Artificial Pacemakers

Cardiac pacemakers can help people to lead normal, active, and healthy lives. Pacemakers can also reduce the risk of sudden cardiac death by providing a shock to a fatal heart rhythm, saving the patient's life.

Types of Medical Imaging

Medical imaging is a rapidly expanding field. It started with X-rays, and the next modality, ultrasonography, took sixty years to appear. Since then, three-dimensional imaging of anatomical structures was made possible with CT and MRI scans. The most recent breakthroughs in medical imaging technology, such as fMRI, PET, and SPECT scanning, create...

Medical ultrasound imaging technology: How it works and how it is used

Ultrasound is one of the oldest forms of medical imaging, It can be used to uncover internal anatomy and to study blood flow throughout the body. Though best known for its use in pregnancy, it has many other applications and is an area of emerging technology.

The History of the DNA computer

The history of DNA computing is short, but full of amazing technological achievements. It has tantalizing potential for advances in computing speed and miniaturization. Medical applications may one day treat diseases and even cure cancer by installing computational genes directly into patients' DNA.

How DNA Computers work

The first DNA computer marked the beginning of a revolution in both computing and medical technology. This 1994 invention, developed at the University of Southern California, looked unremarkable -- a test tube of clear liquid. It showed that DNA not only can store information, but can process it. Here is how it worked.

An Overview of DNA Computing

DNA computing is a rapidly emerging technology that promises to outdo conventional computing in both speed and miniaturization. DNA computers will be cheaper to manufacture than desktop computers, but have the potential to be as powerful as supercomputers. Not only will they be useful for many of the same things traditional computers do, some DNA computers...
