The different biomedical diagnostic instruments employed in medical measurements. We cover various biomedical diagnostic techniques employed that include and not limited to: X-rays, Magnetic resonance imaging (MRI), Ultrasound scanning, PET scanning, etc.
The application of ultrasonic in medical field is based on sonar principle as used by bats, anglers with fish detectors, and ships at sea. This is a totally non-invasive procedure. Acoustic waves are easily transmitted in water and are … Read More
PET scan is an imaging technique which produces images of the body by detecting radiation or gamma rays emitted from the body after the patient is injected with radioactive substance. When a positron emitted by a radioactive substance bombards an … Read More
MRI is based on the magnetic properties of hydrogen which is one of the constituents of cerebral tissue and other tissues. The hydrogen atom has a single proton which possesses a magnetic moment or behaves like a small magnet called … Read More
X-rays were discovered accidentally by the Germany Physicist William Roentgen in 1895, while experimenting with electron beams in a gas discharge tube. He discovered that a screen in the laboratory started glowing when the electron tube … Read More
Diagnostic techniques are investigations and tests performed on patients with the intention to identify the cause of illness. The ultrasound is sonic energy at frequencies above the audible range. The most widely used applications of ultrasound in diagnostic medicine involve … Read More
