Alcor has been doing CT scans of some patients for the last few years. When we started the project, we did not know how to properly calibrate the output of the scans. This, along with a mistaken assumption, led to a most unfortunately pessimistic assessment of the degree of cryoprotection of Kim Suozzi, the 23-year victim of brain cancer. Now that Alcor has more experience with CT scan data and has created correct calibration standards, we have re-analyzed that report. It turns out that cryoprotection was vastly better than originally reported.
