Optimization of Digital Mammography Resolution Using Magnification Technique in Computed Radiography
Purpose: To determine whether magnified digital mammography using a computed radiography system can produce better spatial resolution by reducing the focus-object distance, and to define the optimal magnification factor when a large x-ray tube focal spot is used for digital mammography using a CR system. Materials and Methods: Digital images obtained using computed radiography of a breast phant...
We use the largest sample of z 6 ~ galaxies to date from the first four Hubble Frontier Fields clusters to set constraints on the shape of the z 6 ~ luminosity functions (LFs) to fainter than M 14 AB UV, = mag. We quantify, for the first time, the impact of magnification uncertainties on LF results and thus provide more realistic constraints than other recent work. Our simulations reveal that, ...
Background and study aims There have been few evaluations of the diagnostic ability of new narrow band light observation blue laser imaging (BLI). The present prospective study compared the diagnostic ability of BLI magnification and pit pattern analysis for colorectal polyps. Patients and methods We collected lesions prospectively, and the analysis of images was made by two endoscopists, retro...

Micrograph of a liver biopsy specimen from the patient’s explanted liver showing Clonorchis sinensis in intrahepatic biliary ducts, with labeled structures. A, Intrahepatic bile duct; B, C. sinensis uterus filled with eggs; C, seminal receptacle; D, cecum; E, vitellaria. (Hematoxylin ...
We give a simple general formula for the total angular dispersion due to multiple arbitrary dispersive elements in a series. It is simply the sum of the individual elements' angular dispersions but with each divided by the total spatial magnification afterward (or, equivalently, multiplied by the total angular magnification afterward).
