Photon migration tomography facts
WebVisually opaque media are ubiquitous in nature.While some materials are opaque because they strongly absorb visible light, others, such as loam, white paint, biological tissue and milk, are opaque because photons traveling within them are predominantly scattered rather than absorbed. A vanishingly small number of photons travel straight through such … WebOptical Tomography in Resuscitation Management/Diagnosis DESCRIPTION (provided by applicant): This Phase I study explores the feasibility by which the technique of dynamic …
