A California neurosurgeon has launched what could turn into an
epic legal battle over the rights to use diffusion tensor imaging,
an MR technology that lately has begun to catch on as a diagnostic
and neurosurgical planning tool.
Claiming that he holds the exclusive license to this technology,
and that all users are violating that license, Dr. Aaron Filler has
filed suit against the Regents of the University of California and
Siemens Healthcare.
