Describe some advantages of digital over traditional X-ray; discuss PACS.

It is obvious to note that the advent of digital technology is rapidly transforming the field of radiological system. As a major drawback on traditional X-ray, this application uses high-energy electromagnetic waves to product a two-dimensional picture on file. If the X-ray encounters bone, which it cannot enter, this appears white on the file. Whatever organ X-ray passes through, appears black on the film. However, digital images have many several advantages over images on film. Firstly, digital X-rays do not have to be developed but are immediately available and can be noticed on any computer screen at anytime, anywhere and by any person. Additionally, because we don’t need film to take digital images, we no longer need to keep developing chemicals in the office, thereby eliminating a potential source of toxic exposure to both patients and staffs. There are no fumes that can escape and permeate carpets, upholstery, clothing and such. At the same time, the elimination of these products cuts costs dramatically. Not only do we no longer have to buy them; we don’t need to hire anyone to safely remove these hazardous materials once used, as there are no materials to be removed. Digital images are typically of higher quality than conventional. They can also be improved through image management. As an important part of digital X-ray, a three-dimensional ultrasonic endoscope has been developed for use in a minimally invasive surgery. It gives a surgeons doing endoscopic a three-way surgery view as opposed to the traditional view of two-way. A PACS (picture archiving and communications system) is define as an idyllic electronic and filmless information system for obtaining, sorting, transporting, storing, and electronically displaying medical images.”  PACs (picture archiving and communication) systems are widely discussed and promoted as the organizational solution to digital image management in a radiology department.  PACS are seen as a step toward high technology integration and more efficient management as compared with conventional system. The use of PACs is to transmit and store digital images and offers new speed in the transmission of digital images. Additional important of PACs is to move images and make the images available to any authorized physicians. It also reduces hospital stays while snowballing the speed of diagnosis.  A new Pac’s improvement is to allow combination of two-dimensional, three-dimensional, and four dimensional diagnostic recording.
