Medical Imaging Ultrasound
This is a SOURCES SOUGHT NOTICE for market research purposes.
THIS IS NOT A REQUEST FOR PROPOSALS. INFORMATION RECEIVED
WILL BE USED FOR MARKET RESEARCH PURPOSES ONLY.
After the results of this market research are obtained and analyzed, NIST may conduct a competitive procurement and subsequently award a contract.
The Security Technologies Group (STG, 643.10) in the Materials Measurement Laboratory at NIST in Gaithersburg MD develops metrologies for energy absorption in soft polymers, elastomers, and tissue phantoms subjected to medium rate impacts. These materials may be opaque, clear, homogeneous, or have an internal structure (dispersed particles, vascular network, stiffness inhomogeneity). There is a need to measure velocity, displacements, and mechanical properties (modulus, viscosity, stiffness) inside the volume of soft materials (1 kPa - 1 MPa) during impact. Impact velocities range from 2 m/s to 8 m/s. The information from these measurements is utilized to develop constitutive equations and models of the material dynamic response. There is also a need to measure the structure and mechanical properties of the materials before and immediately after impact testing. The STG is seeking a medical imaging ultrasound with the capability to conduct supersonic shear wave elastography measurements at kHz imaging rates. The research and development nature of the application will require specific access to the instrument parameters and data.
Interested business organizations that believe they may be capable of meeting NIST's requirements detailed below should respond to this notice with a narrative clearly demonstrating their ability to meet NIST's requirement.
