This fun-looking piece of facial equipment & headgear is not for a new sport but rather to keep my head entirely immobile while the procedure (stereotactic radiation, or SRS) is being performed.  This fashionable piece was constructed a few weeks ago when I went down to have an updated MRI (used for planning the procedure), to have a “bite-block” (dental mold) constructed, along with a fancy, net-like structure that was formed to the back of my head.  …  Then, this elaborate gadget, which I’m sure was used during (the) inquisition, was bolted to the table.
