Essay on PACS (Picture Archiving Communication Systems)

Abstract
Picture Archiving and Communication Systems (PACS) is a concept perceived in the early 1980s by the radiology community as a future method of practicing radiology. This Study shows how the implementation of PACS can help remove the problems faced by the radiologists. Following chapters will discuss the details of PACS and how it effects the working, Advantages, disadvantages of PACS. Devices and technology used major problems in its implementation and how can we remove it.

Introduction

Radiology is the branch of medical science dealing with the medical use of x-ray machines or other such radiation devices. It is also the examination of the inner structure of opaque objects using X rays or other penetrating radiation.

As a medical specialty, radiology can be classified into two subfields. Diagnostic radiology is concerned with the use of various imaging modalities to aid in the diagnosis of disease. Interventional radiology uses these imaging modalities to guide minimally invasive surgical procedures.

Radiation therapy uses radiation to treat diseases such as cancer. While originally encompassed within radiology, therapeutic radiology -- or, as it is now called, radiation oncology -- is now a separate field.

Diagnostic radiology
Commonly used imaging modalities include plain radiography, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear imaging techniques. Each of these modalities has strengths and limitations which dictate its use in diagnosis.
X-rays

Radiographs are often used to for quick evaluation of bony structures. Fluoroscopy, angiography and barium contrast studies are special applications of X-ray imaging, where an X-ray video camera allows the imaging of structures in motion or augmented with a contrast agent. Often, chemicals are injected, swallowed or otherwise administered into the body of the patient to help delineate certain parts of the body such as the blood vessels and gastrointestinal tract....................
