The Model 11-101 Pro-US MTF (Modulation Transfer Function) Ultrasound Phantom is a tissue-mimicking phantom for use as a routine technical quality assurance test device for resolution measurement. It provides a consistently comparable and reproducible result from a single image.
The phantom is a block of polyvinyl alcohol (PVA) containing test objects for radial MTF and geometry assessment, all wrapped in a polyvinyl chloride (PVC) cover. The PVA based material mimics the sound velocity and acoustic attenuation of human tissue and is nontoxic, durable, and easy to handle and maintain.
Phantom images can be sent via DICOM (Digital Imaging and Communications in Medicine) format to an existing display to calculate and process the MTF of the image file. Optional Pro-US MTF software is available to auto-analyze the MTF of the image file.
