best fit (least squares) of sphere

Hello,

I have point cloud data that is in t,x,y,z format of a hemispherical surface.  What I need to be able to do is calculate the center point and radius of the best fit sphere.  Unfrotunately, I can not simple calculate the distance from a global origin.

Anyone have any suggestions? 

Thanks.
