The primary task for an observer in medical imaging is to decide whether a given patient image shows evidence of pathology, or not. This therefore demands an approach which can identify the observer performance in relation to the diagnostic quality. ROC analysis is widely used in radiology to subjectively assess …

Preparing a local vaccine for viruses that affect the respiratory system is important for all age groups, and the goal is to control the infection and prevent its spread, knowing that many viruses that infect the upper and lower respiratory tract are more than approximately 200 viruses for humans, especially …

The visual grading of the visibility/reproduction of normal anatomy or pathology is a valid and commonly used approach to subjectively quantifying the quality of an image in medical imaging (Seeram, Bushong, Davidson, & Swan, 2014). Its application is based on how clearly the anatomical structures are visualised by an observer, …

This measurement requires an observer to give a subjective response in relation to a physical stimulus’ influence on a test object being imaged. Test objects used in these measurements are usually simple, such as line pair (used to determine the spatial resolution), and discs made with holes of different contrasts …

The term, objective measurements refer to the description of the physical characteristics within the digital radiographic system. They have the ability to describe the performance of the whole imaging system by referring to the image quality. These physical measures include a signal to noise ratio (SNR), contrast to noise ratio …

The new tetradentate Schiff base ligand L 4,4`-(1Z,1`Z)-(5,5-dimethylcyclohexane-1,3-diylidene) bis ( azan-1-yl-1-ylidene) bis (1-phenyl-1H- pyrazol-5 (4H)-one.has been synthesized from condensation of 5 ,5-Dimethyl-cyclohexane-1,3-dione with 5-amino-2-phenyl-2,4-dihydro-pyrazol-3-one. Monomeric complexes with the general formula [M(L) (H2O)2]2Cl where M = Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) are reported. The structures of new ligand, mode …

A luminescent solar concentrator (LSC) was made by mixing two organic dyes; erythrosine and, eosin y then silicon solar cell efficiency was measured before and after synthesizing the luminescent concentrators having the two mixing dyes. Significant improvement was noticed in the solar cell efficiency from (9.03) to (11.24). The best …
