Chiropractic Spinography and B.J. Palmer's Neurocalometer

Chiropractic spinography is the specialized use of x-rays for spinal analysis, while the neurocalometer was a heat-sensing device developed by B.J. Palmer to locate nerve interference. These tools were central to Palmer's 'upper cervical' chiropractic technique and represent a significant, though controversial, chapter in the profession's history.
