Abstract:

Multispectral imaging systems are provided including a first light source having a first wavelength configured to image a sample; a second light source, different from the first light source, having a second wavelength, different from the first wavelength, configured to image the sample; and at least a third light source, different from the first and second light sources, having a third wavelength, different from the first and second wavelengths, configured to image the sample. A camera is configured to receive information related to the first, second and at least third light sources from the sample. A processor is configured to combine the information related to the first, second and at least third light sources provided by the camera to image an anatomical structure of the sample, image physiology of blood flow and perfusion of the sample and/or synthesize the anatomical structure and the physiology of blood flow and perfusion of the sample in terms of a blood flow rate distribution. The imaging system is directed and focused on a field of view (FOV) in a region of interest of the sample using an endoscope.

Abstract:

Methods for combining anatomical data and physiological data on a single image are provided. The methods include obtaining an image, for example, a raw near-infrared (NIR) image or a visible image, of a sample. The image of the sample includes anatomical structure of the sample. A physiologic map of blood flow and perfusion of the sample is obtained. The anatomical structure of the image and the physiologic map of the sample are combined into a single image of the sample. The single image of the sample displays anatomy and physiology of the sample in the single image in real time. Related systems and computer program products are also provided.

International Classification:

A61B 5/00

Abstract:

Some embodiments of the present inventive concept provide a system that uses two wavelengths of differential transmittance through a sample to apply laser speckle or laser Doppler imaging. A first of the two wavelengths is within the visible range that has zero or very shallow penetration. This wavelength captures the anatomical structure of tissue/organ surface and serves as a position marker of the sample but not the subsurface movement of blood flow and perfusion. A second wavelength is in the near Infra-Red (NIR) range, which has much deeper penetration. This wavelength reveals the underlying blood flow physiology and correlates both to the motion of the sample and also the movement of blood flow and perfusion. Thus, true motion of blood flow and perfusion can be derived from the NIR imaging measurement without being affected by the motion artifact of the target.
