Abstract:
FIG. 3A: 140 Canal à endoscope 200 Endoscope de petite taille 130 Canal pour le robot 180 Canal d'aspiration 104 Extrémité distale 100 Endoscope de grande taille A master - slave robotic endoscopy system includes a flexible primary endoscope probe having at least one tool channel for carrying a tendon-sheath driven robot arm and corresponding end effector, and a secondary endoscope probe channel for carrying an imaging endoscope. The imaging endoscope provides enhanced image capture range relative to a distal end of the primary endoscope probe by way of a secondary endoscope probe channel distal opening proximally offset from the primary endoscope probe distal end; a ramp structure disially carried by the primary endoscope probe; and/or one or more actuatable distal imaging endoscope regions. Robot arms can include joint primitives that enable robot arm / end effector manipulation in accordance with intended degrees of freedom. A set of quick connect / disconnect interfaces couple an actuation controller to one or more actuation assemblies insertable into the tool channel(s), where each actuation assembly includes tendon-sheath elements, a robot arm, and its corresponding end effector.
Abstract:

Abstract:
A method of achieving instrument independent measurements for quantitative analysis of fiber-optic Raman spectroscope system, the system comprising a laser source, a spectroscope and a fiber optic probe to transmit light from the laser source to a target and return scattered light to the spectroscope, the method comprising transmitting light from the laser source to a standard target having a known spectrum, recording a calibration spectrum of the scattered light from the standard target, comparing the known spectrum and the calibration system and generating a probe and/or probe-system transfer function, and storing the transfer function. Further provided is a method of performing real-time diagnostic Raman spectroscopy optionally in combination with the other disclosed methods.
Abstract:
A method of calibrating a fibre-optic Raman spectroscope system 20 comprising a laser source 21, a spectroscope 30 and a fibre-optic probe 11 to transmit light from the laser source to a target and return scattered light to the spectroscope, comprises transmitting light from the laser source to a standard target having a known spectrum, recording a calibration spectrum of the scattered light from the standard target, comparing the known spectrum and the calibration spectrum and generating a transfer function, and storing the transfer function. The transfer function is then used on further spectral measurements using the spectroscope system. A method of estimating laser power in the system and a method of subtracting a background signal from a Raman spectrum is also disclosed.
