X-ray phase contrast imaging solves the basic problem of conventional X-ray imaging, i.e. low image contrast arising from small absorption differences.
Approximately 15 years of experimentation, primarily carried out at synchrotron radiation facilities, has demonstrated that such an approach can solve the basic problem of conventional X-ray imaging, i.e., low image contrast due to small absorption differences.
So far, consumers have been reluctant to embrace digital imaging, mainly because of operational complexity, built-in obsolescence and low image quality.
If you can get past the low image quality, you'll get more fun out of this watch than any watch you have owned.
They are difficult to detect on non-contrast CTC images due to low image contrast with surrounding objects.
Unfortunately, its applicability is limited by the relatively low image acquisition speed, typically seconds to minutes per image.
Bright field (BF) optical microscopy is regarded as a poor method to observe unstained biological samples due to intrinsic low image contrast.
In clinical practice, interuser variability, high computational cost and low image quality are always big problems that puzzle the clinical application of computer-aided echocardiographic boundary detection.
In the presence of noise, the 3 point derivative method and Hamming-window parabolic filtration method resulted in the best compromise between low image noise and high spatial resolution.
"Back then, Puma was a loser, a me-too brand, with a low image and lousy performance in the U.S. and the rest of the world," said Thore Ohlsson, a 60-year-old Swedish investor who at the time was chief executive of Aritmos and recommended Mr. Zeitz for the job.
Only 1 of 15 (7%) was in a patient with a low image count density.
