How Echocardiography is Used


25 July, 2011 | Cardiac Ultrasound

Echocardiography, also known as cardiac ultrasound, is an ultrasound- based diagnostic imaging technique used for visualizing of subcutaneous body structures, including: tendons, muscles, joints, vessel and internal organs, for possible pathology or lesions. In physics, “ultrasound” applies to all sound waves with a frequency above the audible range of human hearing, about 20,000 Hz. The [...]

Positron Emission Tomography (PET) Explained


19 July, 2011 | PET-CT

What is Positron Emission Tomography (PET)? Positron Emission Tomography (PET) is a relatively new medical imaging technique. PET is the most sophisticated nuclear medicine technique that produces 3D images or pictures of functional processes in the human organism. The Positron Emission Tomography (PET) system is designed to selectively detect pairs of gamma photons emitted, as [...]

Computed Radiography (CR) in Radiology Applications


11 July, 2011 | Computed Radiography

What is Computed radiography (CR)? Computed radiography (CR) is a cost-effective solution to move from analog to digital imaging. With computed radiography (CR) the transition to digital is completed by installing computed radiography (CR) readers and replacing X-ray cassettes (which use X-ray film) with computed radiography (CR) cassettes (which use imaging plates). The imaging plates [...]
