Abstract: Exemplary methods, apparatus, and systems are provided for automated detection and registration of medical images using fiducial markers and processing algorithms. By either clustering fiducial markers having a different number, size, shape, configuration, or material property or by using fiducial markers arranged in a ring shape, wherein their arrangement is asymmetric, and then applying a feature extraction to extract the fiducial marker objects, and registering the fiducial marker objects with a model of the fiducial frame, automatic registration can be achieved.

Abstract: A spectrally encoded endoscopic probe. The probe has a light guiding component, a light focusing component, and a grating component. The probe is configured such that a set of light beams of multiple wavelengths are diffracted by the grating component in different orders at substantially the same angle. The set of light beams includes at least 3 light beams. Each light beam among the set of light beams is associated with a different wavelength.

Abstract: An image processing device is provided to generate electronic document data representative of at least one physical document having at least one page. A unique document identifier value is determined to identify the at least one page, the unique document identifier being determined based on an end document identifier value associated with an electronic document project managed by a document management system. An annotated electronic document is generated by embedding data representing the unique document identifier within the at least one page of the electronic document data. An information file is generated and includes at least one characteristic associated with the annotated electronic document. The information file and annotated electronic document are communicated to the document management system for incorporation into an associated electronic document project stored therein.

Abstract: An apparatus includes an elongate member having proximal and distal portions; a rotatable drive cable disposed within the elongate member, the drive cable being connectable to a mechanism to which torque can be applied; and a control assembly mechanically coupled to the drive cable, and configured to disengage the mechanism from the drive cable when the applied torque exceeds a predetermined level, wherein disengagement of the mechanism from the drive cable causes rotation of the drive cable to stop or withdrawal of the drive cable.

Abstract: Some systems comprise a light source; a spectrometer; an optical scope that has a longitudinal axis and that includes a rotatable optical assembly, which is coupled to the light source and to the spectrometer; and an oscillating-drive device that is coupled to the optical scope. Also, the oscillating-drive device and the optical scope are configured such that the oscillating-drive device can oscillate the rotatable optical assembly of the optical scope through greater than 90° of rotation around the longitudinal axis of the optical scope. And some systems comprise an optical scope that includes a rotatable optical assembly and a spooling mechanism. The rotatable optical assembly includes one or more light-guiding components. Furthermore, the spooling mechanism is configured to wind or unwind the one or more light-guiding components when the rotatable optical assembly rotates.

Abstract: Two-dimensional image acquiring apparatuses, systems, methods and storage mediums are provided herein. An apparatus includes a Spectrally Encoded Endoscopy (“SEE”) probe including a diffractive element, the diffractive element operating to separate and diffract a transmitted light into separated light beams such that the diffracted light beams are superposed or substantially superposed on a target region; an image sensor that operates to acquire one or more intensities from a detected light; and an imaging optical system that operates to image light beams separated from the detected light, wherein the diffractive element, the imaging optical system, and the sensor are disposed for each of the light beams separated from the detected light to acquire spectral data of each of the light beams separated from the detected light. The diffractive element operates to rotate such that an image of the image sensor is changed, and a two-dimensional image is acquired.

Abstract: A forward-viewing spectrally encoded endoscope (SEE) probe includes a light guiding component, a light focusing component, and a grating component arranged along a longitudinal axis of a drive cable. The SEE probe is configured for guiding light from the light guiding component, through the light focusing component, and to the grating component, and then forwarding a spectrally dispersed light line from the grating component towards an image plane. One or more of the light guiding component, the light focusing component, and the grating component is arranged at an angle with respect to the longitudinal axis of the drive cable so that at least one wavelength of the spectrally dispersed light line goes to the direction of axis of the drive cable.
