to work with and integrate into other disciplines such as Biology, Engineering, linguistics and Sociology.

About every ten years the ACM and IEEE Computer Society jointly sponsor the development of a Computing Curricula volume on Computer Science. Their joint task force has just released a Strawman draft of the the CS2013 report and invites comments from a diverse audience with the goal of broadening participation in computer science. The report seeks to be international in scope and to offer curricular and pedagogical guidance applicable to a wide range of institutions.

Computer Science and Computer Engineering students interested in becoming part of the renowned Johns Hopkins University Applied Physics Lab are in luck. The lab is currently seeking interns for this summer.

Located in Laurel, Maryland, the Johns Hopkins Applied Physics Laboratory works on over 600 programs focused on protecting homeland security and advancing the nation’s goals in research and space science, says the lab’s website. Boasting a staff of 4,700, the lab has an annual funding level of nearly $980 million.

Interns will help develop a prototype immersive, distributed, web-application with the goal of putting together an entire virtual environment. The project will require skills like archival data structures, visualization tools, and distributed access.

Interns should have programming knowledge in Java, C++, and C#/00 Programming languages: Java Script, AJAX. In addition, interns should have experience with Apache, Tomcat, Glassfish, or similar web application servers.

Computer Science alumnus Joshua Barczak (B.S. ’03, M.S. ’06) will be a featured speaker at this year’s Undergraduate Research and Creative Achievement Day (URCAD).

Now a Senior Graphics Engineer at the Maryland-based game development studio Firaxis Games, Joshua studied computer graphics at UMBC and carried out research under professors Dr. Marie desJardins and Dr. Marc Olano before graduating with his Master's degree in Computer Science in 2006.

At Firaxis, Joshua’s first game credit was for Sid Meier’s Civilization V video game. For the game, Joshua worked on implementing the rendering framework which drives the diplomacy screens. He also put together a procedural ice-floe generator. “If you’re playing the game and happen to go close enough to the poles, you’ll notice that each and every ice chunk is unique,” writes Joshua on his website.

Joshua will speak on Wednesday, April 25 at 12:00 p.m. in the University Center 312. After Joshua's talk, come chat with him about what it's like to work in the video game industry in the Information Technology/ Engineering (ITE) Building 325B from 3:00-3:50 p.m.

For more information about Joshua’s game development experience, check out his bio on UMBC’s Office of Undergraduate Education website.

We've starting to see advertisements for a new kind of position: privacy engineer.

If you've seen the classic movie, The Graduate, you'll remember the conversation that recent college graduate Benjamin Braddock has with a friend of his father, who says "I just want to say one word to you. Just one word. … Are you listening? … Plastics.". Today, 45 years later, that one word might be Privacy.

Our lives are increasingly being lived online through social media systems, cloud based services, smart phones and other ubiquitous computing and sensing devices. Your smart phone, it's common to hear, knows more about you than your spouse or Mom. Data about us is being collected minute by minute, aggregated, integrated, analyzed, bought and sold.  At the same time, we have develped powerful new datamining and machine learning techniques that, together with parallel computing, can  extract surprising amounts of information and knowledge from the data. 

This data can be put to good uses, such as providing you with better services, but can also result in a loss of privacy. Businesses and other organizations want to avoid a backlash in which they lose customers concerned about their privacy. We've seen recent ads for privacy engineers, such as these from Apple , Google and Intel. This is just a sample, many more exist, although the job title may be different.

The job of a privacy engineer doesn't yet have a well defined consensus description, but the focus is on designing an organization's information privacy policy and helping to ensure that it is accurately described and enforced.  High level tasks include (i) protecting data from unauthorized access, use or disclosure (ii) providing users with appropriate tools to both understand and control what information is collected and how it is shared and used; and (iii) recognizing how the data can be usefully mined without revealing private information.

What courses can a UMBC undergraduate take to prepare for positions like these? After getting a good grounding in the required computer science or computer engineering courses, undergrads can take classes in the fundamentals of security (CMSC 426 and CMSC 487), information assurance (CMSC 444), and cryptography (CMSC 443), take a course in databases (CMSC 461),  datamining and machine learning (CMSC 478) and/or visualization (CMSC 436), and perhaps mobile computing (CMSC 628). Interested students should also look for special topics course, like Security and Privacy in a Mobile Social World which is being offered this semester.  We also have several research labs that work in privacy-related areas, including the Cyber Defense, Coral, Ebiquity, Diadic and Maple labs.
