Phototime in xray5/3/2023 This appointment, which began as a 1 year sabbatical leave became a 31-year career.ĭr. ![]() Hodges' remarkable education and experience prepared him well for the leadership role in radiology that he was destined to play. Hodges was recruited in 1919 as a roentgenologist and remained there until 1927 when he became professor and chairman at the University of Chicago. The Rockefeller Foundation through its China Medical Board had made a major commitment to build and operate the Peking Union Medical College. Hodges began practicing radiology in China. After the war, the University of Wisconsin granted Dr. Hodges became a commissioned officer in the army and was stationed at the X-ray School in Camp Greenleaf, GA. Hodges also served as a laboratory assistant to Erlanger and Gasser in their animal experiments aimed at the treatment of surgical shock by the IV injection of sodium arabate to replace lost blood. That work had defied their efforts as long as the only available recording device was the quartz fiber galvanometer, but yielded when they used instead, the electron stream of a Brown tube. He also worked with his medical school roommate, Herbert Gasser, who in 1944 received the Nobel Prize with Joseph Erlanger for measuring and classifying nerve-fiber conduction. degree in 1918 at Washington University in St. Hodges studied physiology at the University of Wisconsin before completing his M.D. ![]() There he learned how to prepare the chemical solutions used in "X-ray photography." At age fourteen, Paul became an apprentice in the hospital, which by that time had been equipped with more powerful X-ray equipment. This device sputtered away in the front office during Paul Hodges' early childhood. Their first X-ray machine used a German induction coil with mechanical interrupter and a small X-ray tube similar to that used by Röntgen. Radiology began to be practiced at Rinehart Hospital in 1897. Paul's father died in 1901 at the early age of 36, due to septicemia from a finger infection acquired while performing an autopsy, and Uncle Will gradually became Paul's surrogate father. William Rinehart, at the Rinehart Hospital in Ashland, WI. He was born, before Röntgen's discovery, on January 6, 1893, the son of a physician who worked in partnership with Paul's uncle, Dr. TL DR - it's a convention used to reduce cognitive loading on radiologists.Paul Hodges is an extraordinary individual. looking upwards to the head.Īnd here's an example of a canine head using the DorsoVentral positioningĪnd you can see that the image is not reversed which I presume is because this is the normal way to read these type of images. But I'm guessing that vets also read DV and VD images of the thorax as though facing the ventral surface.īTW, when taking horizontal or transverse CT slices through the human thorax, the view shown is that from caudal to cranial, i.e. I've noticed some DV images of animals are not switched so that the R is on the left but apparently most are. And that's the way the film is read, from the front. When taking an AP film, the patient is positioned so that the posterior surface is now closest to the film, and the patient's left is on the left of the film. But the sides are switched so you actually read the films as though looking from the anterior side of the patient i.e. So, the right side of the chest appears on the right of the film, and the left side on the left. ![]() So, when you have a PA chest x-ray ( or dorsoventral view for a dog ) the x-rays enter the posterior surface, exit the anterior surface to hit the imaging surface. When reading radiographs in human health, the x-rays are read as though facing the patient.
