One hundred and twenty-two years ago German physics professor Wilhelm Conrad Roentgen discovered the power of X-rays with the “X” signifying “unknown”. The hand on left on the image below is the first X-ray “radiograph” that Roentgen created of his wife’s hand in 1895. In today’s modern society it’s easy to take things for granted but prior to the invention of X-Ray machines, broken bones, tumors, or the location of shrapnel were all diagnosed by physical examination. Yikes! Exams involved guess-work, were prone to error, and were dangerous to the patient. I am grateful to live in today’s world of modern medicine where physicians have improved tools to diagnose and help treat illness and trauma without as much guesswork.
