Abstract
Methods, apparatus, and systems for detecting hemozoin and diagnosing malaria infection are disclosed.
Claims20
A method for identifying hemozoin within retinal blood vessels, comprising:
- providing electromagnetic energy through a pupil to one or more retinal ocular blood vessels, the electromagnetic energy configured to induce Raman scattering of hemozoin present within the one or more retinal ocular blood vessels;
- determining locations of the one or more retinal ocular blood vessels by selectively detecting one or more characteristics of an electromagnetic response associated with provided electromagnetic energy through the pupil to one or more retinal ocular blood vessels;
- detecting a Raman spectral response for hemozoin present within the one or more retinal ocular blood vessels;
- and
- generating a response indicative of a malarial infection based on the Raman spectral response.
