I've just remembered this question I've been dying to ask. What type of film do doctors use to take pictures of people's skeletal structure from the inside?

Large sheets of black and white, I think it's called orthographic or something like that.

Link didn't work. Here's what they are:

CXS Half Speed Blue Film
High contrast, fine grain, blue sensitive Agfa film. For use with blue emitting rare earth screens.
Manufactured by Agfa
CXS Premium X-Ray Film provides maximum image quality for general-purpose radiology. This film is compatible with existing generating equipment, cassettes and screens. CXS Premium X-Ray Film is manufactured by Agfa and is second to none in quality.
CXS Half Speed Blue Film's high contrast and fine grain yields very sharp images. When used in combination with Blue 800 rare-earth screens, it provides up to one-half the patient exposure of high (full) speed blue film used in combination with calcium tungstate screens.
-High contrast, blue sensitive film

X ray (Plain Film)

Overview
X rays are actually electromagnetic waves. When they are passed through your body to a photographic film on the other side, they create a picture of internal body structures called a radiograph.

Chest x rays, which are among the most common imaging tests, can reveal abnormalities of the lungs (such as pneumonia, tumor or fluid), heart (such as congestive heart failure or enlarged heart), and rib cage (such as broken or abnormal bones).

Other common types of x ray examinations include abdominal studies, which can reveal abnormalities of not just the abdomen, but also the liver, spleen, gallbladder, and kidneys; gastrointestinal studies of the upper or lower GI tract; studies of the joints to assess things like arthritis and sports injuries; and mammograms, which can help detect breast cancer with the use of special x ray equipment.

The less dense a structure of the body is, the more radiation passes through it and reaches the film. The x rays expose the film, changing its color after it is developed to gray or black, much like light would darken photographic film.

Bones, as well as tumors, are more dense than soft tissues. They appear white or light on the x ray film because they absorb much of the radiation, leaving the film only slightly exposed. Structures that are less solid than bone, such as skin, fat, muscles, blood vessels, and the lungs, intestines, and other organs, appear darker on the film because they let more of the x rays pass through. Likewise, a break in a bone allows the x ray beams to pass through, so the break appears as a dark line in the otherwise white bone.

To make certain organs stand out more clearly, a "contrast medium"--a substance that blocks x rays rather than transmitting any--can be introduced into the body, in the form of a drink or injection. Barium sulfate is commonly used to study the gastrointestinal tract, while iodine-containing dyes are often used to provide information about the gallbladder, kidneys, blood vessels (using a technique called angiography).

An xray machine is composed of the control panel, a high voltage generator, an xray tube and the table. The high voltage generator steps up the voltage from 440 volts to as much as 150 kilovolts. The control panel is where the operator sets the 3 factors that control the amount of radiation produced. These are amperage (mA) voltage (kV) and time. The table contains a tray mechanism in which a film/screen cassette is inserted to capture the radiation after it passes through the subject being filmed. The xray tube is a piece of glassware with a rotating tungsten target. The high voltage applied across the xray tube causes electrons to collide into the target. The energy creates mostly heat and a small amount of radiation. An xray machine, even one that has been disassembled can still contain high voltage in its internal capacitors. Only a trained serviceman should work on an xray machine. Also, only a trained operator should be allowed to operate the machine because improper operation can result in permanent damage to the xray tube and lethal amounts of radiation that can result in blindness, radiation burns, cancer and death. Finally, any image made by an xray machine is of little value unless it is interpreted by a qualified doctor. A radiologist is a medical doctor (M.D.) who has specialized in looking at and understanding xray images. The best chest xray is useless unless a radiologist looks at it and makes a report on what he/she sees.

I am a dentist. It is called (drum roll) x-ray film. Seriously, that's what it's called. I am ordering some right now.
