THz radiation has found two fundamental modes of application in medicine and biology: spectroscopy and imaging. In both in vivo and in vitro tests, THz radiation has been shown to perform well when compared to the standard in vitro histological testing. Other areas where THz is finding use is in dentistry, wound assessment and more.

The History of X-Ray X-rays are capable of penetrating some thickness of matter. Medical x-rays are produced by letting a stream of fast electrons come to a sudden stop at a metal plate. It is believed that X-rays emitted by the sun or stars also come from fast electrons. The images produced by X-rays are [...]
What is Digital Radiology (DR)? Digital radiology (DR) is a form of x-ray imaging, where digital x-ray sensors are used instead of traditional photographic film. Advantages of digital radiology (DR) include time efficiency, as a result of being able to do without the standard chemical processing, as well as the ability to digitally transfer and [...]
CT Scanner Gantry Basic Components The largest component of a CT scanner system is referred to as the scan or imaging system. The imaging system primarily includes the CT scanner gantry and patient table or couch. The CT scanner gantry is a moveable frame that contains the x-ray tube, including: collimators and filters, detectors, data [...]
Tomosynthesis is a method for producing images of slices through the body using a general radiographic X-ray system with a direct digital radiography detector. This is accomplished by obtaining a large number of image acquisitions across a range of projection angles of the X-ray tube. Currently, tomosynthesis is an optional add-on for suitable DR systems.

Cardiovascular X-ray equipment is used to produce dynamic images of the patient’s heart and blood vessels. Historically, these systems used an image intensifier, attached to a video camera, to display the images. Modern systems use flat panel detectors, which are substantially lighter than image intensifiers, allowing faster C-arm rotations, therefore reducing examination times. With current [...]
