Embodiment Construction

[0055] exist figure 1 In , a global schematic diagram of the method according to the invention is shown.

[0056] The method can be divided into four parts: part 1 related to fiber detection, adjustment part 2, measurement part 3 and reconstruction part 4. Part 1 and Part 2 correspond to figure 2 block diagram in , while part 3 corresponds to image 3 block diagram of , and Figure 4 corresponds to Figure 4 block diagram.

[0057] exist figure 1 Among them, according to the present invention, when it is desired to acquire multiple images, an adjustment step is first performed. For this purpose, a reference image 5 is considered, which is subjected to a step of probing the fibers 6 so as to obtain an image 7 representative of the relevant composition of each fiber. Reference image 5 is an image acquired by a system comprising a waveguide comprising a plurality of optical fibers, eg comprising 10,000 to 30,000 optical fibers. A reference image 5 was acquired, allowing ...

Abstract

The invention relates to a method for processing images acquired through a waveguide comprising a plurality of optical fibers. The invention is characterized in that, for each fiber, it consists of isolating on the acquired image the region corresponding to said fiber, performing local processing on each fiber individually in order to correct the photon flux detected in each fiber. amount, and then reconstruct the acquired image by eliminating the pattern caused by the fiber. The method also includes a sampling process for obtaining, for each fiber and from the sampled image, a sample injection rate that can be used to reconstruct the acquired image. The invention also includes a prior step which involves passing the target detection fiber.

Description

technical field [0001] The invention relates to a method for processing images acquired through a waveguide comprising a plurality of optical fibers. Background technique [0002] It is very advantageous if the invention is applied in the field of medical imaging. However, the present invention has wider applicability because it can be applied to any field in which imaging is achieved by a waveguide including a plurality of optical fibers. The image waveguide makes it possible to obtain an image. Such a device allows laser scanning and precise movement of the light source and receiver away from the object to be viewed. For example, in a laser scanning system in which a confocal image is obtained, the image waveguide contains several thousand optical fibers, and the spatial structure of the image waveguide is the same at the light entrance and light exit. Viewing an object through the waveguide can be compared to viewing through a grid due to the loss of information betwee...
