Unmet Need
· Medical imaging phantoms are “stand-ins” for human tissue, used to benchmark and ensure quality control and subsequent calibration of imaging systems; however, as modern medical imaging methods become more sophisticated, patient-specific anatomy and clinical scenarios have become increasingly critical for this quality assurance. Current efforts for anthropomorphic phantoms are primarily designed for 3D imaging, but are either unideal for calibration of projection and dynamic imaging, or impractical to fabricate at adult-sized scales. Therefore, there is a need for clinically relevant radiographical phantoms capable of dynamic imaging and representation of adult tissue sizing.
Value Proposition
· Accurate line integral reproduction for benchmarking
· Printing and material modalities allow for thicknesses of adult, human torso
· Modular, 3D printed layer allows for easy reproductions of anatomical variation
· Improved incorporation of dynamic imaging tasks (like contrast agent injection)
Technology Description
· Researchers at Johns Hopkins have developed a method to produce an adult human-sized medical imaging phantom with clinically relevant complexity and variation, with projection and dynamic imaging task capabilities. Using a combination of materials and 3D printing techniques, these phantoms are easily customized to patient-specific anatomy for improved calibration of imaging systems, and can easily incorporate other imaging tasks with additional layers in the phantom. Additionally, this phantom is uniquely at-scale for adult patients for these radiographical benchmarking tasks.
Stage of Development
· This technology is currently in the proof-of-concept stage.
