X-Ray

Radiography

it would be quite easy to joke about this question but that would be lame. my brother is an x ray technician and in his opinion modern x ray machines are essential though i believe that the way to examine a person if they had broken their legs arms etc would be to ask them if they can move them. then feel for any abnormalities.

Yes it's x-ray. But the energy is lower than in the "rest of body" x-ray.

On many patients xrays are performed on a daily basis when in the hospital. When a critical patient comes to a hospital, often multiple chest xrays are taken within hours. The real answer is that there is little issue with taking xrays, the problem occurs when it is done much much more frequently.

X rays were invented by the mountain Monkes of Nepal, whom used a barley leaf to xray Buddahs Body.

The first semi-specialized dental x-ray machine in America was made by the Victor Electric Company out of Chicago in 1913. Victor first advertised the unit in the April 1913 edition of Oral Hygiene. Victor later merged with GE. The unit was a modified medical x-ray. The first specialized dental x-ray was produced by the the Edwards Instrument Company out of Indianapolis. The Edwards unit may even predate the Victor x-ray but I haven't been able to confirm it. Edwards Instrument became Edwards X-Ray Corp in 1919.

The Vulcan Coil Company based in L.A. had a specialized unit in 1915. Several manufacturers followed by 1916.

what is apicopleural in the lung

yes, if the doctors are careful, they will find it, there is probably no other way to pinpoint the location of it either

kvp- peak kilovoltage controls the radiographic contrast of an x-ray image. on some x-ray machines (older ones) the kvp's have to be manually set according to the measurements of the subject being x-rayed, in order for the x-ray to come out right.

Certain brain changes occur with habitual canabis use which will show up on MRI. They are similar to changes seen in scitsophrenics so its worth admitting your habit before having the scan to prevent ending up in a pyschiatric unit!

An arthrogram is an x-ray of a joint with contrast.

Purpose of a bone scan:

1. to detect broken, damaged, or fractured bone that might not be seen using x- rays

2. to detect bone cancer or detect if cancer from another part of the body has spread to the bones

3. to help discover where and why you have pain in the bones

plastic surgeons use it to create images of what the person will look like after their surgery. it is also used in x-rays

The atmosphere does not filter X-rays. It does filter ultraviolet radiation, in the ozone layer.

The voltage of X-rays used for security checks and the routine duration of exposure does not alter cooked food, raw food or standard food packaging materials such as paper, plastic or metal foil in any way.

X-Rays are high energy photons, similar to light, but not visible to the human eye. These photons mostly pass through soft tissue, and are mostly absorbed by metals and semimetals. Therefore, the calcium of your bones absorbs much more of the X-Radiation than does your blood or other tissues.

The "Plate" is a transparent plastic sheet with chemicals on it. The chemicals turn dark when exposed to X-Radiation, which provides a negative image on the film. The chemicals are neutralized and fixed on the transparent plastic with other chemicals. This leaves the technician with the "Film", which is hung up on light boxes to highlight the image.

Often, a broken bone is obvious (a jagged line through an otherwise clean white bone), but sometimes a doctor uses their expert knowledge of physiology to detect less obvious fractures or connective tissue tears that may only look like shadows to the untrained eye.

Note that X-Radiation is ionizing. It is lower energy than nuclear radiation, but there are still limits to exposure. Often, a lead blanket will be used over parts of your body that may be exposed but shouldn't be, and the doctor or nurse will shield themselves to prevent daily, multiple exposures.

That being said, a couple of X-Rays in a year (dental, broken arm) are considered safe. Everyone is exposed to radiation all the time from the sun, natural water supplies, etc. It's only radiation in excess of what our bodies can process which is a problem.

o.o1 nanometers < wavelength <0.06 nanometers, which corresponds to energies of 20 to 100 keV

Some can. It depends on the nature and recency of the conviction.

yes it does show on a x-ray

so they know if the patients digestive system is working properly

X-rays help provide doctor with knowing if we have anything wrong. also if it wasn't for the invention of the x ray by Wilhelm Rontgen then doctors would just have to guess

X-rays were discovered. They've always been around. But since their discovery, we've invented ways to create and then apply them to do stuff.

it was invented in 1895

Because a radiographer knows how to protect themselves from the harmful effects of radiation, by standing far from the beam and restricting the x-ray just to the area of interest, there is no set limit of how many x-rays can be taken in one day. Radiographers wear dosimeters which measure the level of radiation they are receiving on a regular basis, to ensure that they are not getting too high a dose of radiation.
