Why does CT have a better ability to visualize low contrast resolution than XRay?

As CT can identify structures that have physical density differences less than 1%. On the other hand X ray films can identify structures having density difference of about 10%.

Do CT scans provide a much higher resolution of anatomical detail than do MRI scans?
As we know,Clarity of the image is decided by its Spatial Resolution but not by Pixel Resolution. CT have high Spatial Resolution but MRI have comparable Spatial Resolution to CT&far better Contrast Resolution than CT-So,MRI is the BEST to demonstrate Anatomy,especially in parts containing more soft tissue[Eg:Brain]&CT is the BEST to demonstrate Bony Anatomy.
How does a drawing or model help you visualize a problem?
It doesn't always help. Some people are just that way. They learn better by visualizing.
Is higher resolution always better than lower resolution and why?
No, high resolution isn't always better for several reasons. Sensor size is very important- if a manufacturer puts lots of pixels on a small sensor images are susceptible to digital noise that when processed out can cause noticeable smoothing of edges and loss of detail; the bigger the pixels in theory the less noise and better image quality. The 100% crops of an image taken from a high resolution camera will be more noisy than a lower resolution on the same sized sensor. But if zoomed out to show the same amount of picture as the lower resolution picture 100% crop more detail will be shown on the higher resolution picture. a comparison of the 16MP D4 and 36.2MP D800 by digital rev goes over this. In terms of compacts the better quality will be achieved by the lower resolution camera (in RAW). This is highlighted with the lumix cameras with low end models have a higher resolution than the model above them. For example the LX7 a top end compact has only 10MP were as the sz1 has 16 or the Fz45 had a 14MP res then was superseded by the 12MP fz48- to achive higher picture quality. Having said all that new technology such as Nokia's pure view tech does a great job of noise management and cancellation in the 8mp jpegs. But generally the bigger the sensor the better image quality from the same resolution.
Does samsung m620 have a good camera?
No. Definitely not. Mine has a VGA camera (640x480 resolution) and to my knowledge there isn't another version of the phone which has a better camera.
How does the resolution of a 2.4 megapixal digital camera compare with a disposable camera?
Generally speaking, film has a much better resolution than digital cameras. In fact, if you were to compare good 35mm color film to the "megapixel" rating of digital cameras, film would rate in the area of 24 megapixels. The problem is not with the resolution of the storage media (digital vs. film), but rather the abilities of the cameras themselves. A disposable camera is going to have a disposable lens in it. Lenses have a very big impact on the quality of your photos. So, in short, the disposable camera might have a better resolution, but the digital camera will likely have sharper pictures. The operative word here is disposable. Most of the 'disposables' on the market would be better if they were disposed of before taking pictures.
How might the ability to visualize be helpful to you?
The ability to visualize can be helpful in many ways, such as improving memory and comprehension, enhancing problem-solving skills, and fostering creativity and innovation. Visualizing information can make it easier to understand complex concepts and can also aid in achieving goals by creating a clear mental image of desired outcomes.
Which is better Asus 22 inch 1680x1050 resolution or Asus 20 inch 1600 x 900 resolution?
first one: asus 22 inch 1680x1050 res. take into cosideration contrast ratio as well.
Why is books better then television?
Books are far better than tv as with a book you are using your imagination to visualize the scene, but with tv it is already there so your brain doesn't visualize the image.

What is the best contract ratio for tv?
Contrast ratio is the ability of a TV to change contrast on the set. At this point in time (and referring to HDTV's) at least 40:1 or better is probably preferred. I'm sure that'll improve as technology improves.
In TV what is the better contrast ratio- 1000 to 1 or 1500 to 1?
1500:1 is the better contrast ratio
Why do you need to stain specimens?
Staining allows you to better visualize the parts of the tissues.
What words would help readers to better visualize a heavy rain?

Will 720p resolution provide better viewing of the television?
"A 720p resolution would be better than other smaller numbered resolution and is much better than traditional tube televisions. However, a 720p resolution television is not necessarily better or worse than a 1080i. Each is best for different types of viewing."
What resolution is better than 1280x800?
If you are talking about LCD screen, 1280x800 is good resolution but 1366x768 is even better, you can also look for 1400x1050 which is also better than 1280x800. Remember resolution means the number of pixels (dots) per inch, so the better resolution you have the better images or zooming images you will print without losing quality.
Which gives a better measurement for the quality of an LCD monitor the contrast ratio or the dynamic contrast ratio?
The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.
Why the higher resolution always better than lower resolution?
Generally higher resolution is better but three are instances where increased resolution makes no difference. Text based programs tend to use a far lower resolution than is available. Increasing resolution does not increase readability. Also, using a very high resolution monitor to display low resolution graphics will not make the graphics any better resolution. As high resolution graphics demand a lot of processing power, unnecessary resolution can sometimes take processing power away from other more important tasks. So, while there is no need to obtain the lowest resolution systems, beware of spending more money on a high resolution display if you simply don't need it.
