Multispectral medical imaging devices and methods thereof

Abstract

A multispectral medical imaging device includes illumination devices arranged to illuminate target tissue. The illumination devices emit light of different near-infrared wavelength bands. The device further includes an objective lens, a near-infrared image sensor positioned to capture image frames reflected from the target tissue, and a visible-light image sensor positioned to capture image frames reflected from the target tissue. A processor is configured to modulate near-infrared light output of the plurality of illumination devices to illuminate the target tissue. The processor is further configured to determine reflectance intensities from the image frames captured by the near-infrared image sensor and to generate a dynamic tissue oxygen saturation map of the target tissue using the reflectance intensities. The device further includes an output device connected to the processor for displaying the dynamic tissue oxygen saturation map.

Description

technical field [0001] The present invention relates to medical imaging, and more specifically, to a multispectral medical imaging device and method thereof. Background technique [0002] Multispectral medical imaging is known for measuring blood vessel and tissue oxygenation. It is an important tool. Quantified oxygenation data can assist medical professionals in providing better patient care. [0003] State-of-the-art techniques for multispectral medical imaging suffer from various drawbacks. Some tools only provide the ability to perform spot measurements on small areas of tissue. Other tools are only able to provide still images or low frame rate moving images, which can make clinical assessment more difficult. Some tools lack convenient methods to accurately and repeatedly locate and target target areas on the patient. In addition, it is often the case that environmental conditions such as overhead lighting and patient details such as skin color adversely affect th...
