Original Abstract Submitted
Methods and apparatus for quantifying an injected volume in an area of tissue during a medical procedure. In one example, a method includes determining a pixel-to-size scale parameter based on a pixelated image of a reference object included in a FOV of an optical instrument configured to perform volumetric imaging, the FOV further including an injection site; computing a first 3D model of the injected volume in the area of tissue based on a volumetric image of the FOV obtained using the optical instrument; refining the first 3D model to obtain a second 3D model of the injected volume, the refining including correcting a shape and a size of the first 3D model to reduce distortions associated with light refraction at a boundary of the injected volume in the area of tissue; and calculating a value of the injected volume based on the second 3D model and further based on the pixel-to-size scale parameter.
