Introducing a new design using proven, patented materials to permit rapid visualization of gray scale resolution power at continuous depths from 1 to 12 cm. Model 047 is a single simple tool to assess resolution of masses varying in size, depth and contrast. It is usable on all diagnostic ultrasound machines thus allowing user evaluation of gray scale sensitivity with a wide range of transducer frequencies. This phantom is an ideal training tool for learning optimum system setup and evaluating system performance.

Masses may be viewed with either a circular or elliptical cross-section. The mass diameters were selected so the volume imaged would double as the diameter increased. The gray-scale levels were selected to achieve a doubling in signal intensity as you move from mass to mass.

Gray Scale Phantom Procedure: For each probe combination scan laterally to detect maximum frequency of visualization. Freeze image, measure depth from scan surface to top of target of last visualization.

  • This phantom has a speed of sound, attenuation and backscatter coefficient that meets the suggested phantom properties of the AIUM Standard for Quality Assurance.
  • The anechoic masses comply with the ACR accreditation program.

The ACR recommends a variety of tests. This phantom is a very specific tool to assessing some performance measures but it would not be a suitable test object to meet all of the most common recommended testing requirements. If you need a more general purpose QA tool, please look at item 040 or 054; both of these fully comply with all requirements and recommendation of the AIUM and ACR.
