  • Patent number: 10024785
    Abstract: Novel biophotonic phantoms are provided herein that can accurately mimic the optical properties of living tissue. The disclosed biophotonic phantoms comprise hemoglobin (Hb) in a native conformation that is distributed in a solid polymer matrix. Methods of producing the disclosed biophotonic phantoms are also provided. The biophotonic phantoms can be used, for example, to calibrate or test an optical imaging system, such as a near infrared spectroscopy imaging system.
    Type: Grant
    Filed: June 20, 2016
    Date of Patent: July 17, 2018
    Assignees: The United States of America, as represented by the Secretary, Department of Health and Human Services, University of Maryland, College Park
    Inventors: Hyounguk Jang, Jianting Wang, Yu Chen, Thomas Joshua Pfefer
  • Patent number: 9920188
    Abstract: Novel phantoms are provided herein that can accurately mimic the optical and/or acoustic properties of living tissue. The disclosed phantoms are constructed of one or more polyvinyl chloride plastisol (PVCP) gels comprising a PVC and a binary plasticizer. The phantoms can be used, for example, to calibrate or test an optical and/or acoustic detection system, such as a photoacoustic imaging system or an ultrasound imaging system.
