  CyberKnife® Stereotactic Radiosurgery System - Washington, DC
Two years after its installation, Georgetown’s CyberKnife continues to prove its mettle and versatility in battling hard-to-treat tumors and lesions.
While two-thirds of cases involve the central nervous system – the original focus for the stereotactic radiosurgical device – Georgetown’s physicians and researchers are also among the most experienced in the world at using CyberKnife to ablate soft-tissue tumors, treating more than 50 lung, pancreas and liver lesions to date.
But because such tumors may move with the patient’s every breath, they pose special operational challenges.

 Encyclopedia of Laser Physics and Technology - pulsed laser deposition, PLD
Within an ultrahigh vacuum chamber, a solid (typically ceramic) target is illuminated with short high-energy laser pulses, which ablate some material via thermal or non-thermal processes.
The ablated material is deposited on a substrate as a thin films of amorphous or crystalline material.
The number of laser pulses is adjusted to obtain the required material thickness.

 The Philosophy of Neuroscience
However, localization arguments for these other functions invariably include studies using animal models.
With an animal model, one can perform careful behavioral measures in highly controlled settings, then ablate specific areas of neural tissue (or use a variety of other techniques to block or enhance activity in these areas) and remeasure performance on the same behavioral tests.
But since we lack an animal model for (human) language production and comprehension, this additional evidence isn't available to the neurologist or neurolinguist.
