Out of Cheese

I saw an article on the EurekAlert RSS feed just now entitled "MDCT ‘unwraps’ Egyptian mummy, clearly revealing face of 3,000 year old man". I was puzzled for a minute, wondering just how a modified discrete cosine transform could unwrap a mummy. Turns out there’s another use of the "MDCT" acronym. I wonder how you’d go about encoding an MP3 with multidetector computed tomography.
