Dr. Rachel Grotheer, Assistant Professor of Mathematics and Computer Science at Goucher College, spoke to our students and faculty about  the mathematics behind medical imaging devices.  Her talk was called, "Can You Reconstruct a Tiger from its Stripes?"   She explained that the medical imaging machines output data that gives us information about one of the properties of the tissue, such as how it scatters light (the “stripes"), which is only part of the whole picture (the “tiger").  Everyone really enjoyed this special seminar!
