Cynthia Landberg: Hi I am Cynthia Landberg and I run the X-ray Systems Laboratory here at GE Global Research.  Welcome to our lab, come on in. In here we have our interventional lab and what you are looking at right now is one of the latest GE Interventional x-ray Tube.  And the x-ray tube actually had its first commercial development here at GE Global Research by one of our founding fathers Coolidge.  And this isn’t too far from what Coolidge developed back in the early 1900s, but just a lot of more power and a lot better image quality and back here is the latest and the greatest out of GE Global Researches are digital detector and what this is, it’s the 40 x 40 cm detector that’s capable of reading out at 30 frames a second to reform these interventional procedures.  So for example, if you go in to a catheterization lab and have a stent placed or go in and have liver biopsy done, this will be done on of these systems with one of these large detectors.  And what we are doing here is looking at ways to even further improve image quality by lowering dose as well as by doing 3D application.  And so what you see right here is this rotating stage, so instead of rotating around our souvenir detector what we do is we rotate around our imaging phantom and right here on our detector, you will see there is a little penny and what that’s used for is to do a calibration of the detector.  So it acts as a little fiducial for us to know exactly where in space we are and know we have had that there as a little household.  So that’s out little trick in how to better use penny in our lab.  And next door, we are doing even more 3D research, so in here it’s kind of a dirty lab where we do a lot of research.  And over in this lab, it’s one of our latest prototypes that we have just built.  This prototype is one of two, the first one was installed at the University of Michigan just recently and this prototype is slated to go to the University of Kansas very soon.  And what it does is it takes 3D breast images, so mammography, which is breast imaging, and traditionally been a 2D imaging modality and what happens in mammography is the woman would come in and this is used to simulate the breast and have a 2D image taken.  Well when you are trying to take a 2D image of something that’s 3D, you need to try and spread it out to make it 2D, which is why this right here is a compression slide.  It’s very uncomfortable procedure for women and it’s not very effective especially in women with denser tissue because it’s hard to see all the overlapping tissue.  So what we are doing is using CT like application, we are trying to get 3D imaging.  So up inside here is our tube and as the tube rotates around, it gives us an arc of about 60 degrees imaging and that 60 degree imaging is enough to give us a little bit of resolution in the depth plane to pull out the overlapping tissue.  So if you have a very small breast cancer hiding amongst all the tissue in the breast, you can easily pull that out and find breast cancer sooner and it’s kind of pulled in very nicely with the whole idea that GE now has a healthcare we imagine.  So it’s a really comprehensive care here that we are looking at folding in and not only looking at our one modality, but the whole encompassing treatment of breast cancer.  My name Cynthia Landberg and I am a physicist in the X-ray Systems Laboratory.  I think the greatest thing about what we do is being able to save people’s lives, it really gives meaning to what we do.  There is nothing like knowing that some piece of equipment that you built was able to find a cancer in somebody such that the that you built was able to find a cancer in somebody such that the
