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 For example the LX7 a top end compact has only 10MP were as the sz1 has 16 or the Fz45 had a 14MP res then was superseded by the 12MP fz48- to achive higher picture quality.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.
What is the measure of clarity of an image for a microscope?
The measure of clarity for an image in a microscope is typically quantified by the resolution, which refers to the ability of the microscope to distinguish between two closely spaced objects. Higher resolution means better clarity and ability to see fine details in the image. Additionally, factors such as contrast, depth of field, and focus also contribute to the overall clarity of an image in a microscope.
What term describes the ability of an instrument to separate two images that are close together?
Resolution describes the ability of an instrument to separate two images that are close together. Higher resolution allows for better differentiation between the images.
What new feature of the panoramic unit has allowed better resolution to show better details?
The new feature of the panoramic unit that enhances resolution is the implementation of advanced imaging technology, such as high-definition sensors and improved algorithms. These upgrades allow for finer detail capture and clearer images, enabling practitioners to visualize anatomical structures more accurately. Additionally, features like multi-layer imaging and enhanced contrast contribute to improved diagnostic capabilities. Overall, these innovations significantly enhance the quality of panoramic radiographs.
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.
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.
A measure of the clarity of an image?
The measure of the clarity of an image is often described in terms of its resolution, which is the amount of detail that can be seen in the image. Higher resolution images have better clarity as they can display more fine details. Clarity can also be affected by factors such as focus, sharpness, contrast, and noise in the image.
What is angular resolution?
Angular resolution refers to the ability of an optical instrument, such as a telescope or camera, to distinguish between two closely spaced objects in the field of view. It is a measure of the smallest angle between two point sources that can still be resolved as separate entities. Higher angular resolution means better ability to distinguish fine details in an image.
What have scientists learned about substances using the electron microscope?
Scientists have been able to study substances at the atomic and molecular levels using electron microscopes. This has allowed them to better understand the structure and properties of materials, leading to advancements in various fields such as materials science, nanotechnology, and biology. Electron microscopes have revolutionized our ability to visualize and analyze samples at extremely high resolution.

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 Importance of spatial resolution in remote sensing?
Spatial resolution in remote sensing refers to the level of detail captured in an image. A higher spatial resolution means better ability to distinguish features on the Earth's surface, allowing for more precise identification and analysis of objects. This is essential for applications such as land cover mapping, urban planning, and environmental monitoring.
What is the significance of grating resolution in the field of optical spectroscopy?
Grating resolution is important in optical spectroscopy because it determines the ability to distinguish between different wavelengths of light. A higher grating resolution allows for more precise measurements and better identification of spectral features, leading to more accurate analysis of samples.
