Small Parts Gray Scale Phantom

  • Axial and lateral resolution targets at 1, 3.5 and 6 cm for precise resolution measurements
  • Low scatter cysts of 1, 2, 4 and 7 mm diameters to evaluate system noise and distortion7 mm gray scale targets of -6 dB, +6 dB and high scatter relative to background material
  • Attenuation coefficients of 0.5 or 0.7 dB/cm/MHz
  • Convertible water dam for gel or water coupled scanning
  • Integral cover to protect scanning surface
  • Durable ergonomic design for handling ease

The Precision Small Parts Gray Scale Phantom 404GS LE provides advanced technology for measuring image quality of small parts and intra-cavity ultrasound scanning systems. With added gray scale targets this small parts phantom also measures contrast, temporal resolution and system linearity. The 404 LE has the same general target layout and specifications as the 404GS LE but does not include gray scale targets.

This phantom incorporates our new Tissue Mimicking (TM) gel which provides a smoother background texture and a new composite film scanning surface that has improved transmission properties so more of the ultrasonic beam can be transmitted and received.

Unique to the Precision Small Parts Gray Scale Phantom are closely spaced pin targets ideal for testing a range of high frequency transducers. Resolution patterns and all vertical and horizontal targets are made of 0.1 mm nylon fibers for better detail definition and spatial resolution.

Three gray scale targets of -6 dB, +6 dB and high scatter relative to the background material are included in the 404GS LE.

Optional accessories for the Precision Small Parts Gray Scale Phantom include Soft Foam-Lined Carrying Case, Rigid Case, or the Precision Ultrasound Transducer Guide.
