A configurable scanner (1), adapted for contactless measurement of the depth and perimeter of a wound on a target body part (9), has a scan head (4), and a processor (3) for controlling a scanning procedure and analyzing the results. The scan head is translated along a substantially semicircular path (7) having a configurable radial distance from an imaginary axis, such that the imaginary axis is approximately coincident with an axis of the target (9). The scan head (4) projects a contour line having a calibrated length onto the target surface, and the processor (3) stores an image of the projected contour line captured by an image capturing device (11). The processor (3) analyzes a series of captured images to determine the coordinates in three axes of the projected contour line, creates therefrom a 3D model of the region of interest, and determines a depth and perimeter of the wound from the 3D model.
