Summary

Teleradiology is the digital transmission of medical images across distances from one location, a facility where radiographs are taken but no radiologist is, to another location, a facility where a radiologist is available. As such, teleradiology makes possible the following:

Extract of sample
Medical Digital Image Transmission


Primary-care physicians can gather medical data, including radiographs, of patients and consult with specialists through video-conferencing without the patient actually having to travel. This enables speedy therapy.
Teleradiology, the sending of x-rays, CT scans, or MRIs is a store and forward system in which various hard- and software modules are procured from diverse manufacturers. The key to integrating such a diverse system is to adopt certain standards.
The universally accepted standard for teleradiological applications is the American College of Radiology/National Electrical Manufacturers Association (ACR/NEMA) standard DICOM (Digital Imaging and Communications in Medicine).
The ACR standard covers two basic teleradiology systems - the small matrix system and the large matrix system. Small matrix systems (lower resolution) include computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, nuclear medicine and digital fluorography. According to the standard the small matrix digitalisation (acquisition) systems should produce 500 * 500 pixel * 8 bit images or better and the small matrix display systems should produce 500 * 480 * 8 bit displays or better. Large matrix systems include digitised radiographic films and computed radiography. The digitalised standards are 2000 * 2000 * 12 bit images or better and for display systems 2000 * 2000 * 8 bit displays or better.
All the above standard specifications have serious im ...

Here he explains how science can be divided into three parts: All that can fall within the compass of human understanding, being either, first, the nature of things, as they are in themselves, their relations, and their manner of operation: or, secondly, that which man himself…
