Why do medical imaging machines use x-rays instead of visible light?

Because x-rays - as opposed to visible light - can go through fairly thick parts of the body. Useful if you suspect a broken bone for instance.
Visible light will only go through thin parts of your body, like cheeks, earlobes. And will only give a reddish blur at that. Not particularly useful to find out what's going on inside.

How does the electrons microscope work?
An electron microscope use a beam of electrons instead visible light as source of illumination.
Which type of rays are visible?
visible light is the only VISIBLE light.
Why do scientists prefer to talk about a wave model of light instead of saying that light is a wave?
"Visible light" is that part of the electromagnetic spectrum (which includes radio waves, heat, X-rays and Gamma rays) which our eyes can detect. Thus when scientists are talking about "light" they are talking about ALL of the spectrum and when they say "visible light" they are talking about that small bit of the spectrum that we can see.
What is difference between visible and infrared light?
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
How is sunlight composed of energy that is visible to humans and energy that is not visible to humans?
The visible rays of sunlight allows us to see. The other radiations like UV and infrared are not visible.
Application of digital image processing?
gamma img processing,uv imaging,visible imaging,microband wave imaging etc etc
Are all hemorrhoids visible?
Not all of them, they can be visible if they are present near the anus but internal hemorrhoids can occur in the colon that are not readily visible without imaging.
What parts of the electromagnetic spectrum do you use the most?
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
What is eidetic imaging?
Any mental images having unusual vividness and detail, as if actually visible
How can a thermal imaging camera produce a picture in the dark?
it uses infared and heat sensor to make a visible image
Is ther a difference between imaging and infrared imaging?
Not much. Some put the span of the IR spectra at a lightly different place than the thermal span, but the difference is marginal.
What does gross mean in medical terms?
Gross in medical terms means visible with the naked eye.
What is the medical term meaning outer ear?
Auricle is the medical term referring to the visible part of the ear.
Can you see the water on the moon at night if you look in your telescope?
No. The water on the moon is not in the form of liquid water (or even frost) on the surface and is not visible even through a telescope (certain kinds of imaging have detected signs of water, but not at visible wavelengths).
What is a thermal imaging camera?
The prices have been known to be up to $8,000! The minimum is usually around $1,114.000 (at least what i have seen). If you find one under that limit its a bargain. Hope you find yourself a good one :)
What is MRI and how do you explain it?
Magnetic resonance imaging (MRI) is the newest, and perhaps most versatile, medical imaging technology available. Doctors can get highly refined images of the body's interior without surgery, using MRI. By using strong magnets and pulses of radio waves to manipulate the natural magnetic properties in the body, this technique makes better images of organs and soft tissues than those of other scanning technologies. MRI is particularly useful for imaging the brain and spine, as well as the soft tissues of joints and the interior structure of bones. The entire body is visible to the technique, which poses few known health risks.
The Benefits of X-Ray Imaging?
X-ray imaging proves to be beneficial when a person becomes injured, but the injury itself is not visible. People may be unsure of whether or not they broke a bone or merely sprained a ligament. To clear up this uncertainty, doctors often order x-rays on the patient. This kind of imaging allows doctors to examine the patient's bones and check to see if any part of them are broken or if a ligament is sprained.
