In March 1896, after hearing of Wilhelm Röntgen's discovery of X-ray and X-ray imaging (radiography), Tesla proceeded to do his own experiments in X-ray imaging, developing a high energy single terminal vacuum tube of his own design that had no target electrode and that worked from the output of the Tesla Coil (the modern term for the phenomenon produced by this device is bremsstrahlung or braking radiation). In his research, Tesla devised several experimental setups to produce X-rays. Tesla held that, with his circuits, the "instrument will ... enable one to generate Roentgen rays of much greater power than obtainable with ordinary apparatus."
What did Tesla begin to research in March 1896? when did tesla begin researching x-ray imaging? What is another term for x-ray imaging? What did Tesla design several experimental setups to produce?  What did Tesla's device work from the output of? When did Tesla start deliberately experimenting with X-ray imaging? What powered Tesla's high energy terminal vacuum tube? What were X-rays known as at the time?
