X-rays were first discovered by Wilhelm Conrad Roentgen, a German physics professor. Roentgen also studied X-rays and their ability to pass through human tissues to produce images of the bones and metals visible on developed film. To obtain an X-ray image of a part of the body, a patient...

How does a concave mirror form an image? Why does chromatic aberration occur? How do lenses and mirrors affect a ray of light? How does adaptive optics improve the performance of a telescope? How can the resolution be improved in bright field microscopy?
Another way to look at the brain is to use a computerized axial tomography (CT) scan, which takes a series of X-rays of the brain and uses a computer to combine them into an image [source: National Headache Foundation]. Yet another imaging technology is the positron emission tomography (...
However, in this case, since the light rays don't really come from here, we call it a virtual focal point.Concave lenses are used in things like TV projectors to make light rays spread out into the distance. In a flashlight, it's easier to do this job with a mirror, which usually ...
In addition to X-rays, gigantic black holes can also eject materials at high speeds to form jets. Many distant galaxies have been observed with such jets. Currently, scientists think that these galaxies have supermassive black holes (billions of solar masses) at their centers that produce the ...
MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the 927 Words 4 Pages 3 Works Cited Decent Essays Read More Modality Comparison Healthcare has evolved tremendously over the ...
