Introduction

           The development of technology and Nuclear Medicine imaging is a conglomeration of many scientific discoveries. This assignment, written as an exercise to learn 'html', discusses some of those innovations that have made a substantial impact on Nuclear Medicine and its future. The emergence of the basic components of the computer rapidly accelerated the progress of technological advances in medical imaging.

One of the most pivotal inventions of the century,the transistor, was invented by Bill Shockley at Bell Laboratories in 1947. Smaller, faster, cheaper, and more reliable than the vacuum tube, the transistor also generated much less heat.1  They therefore did not attract moths, which had always short-circuit the computers, and were responsible for the term debugging.

Another critical discovery, the sodium iodide crystal, was developed by Hofstadter in 1948. This enabled gamma ray counting and earned Hofstadter the Nobel Prize for Physics in 1961.
