Abstract
A system () is provided for imaging a patient's interior. The system comprises an imaging sensor () for acquiring a series of images of a region of interest () in the patient's interior, and a plurality of light sources () for illuminating the region of interest in the patient's interior from different light source directions (-). A light controller () is provided for controlling individual ones (-) of the plurality of light sources () to dynamically vary the light source directions (-) during said acquiring. Moreover, a processor () is provided for obtaining lighting data () indicative of the dynamically varying light source directions. The processor () is further arranged for using the lighting data to apply a photometric stereo technique to the image data so as to establish a three-dimensional [3D] surface profile of the region of interest. The processor () is further provided to detect insufficiently illuminated areas of the region of interest (-) in the images acquired by the imaging sensor (), using the 3D surface profile of the region of interest. Accordingly, the system is enabled to establish a 3D surface profile of the region of interest from a series of images in a convenient and cost-effective manner.
