摘要： In a case where a line drawing, such as a thin line, is included within input image data, the output of a non-ejectable nozzle is compensated for while suppressing deterioration of reproducibility thereof. Based on positional information for specifying an abnormal nozzle in which an ejection failure has occurred among a plurality of nozzles arrayed in a nozzle column, a pixel value of a pixel on a pixel line corresponding to the abnormal nozzle and a pixel value of a pixel on a pixel line corresponding to another nozzle that is located in close proximity to the abnormal nozzle and in which no ejection failure has occurred are exchanged for the input image data. Then, halftone image data is generated by performing halftone processing for the input image data for which pixel value exchange has been performed.

摘要： A tissue resecting device includes a housing having an outer shaft, the outer shaft including a tool portion disposed at a distal end thereof having a window defined therein with a proximal cutting edge. An inner shaft is disposed within the outer shaft and includes proximal and distal ends, the inner shaft configured to rotate upon actuation thereof. A cork-screw member extends distally from the distal end of the inner shaft and into the window. The cork-screw member is configured to rotate concomitantly with the inner shaft and includes a barb at a distal end thereof configured to pierce and retain tissue thereon. Upon rotation of the inner shaft, the barb pierces and retains tissue and withdraws tissue proximally along the cork-screw member and into the outer shaft and wherein excess tissue is excised by the proximal cutting edge of the window as the tissue is withdrawn through the outer shaft.

摘要： A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

摘要： Methods, systems, and devices for accessing tissue outside a bronchus and marking the location of a biopsy are provided. The method includes loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting an extended working channel (EWC) including a location sensor into a patient's airways, registering a sensed location of the EWC with the CT volume of the navigation plan, and selecting a target in the navigation plan located outside the periphery of a patient's airways. The method further includes navigating the EWC and location sensor proximate the target, inserting a piercing catheter into the EWC, piercing through an airway wall to reach the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.

摘要： A laser system for generating a narrow linewidth semiconductor light beam includes a substrate, a gain chip affixed on the substrate and configured to amplify light beam, and an optical feedback photonic chip affixed on the substrate, optically coupled to the gain chip, and configured to output light beam, which has a narrow linewidth around a resonant frequency of the optical feedback photonic chip, to the gain chip. The optical feedback photonic chip includes first and second optical gratings, a first multimode interferometer (MMI) and a second MMI optically coupled with a respective end of the first and second optical gratings, a third MMI configured to output two light beams to the first and second MMIs, respectively, through a respective waveguide. Based on receiving a respective one of the two light beams, the first MMI outputs two light beams to its respective end of the first and second optical gratings and the second MMI outputs two light beams to its respective end of the first and second optical gratings, the first and second optical gratings output second and third light beams, the second light beam, of which a linewidth is narrower than a linewidth of the third light beam, is directed to the third MMI, and an output port of the third MMI is configured to direct the second light beam to the gain chip.

摘要： A reduction in quality of a virtual viewpoint image is suppressed. An image processing apparatus specifies an image in which a specific position in a target object is not occluded by another object from among a plurality of images obtained by the plurality of imaging apparatuses based on a pixel value of the plurality of images; determines, based on the specified image, a value of a pixel corresponding to the specific position in the virtual viewpoint image to be generated based on the plurality of images; and generates the virtual viewpoint image including the target object based on the determined value of the pixel.

摘要： An object is to enable highly accurate density unevenness correction while suppressing a reduction in productivity of printing accompanying correction value calculation for density unevenness correction. In the image processing apparatus, density correction information that specifies an output tone value for implementing a target density for an input tone value for each nozzle and which does not include the influence by a non-ejectable nozzle that cannot eject ink normally is acquired. In a case where a non-ejectable nozzle is detected during printing processing, output tone values corresponding to the detected non-ejectable nozzle and peripheral nozzles thereof among output tone values specified in the density correction information are changed.

摘要： The present disclosure is directed to a robotic surgical system and a corresponding method. The system includes at least one robot arm and a radiation source coupled to the robot arm. The system also includes a surgical table having a digital imaging receiver configured to output an electrical signal based on radiation received from the radiation source. A controller having a processor and a memory is configured to receive the electrical signal and generate an initial image of a patient on the surgical table based on the electrical signal. The controller transforms the initial image to a transformed image based on an orientation of the radiation source.
