Abstract
A method () at an imaging acquisition system (), comprising: obtaining a sequence of reflectance images (-); acquiring a sequence of fluorescence channel images (-) including light images (), acquired while using a light source to cause a target body-part to emit fluorescent light, alternating with dark images (), acquired without using the light source; determining () a first reflectance image () associated with a first fluorescence channel image () having a first reference time, and a second reflectance image () associated with a consecutive second fluorescence channel image () having a second reference time; determining () a transformation matrix based on a relative alignment of the first and second reflectance images; applying () the transformation matrix to one of the first and second fluorescence channel images to align these images; performing a subtraction () between the fluorescence channel image to which the transformation matrix has been applied and the other image to obtain a background-subtracted image; and outputting the background-subtracted image for displaying.
