Imaging Phantom
Imaging Phantom (pronunciation: /ˈɪmɪdʒɪŋ ˈfæntəm/) 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. These devices include Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Ultrasound, X-ray, and Positron Emission Tomography (PET) among others.
Etymology
The term "Imaging Phantom" is derived from the Greek word 'Phantasma' which means 'image' or 'apparition'. In the context of medical imaging, it refers to an object that mimics the human body or its parts and is used as a standard to calibrate imaging devices.
Types of Imaging Phantoms
There are several types of imaging phantoms, each designed to serve a specific purpose or to mimic a particular tissue or organ. Some of the common types include:
- Anthropomorphic Phantoms: These are designed to mimic the human anatomy in a realistic manner. They are often used for training and simulation purposes.
- Dosimetry Phantoms: These are used to measure the dose distribution of radiation in the human body.
- Resolution Phantoms: These are used to measure the spatial resolution of an imaging system.
