What is phantom in ultrasound?

What is phantom in ultrasound?

Imaging phantom, or simply phantom, is a specially designed object that is scanned or imaged in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices.

How does ultrasound elastography work?

Elastography directs painless low frequency vibrations into the liver. Ultrasound (US) or magnetic resonance imaging (MRI) measures how quickly these vibrations move through the organ. A computer uses this information to create a visual map showing the stiffness (or elasticity) of the liver.

What does phantom mean?

1a : something apparent to sense but with no substantial existence : apparition. b : something elusive or visionary. c : an object of continual dread or abhorrence the phantom of disease and want.

Why is elastography used?

An elastography is used to diagnose fatty liver disease (FLD) and fibrosis. FLD is a condition in which fat builds up in the liver. This fat can lead to cell death and fibrosis.

Why is elastography important?

Elastography is used for detection and diagnosis of breast, thyroid, and prostate cancers. Certain types of elastography are also suitable for musculoskeletal imaging, and they can determine the mechanical properties and state of muscles and tendons.

How do you make medical gel?


  1. Combine 1 part corn starch to 10 parts water in a pan.
  2. Heat this mixture while stirring constantly at medium heat for 5-10 minutes.
  3. When the substance begins to boil, turn off the heat and allow the mixture to cool.
  4. Pour the mixture into a clean, preferably sterilized, container.
  5. Ultrasound away!

What are phantom membranes used for?

While a Minecraft phantom membrane doesn’t serve much of a purpose on its own, it can be added to potions or used to repair the rare Elytra wings. To repair your precious wings, combine your damaged Elytra with your phantom membrane using an anvil.

What does phantoms of the mind mean?

An image that appears only in the mind; an illusion. Phantoms of a disturbed mind. Believed to be real even though illusory.

Is elastography and ultrasound?

Ultrasound elastography, also known as Fibroscan, the brand name of the ultrasound device. The test uses sound waves to measure the stiffness of liver tissue. Stiffness is a sign of fibrosis. MRE (magnetic resonance elastography), a test that combines ultrasound technology with magnetic resonance imaging (MRI).

How is elastography performed?

Liver elastography involves the use of a surface ultrasound probe that delivers a low frequency pulse or shear wave to a small volume of liver tissue under the rib cage. The transmission of the sound wave is completely painless.
