The decomposition into iodine maps and virtual non-contrast images is then performed using a procedure called “three material decomposition”. Please refer to the “technical implementation” chapter on DSCT.COM (http://www.dsct.com/index.php/technical-implementation-of-dual-energy-ct-t-johnson/) for details. Best regards, T.

I am a graduate student undergoing masters in radiology, interested to do a thesis paper on DECT. A basic question, from the raw data that is acquired using DECT, how do we post process them to get the virtual unenhanced and iodine map data? Thank you for entertaining beginners like me! Hello.
