Volume analysis and display of information in optical coherence tomography angiography

A system for computer aided visualization and diagnosis comprising:

• an imaging system under the control of at least one processor for acquiring an OCT dataset from a volume of anatomical tissue;
• and
• software stored on a computer-readable medium accessible to the at least one processor, containing instructions to cause the at least one processor to:
• evaluate the dataset for flow information using amplitude or phase information;
• generate a matrix of voxel values, representing flow occurring in vessels in the volume of tissue;
• perform volume rendering of these values by deriving three dimensional position and vector information of the vessels;
• and
• display the volume rendering information on a computer monitor, including generating depictions of the vessels;
• and
• use morphologic and reflectivity data in the assessment, including connectivity of voxels and feature characteristics, to classify the vessels.

A non-transitory computer readable medium containing recorded instructions to cause a processor to:

• acquire from an imaging system an OCT dataset from a volume of anatomical tissue;

• generate a matrix of voxel values, representing flow occurring in vessels in the volume of tissue;
• perform volume rendering of these values by deriving three dimensional position and vector information of the vessels;
• and
• display the volume rendering information on a computer monitor, including generating depictions of the vessels;
• and
• use morphologic and reflectivity data in the assessment, including connectivity of voxels and feature characteristics, to classify the vessels.
