Contrast resolution is the ability to distinguish between features or objects based on density or attenuation properties.
As a result, the contrast resolution of the microscope depends on the incident light intensity.
It is seen when the selected voxel resolution of the scan is greater than the spatial or contrast resolution of the object to be imaged.
This advantage is due to the fact that the contrast resolution in CT scans can be manipulated by a technician during an examination.
NeuroLogica's CT post reconstruction filter was designed to work similar to military synthetic aperture radar systems which attempt to filter out noise while preserving signal quality to thus "see" objects with better contrast resolution. Historically, these types of algorithms are computationally intensive.
Toshiba's new 3LCD projector model offers 3,000 lumens of brightness, XGA resolution, 600:1 contrast resolution, and innovative features in a lightweight and compact design.
The development of the Quantum Detector technology platform made it possible to produce the industry's thinnest detector elements at 0.5 mm with the industry's best low contrast resolution. In addition, this completely new system is equipped with innovative features including an exam table that accommodates up to 660 lbs and coneXact dynamic volume CT reconstruction.
Multislice spiral CT and cone-beam spiral CT scanning, spatial and low contrast resolution and sampling in the Z-direction also are discussed in depth.
"But for breast cancer patients, digital mammography offers a much higher contrast resolution.
For example, some advantages of MRI over sonography include a larger field of view, higher spatial resolution, better contrast resolution, and better capability to assess fibroids for vascularity and classify them by their exact location, said Paul Nikolaidis, M.D., of the department of radiology at Northwestern Memorial Hospital and Northwestern University, Chicago.
Reportedly provides high contrast resolution at higher viewing angles than provided by any other x-ray system currently available.
In addition, DM provides better contrast resolution, distinguishing better than film mammography between different shades of gray.
