摘要:
According to a first aspect, the invention relates to a method to support clinical decision by characterizing images acquired in sequence through a video medical device. The method comprises defining at least one image quantitative criterion, storing sequential images in a buffer, for each image (10) in the buffer, automatically determining, using a first algorithm, at least one output based on said image quantitative criterion and attaching said output to a timeline (11).

A method to inspect a solid organ in a subject includes introducing a needle in a predetermined area of the solid organ, inserting an optical probe through a lumen of the needle, and imaging the predetermined area using the optical probe. An optical probe to inspect a solid organ in a subject, the optical probe being intended to be positioned in the solid organ through a needle, the optical probe includes an optical fiber bundle, a ferule to protect the distal tip of the optical fiber bundle, the ferule comprising a shank and a head, and a sheath wrapping the fiber bundle and the shank, wherein the head of the ferule has a length adapted for the optical probe to image the solid organ while keeping the sheath inside the needle.
摘要:
A method for processing images acquired in real time through a medical device, said images being loaded into a buffer, comprising the steps of : stopping the loading of the images into the buffer, processing loaded images using an incremental algorithm, displaying successively intermediate results of the processing, resuming the loading and stopping the processing based on an evaluation of said intermediate results.
摘要:
The invention concerns an optical head for equipping the distal end of a flexible optical fiber bundle (2), designed to be urged into contact with an analyzing surface and comprising optical means (3) for focusing an excitation signal into a so-called excitation focal point located at a specific depth beneath the analyzing surface and for sampling a signal backscattered by the excitation focal point which is carried back by said fiber bundle. The invention is characterized in that it comprises an optics-holder tube (4) wherein are inserted on one side the distal end portion (1) of the fiber bundle (2) and on the other optical means, the latter including a plate (21) placed in contact with the end (14) of the fiber bundle whereof the index is close to that of the fiber core and a focusing optical block (3), an output window (30) being further provided adapted to provide index adaptation so as to eliminate parasitic reflection occurring on the analyzing surface.

The invention concerns an equipment comprising an image guide (1) consisting of flexible optical fibers with: on the proximal end side: a source (2), angular scanning means (3), injection means (4) in one of the fibers, means for splitting (5) the illuminating beam and the backscattered signal, means for spatial filtering (6), means for detecting (7) said signal, electronic means (8) for controlling, analyzing and digital processing of the detected signal and display; and on the distal end side: an optical head (9) for focusing the illuminating beam exiting from the illuminated fiber. The invention is characterized in that the means (3) comprise a resonant line mirror (M1) and a galvanometric field mirror (M2) with a variable frequency and two afocal optical systems adapted to conjugate the two mirrors (M1, M2) firstly in the field mirror (M2) and the injection means (4) in the image guide in a second step.
