Macintyre's X-Ray Film is an 1896 documentary radiography film directed by Scottish medical doctor John Macintyre. The film shows X-ray images of a frog's knee joint and an X-ray radiograph of an adult's heart and digestive tract (using bismuth as contrast). Each image was captured in 1/300th of a second. Text from the film's title card reads:

Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
Daniel reported that 21 days after taking a picture of Dudley's skull (with an exposure time of one hour), he noticed a bald spot 2 inches (5.1 cm) in diameter on the part of his head nearest the X-ray tube. [20] His discovery prompted physicians to experiment with x-radiation as a method for hair removal - a method that became popular in the ...
On 11 January 1896 he made the first use of X-rays under clinical conditions when he radiographed the hand of an associate, revealing a sterilised needle beneath the surface. [4] A month later on 14 February he took the first radiograph to direct a surgical operation. He also took the first X-ray of the human spine.
[10] [11] Fleischman quickly exhibited a keen interest and became proficient with the various apparatus that were necessary to produce the X-rays. By 1897, one year after the discovery of X-rays by Röntgen, she had established an X-ray laboratory on Sutter Street in San Francisco. [12] There she examined patients on behalf of local physicians.
In early 1896, there was a wave of excitement following Wilhelm Conrad Röntgen's discovery of X-rays on 5 January. During the experiment, Röntgen "found that the Crookes tubes he had been using to study cathode rays emitted a new kind of invisible ray that was capable of penetrating through black paper". [ 9 ]
On January 27, 1896, Wright produced an X-ray photograph, barely a month after Wilhelm Röntgen's seminal paper On A New Kind Of Rays was published on December 28, 1895. This was the first X-ray image produced in the country. [9] He contributed numerous scientific papers, chiefly on astronomical and electrical subjects, to various publications.
