Enhancement of Application Software for Examination of Differential Magnification Methods and Magnification Interface Factors
The variable visual acuity nature of human vision across fovea and periphery prompted the need to study the differential magnification method as compared with the traditional linear magnification. With differential magnification, outer-area objects were magnified at a level higher than the inner-area objects. An application software was specially developed by the authors previously for the exam...

متن کاملEvaluation of differential magnification during brain SPECT acquisition.
OBJECTIVE We developed a modification of the acquisition zoom technique, referred to as differential magnification (DM), to improve the pixel resolution with fanbeam collimators. This study evaluated the effects of DM on brain SPECT image quality. METHODS SPECT imaging was performed using a triple-head camera with and without DM for a line source in air, Jaszczak and Hoffman phantoms, and 15 ...
متن کاملImpact of Digital Panoramic Radiograph Magnification on Vertical Measurement Accuracy
Objectives. The purpose of this panoramic radiography study was to assess the impact of image magnification on the accuracy of vertical measurements in the posterior mandible. Methods. Six dental implants, inserted in the posterior segments of a resin model, were used as reference objects. Two observers performed implant length measurements using a proprietary viewer with two preset image magni...
متن کاملThe Differential Magnification of High- Redshift Ultraluminous Infrared Galaxies
The spectral energy distribution (SED) of an ultraluminous infrared galaxy (ULIRG) at wavelengths between about 10 and 1000μm is dominated by the thermal emission from interstellar dust, which is heated by absorbing blue and ultraviolet light from young stars and/or an active galactic nucleus (AGN). Midand far-IR radiation from galaxies at redshifts z <∼ 1 has been detected directly by the IRAS...
