A sample analyzer is configured to obtain first and second stage position data. The first stage position data indicates a first position of a movable stage in a first dimension, and the second stage position data indicates a second position of the movable stage in a second (perpendicular) dimension. The sample analyzer is configured to, based on the first and second stage position data, determine a viewing position of one or more viewing or imaging optics relative to the movable stage. The sample analyzer is configured to display a vessel map, which comprises a visual representation of a sample vessel associated with the movable stage. The sample analyzer is configured to display a viewing position marker overlaid on the vessel map. The viewing position marker indicates the viewing position of the one or more viewing or imaging optics relative to the sample vessel as represented by the vessel map.

An ophthalmic surgical system comprises a surgical microscope that provides a field of view of a surgical site to a user. A microscope display device displays a graphical overlay and the field of view. The graphical overlay displays fields to adjust configurable settings that modify operation of a surgical instrument. A footswitch receives user input from the user to adjust the configurable settings by: detecting a first movement of a joystick by the user, the first movement representing movement of a cursor relative to the fields; and detecting a second movement of the joystick or a button by the user, the second movement representing a selection of a field. The computer: generates a control signal to adjust the configurable settings in the response to the user input; and outputs the control signal to the surgical instrument to adjust the configurable settings according to the user input.

The present application discloses a light sheet microscope for imaging biological materials. The microscope uses a plurality of light beams, focused to an overlapping line to excite a fluorescent material within the biological sample. The laser-induced fluorescence image is then analyzed and displayed.

A surgical retractor includes a plurality of cameras integrated therein. One such retractor includes a tubular retractor and an insert supporting said plurality of cameras can be disposed within a tubular retractor.

An information processing device includes: a storage configured to store display region information and a count value, the display region information indicating a position of a predetermined display region in a first image corresponding to image data, the count value indicating frequency of display of each predetermined region in the first image; and a processor including hardware. The processor is configured to, based on the image data and an instruction signal for selecting the display region, generate a display image corresponding to the display region that is selected by the instruction signal, determine whether the display region information meets a first condition, add a predetermined value to the count value of the region on which it is determined that the first condition is met, and set, for a region of interest, a region that draws an interest in the first image based on the count value.

An auxiliary appliance for a user interface device having a touch sensitive screen includes at least one haptic control element configured to be manually operated by a user. An attachment portion is configured to be attached to the user interface device such that the haptic control element is superimposed on the touch sensitive screen of the user interface device in a predetermined screen area where a touch control element is provided on the touch sensitive screen. The touch control element is operable by touching the touch sensitive screen in the predetermined screen area. The haptic control element comprises a touch portion configured to touch the touch sensitive screen in the predetermined screen area to operate the touch control element in response to a manual user operation of the haptic control element in a state in which the attachment portion is attached to the user interface device.

An ergonomic digital imaging system obviates the need for, and replaces, the standard microscope with binoculars for viewing images, thereby freeing the user from using his or her hands to manipulate images seen through the binoculars of the microscope, whereby the user can use his or her hands for other tasks, such as dental or other surgery, from a position away from the exhaled breath of the patient being treated. The images are maintained focused, no matter how close or far the viewer is to the viewing display screen. The system is collapsible and portable, so that specialists can take the system from office to office, a plug and play work environment. The extended maneuverability of the camera head results in simple and fast patient positioning, and the camera and display module adjust for any comfortable sit or stand ergonomics of the practitioner.

The invention relates to a visualization device (1), in particular a virtual reality (VR) headset or head mounted display (HMD) for transferring images of a microscopy device (100), comprising: a supporting device (2) for arranging the visualization device (1) on the head of a user, at least one mounting device (3) for mounting at least one optical display device (4) about a point of rotation on the supporting device (2), wherein there is at least one drive device (5) via which the at least one optical display device (4) on the at least one mounting device (3) is movable between an operating position (B) and a rest position (R), such that the at least one optical display device (4) can be fixed, in the operating position (B), in the field of view of the user and, in the rest position (R), outside of the field of view of the user, wherein the drive device (5) is attached in a region outside of the point of rotation of the mounting device (3) on the at least one display device (4).

The invention relates to an optical system (7) comprising a display unit (5) for displaying an image and comprising an eyepiece (6) for observing the image. The eyepiece (6) comprises a first lens group (LG1) and a second lens group (LG2). An intermediate pupil (ZP) is arranged between the first lens group (LG1) and the second lens group (LG2). The second lens group (LG2) is designed to image the image displayed by the display unit (5) into the intermediate pupil (ZP). The first lens group (LG1) is designed to image the image arranged in the intermediate pupil (ZP) into a spatial region (B). The intermediate pupil (ZP) and the spatial region (B) are conjugate to one another. A filter unit (E, FE) and/or a wavefront manipulator (E, WM) is/are arranged at the intermediate pupil (ZP).

A system and method for automated analysis of a filter obtained from an air quality monitoring apparatus used for sampling airborne respirable particles such as asbestos fibres, synthetic mineral fibres, pollen or mould particles is described. The system comprises capturing images at a plurality of sample locations. At least one magnified phase contrast image is obtained at each sample location. An automated quality assessment is then performed using a computer vision method to assess one or more quality criteria. Failure may lead to the sample location being ignored for subsequent analysis, or the whole filter slide may be rejected if the overall quality is poor. The quality assessment may performed be in two stages comprising an overall filter quality assessment performed on a series of low power/magnification images captured over the filter and a field of view or graticule level quality assessment performed on high power/magnification images captured at individual sample locations on the filter. Images which pass the quality assessment are then analysed using a computer vision method to identify and count the number of respirable particles.
