Research has shown that technology is developing rapidly and it can indeed, helps to improve teaching and learning new things when used wisely-and companies have responded in kind, creating hardware, software, and other devices that give teachers innovative ways to engage students, improve retention, and make learning more interactive.

e-Learning Sessions

There are various New Audiovisual systems available that offer sharp images and these new techniques which will improve and heighten a projector’s contrast without sacrificing brightness, and it is very much eco-friendly projectors that eliminate the need for very high costly mercury lamps, are among the many recent developments in audio-visual (AV) technologies with implications for educational institutions
.

Educators Trust projectors for medical imaging and high Officials at the University of North Carolina School of Medicine’s Department of Radiation Oncology make critical treatment decisions based partly on images showing where cancer cells are, so having a crystal-clear projector image is critical for accurate diagnoses.

Julian Rosenman, a professor at the university’s Department of Radiation Oncology, said black-and-white CT scans with shades of gray dispersed throughout could dictate a patient’s treatment. That’s why the department bought two of Canon’s REALiS SX80 Mark II D Multimedia LCOS projectors, which are mounted on the ceiling for stability and offer dual projection images so students and doctors can compare and contrast scans side by sideThe main advantage of canon projectors is that it has a facility to teleconference with medical professionals and also students worldwide because the images can be shared with the doctors at other campuses or at hospitals.

Rosenman stress the importance of accuracy of projected images in tumor boards ans also in telemedicine meetings because doctors view medical images in order to take important decisons in treating the patient and also in comparing medical data.

The Canon REALiS projectors feature 3,000 lumens of brightness and the projection technology called Liquid Crystal on Silicon (LCOS), to achieve ultra-sharp, high-contrast and lattice-free images without the “screen door” effect that can mute the color and detail of some LCD images.The Realis features a mode that complies with Digital Imaging and Communications in Medicine (DICOM) devices which offers 21 levels of grayscale gradation for more accurate diagnoses with out rolling bars or visible beat frequencies.

Early LCOS projectors sacrificed compactness and brightness to achieve this degree of clarity, But the company has developed a new optical system, called aspectual illumination system (AISYS), that solves this problem. AISYS splits beams of light into vertical and horizontal components, then uses each component to enhance brightness or contrast. The result is a system that combines the kind of sharp contrast and high degree of brightness needed to distinguish between many shades of gray. More over schools and colleges are using Casio’s new lineup of Green Slim Projectors, eco-friendly projectors that eliminate the need for mercury lamps that typically must be replaced after 2,000 hours of use.The Green Slim DLP projectors use a patented hybrid “solid state” light source, which combines laser and LED technology to achieve high brightness, instead of a mercury lamp.
