VISUALIZATION OF HEART WALL TISSUE

摘要

Various aspects of the instant disclosure are directed to imaging tissue. As may be implemented in accordance with one or more embodiments, aspects of the present disclosure are directed to apparatuses and methods involving the following. A light source includes an array of light emitters that illuminate a tissue region of a heart wall with light at different wavelength ranges. A light collector collects multispectral images including respective images collected at each of the different wavelength ranges at which the tissue region is illuminated. A catheter positions the light source and light collector proximate the tissue region of the heart wall for respectively illuminating the tissue region and collecting the multispectral images. A display circuit collects and displays one or more images depicting a condition of the health of heart wall tissue, based on the respective images collected at the different ones of the wavelength ranges.

主权项

1. An apparatus comprising:
a light source including an array of light emitters configured and arranged to illuminate a tissue region of a heart wall with light at a plurality of different wavelength ranges; a light collector configured and arranged to collect a plurality of multispectral images including respective images collected at each of the different wavelength ranges at which the tissue region is illuminated by the light source; a catheter configured and arranged with the light source and the light collector to position the light source and light collector proximate the tissue region of the heart wall for respectively illuminating the tissue region and collecting the multispectral images; and a display circuit configured and arranged to collect and display at least one image depicting a condition of the health of the heart wall tissue region, based on the respective images collected at the different ones of the wavelength ranges.
