Medical imaging, diagnosis, and therapy using a scanning single optical fiber system

An integrated endoscopic image acquisition and therapeutic delivery system for use in minimally invasive medical procedures (MIMPs). The system uses directed and scanned optical illumination provided by a scanning optical fiber or light waveguide that is driven by a piezoelectric or other electromechanical actuator included at a distal end of an integrated imaging and diagnostic / therapeutic instrument. The directed illumination provides high resolution imaging, at a wide field of view (FOV), and in full color that matches or excels the images produced by conventional flexible endoscopes. When using scanned optical illumination, the size and number of the photon detectors do not limit the resolution and number of pixels of the resulting image. Additional features include enhancement of topographical features, stereoscopic viewing, and accurate measurement of feature sizes of a region of interest in a patient's body that facilitate providing diagnosis, monitoring, and / or therapy with the instrument.

Method and apparatus for continuous guidance of endoscopy

Methods and apparatus provide continuous guidance of endoscopy during a live procedure. A data-set based on 3D image data is pre-computed including reference information representative of a predefined route through a body organ to a final destination. A plurality of live real endoscopic (RE) images are displayed as an operator maneuvers an endoscope within the body organ. A registration and tracking algorithm registers the data-set to one or more of the RE images and continuously maintains the registration as the endoscope is locally maneuvered. Additional information related to the final destination is then presented enabling the endoscope operator to decide on a final maneuver for the procedure. The reference information may include 3D organ surfaces, 3D routes through an organ system, or 3D regions of interest (ROIs), as well as a virtual endoscopic (VE) image generated from the precomputed data-set. The preferred method includes the step of superimposing one or both of the 3D routes and ROIs on one or both of the RE and VE images. The 3D organ surfaces and routes may correspond to the surfaces and paths of a tracheobronchial airway tree extracted, for example, from 3D MDCT images of the chest.

Ultrasound endoscope

An ultrasound endoscope having an endoscopic observation system along with an ultrasound scan system. An outlet opening of an instrument passage, which is shunted from a biopsy channel of the endoscope, is located within a view field of an endoscopic image pickup window, which largely overlaps a scan range of the ultrasound scan system. A puncture instrument having a sharp-pointed rigid needle at the instrument outlet opening, which is in the view field of the endoscopic image pickup, can be monitored by way of the endoscopic observation system to check its position for safety purposes, from a slightly projected position to a largely projected position whenever it spontaneously gets out of the instrument outlet opening. Once the puncture needle is driven into an intracavitary wall toward a diseased portion in target, it can be monitored through the ultrasound scan system.

Virtual endoscopy

InactiveUS20080118117A1Full effectImproved angular separationSurgeryEndoscopesData setVirtual camera
A method of orienting a virtual camera for rendering a virtual endoscopy image of a lumen in a biological structure represented by a medical image data set, e.g., a colon. The method comprises selecting a location from which to render an image, determining an initial orientation for the virtual camera relative to the data set for the selected location based on the geometry of the lumen, determining an offset angle between the initial orientation and a bias direction; and orienting the virtual camera in accordance with a rotation from the initial orientation towards the bias direction by a fractional amount of the offset angle which varies according to the initial orientation. The fractional amount may vary according to the offset angle and / or a separation between a predetermined direction in the data set and a view direction of the virtual camera for the initial orientation. Thus the camera orientation can be configured to tend towards a preferred direction in the data set, while maintaining a good view of the lumen and avoiding barrel rolling effects.

Electronic endoscope system with color-balance alteration process

An electronic endoscope system includes a video scope having a solid-state image sensor for successively producing a frame of color image-pixel signals, and an image-signal processor for producing a color video signal based on the frame of color image-pixel signals. A calculation system calculates a difference value between a value of a central single-color image-pixel signal and an average of values of one selected from single-color image-pixel signals surrounding the central single-color image-pixel signal. A color-balance alteration system alters the value of the central single-color image-pixel signal based on the difference value calculated by the calculation system. A selection system performs the selection of the circumferential image-pixel signals such that the circumferential image-pixel signals to be selected are farther from the central image-pixel signal, as a spatial frequency of an endoscope image to be reproduced based on the color video signals is lower.
