Systems and methods for enhancing quality of a flow image of a sample of a subject are provided. The method comprises acquiring a first flow image from a plurality of first OMAG scans of the sample, and acquiring a structure image from a second OMAG scan of the sample. Data based on pixel intensity values from the flow image and pixel intensity values from the structure image are then plotted onto a graph and from the graph, may be differentiated into a first data group representing static structure signals and a second data group representing flow signals. The method then includes suppressing pixels in the flow image corresponding to the first data group. The flow signal may also be multiplied by a weighting factor to suppress artifacts in the image.

Methods and systems for enhancing microangiography image quality

Systems and methods of producing medical images of a subject are disclosed herein. In one embodiment, structural data and vascular data are acquired from a region of interest in the subject. A filter is generated using structural image data acquired from a second layer and blood flow image data received from a first layer in the region of interest. The filter is applied to vascular image data acquired from a second, deeper layer in the region of interest to form an image of the second layer having reduced tailing artifacts relative to the unfiltered vascular image data.
