Abstract: A fluid management system may include an inflow pump providing a fluid inflow to a medical device, at least one pressure sensor, and a controller configured to receive pressure signals from the at least one pressure sensor, the pressure signals corresponding to a system pressure within the fluid management system. The controller may be configured to detect which one of a plurality of medical devices is fluidly connected to the inflow pump based on the pressure signals from the at least one pressure sensor and an rpm of the inflow pump.

Abstract: An imaging system and methods are presented for determining a size of a viewed object through a monocular endoscope. The system includes an imaging device mounted on the endoscope, at least one light source disposed in a fixed position relative to the imaging device, and a processor configured to receive input from the imaging device and analyze at least one of shadow effect from the light source, structured lighting provided by the light source, multi-point illumination including the light source, time-of-flight involving light pulses from the light source, and lateral color aberrations from the light source to determine the size of the viewed object.

Abstract: Systems and methods related to combing multiple images are disclosed. An example method of combining multiple images obtained by an endoscope includes obtaining a first input image formed from a first plurality of pixels, wherein a first pixel of the plurality of pixels includes a first characteristic having a first value. The method also includes obtaining a second input image formed from a second plurality of pixels, wherein a second pixel of the second plurality of pixels includes a second characteristic having a second value. The method also includes subtracting the first value from the second value to generate a motion metric and generating a weighted metric map of the second input image using the motion metric.

Abstract: Methods and devices are provided for determining anatomical distance and/or position measurements during an endoscopic procedure. Markings are placed either physically or superimposed on a distal end of an elongate tool, such that the markings are viewable in an imaging field of view of the endoscope. Anatomic distances may be determined by measurements performed with the tool. The size and/or position of anatomical structures or unknown objects may also be determined using the marked tool.

Abstract: Presented herein are systems and methods for registering one or more images of one or more subjects based on the automated generation of artificial landmarks. An artificial landmark is a point within an image that is associated with a specific physical location of the imaged region. The artificial landmarks are generated in an automated and robust fashion along the bones of a subject's skeleton that are represented in the image (e.g. graphically). The automatically generated artificial landmarks are used to correct distortion in a single image or to correct distortion in and/or co-register multiple images of a series of images (e.g. recorded at different time points). The artificial landmark generation approach described herein thereby facilitates analysis of images used, for example, for monitoring the progression of diseases such as pulmonary diseases.

Abstract: Aspects of the present disclosure provide systems, methods, devices, and computer-readable media for interference filter correction based on angle of incidence. In some examples, a sample emits an emission spectrum that is filtered by an emission filter to provide a transmission spectrum. The emission spectrum illuminates the emission filter at multiple angles of incidence. The angles of incidence result in a spectral shifting of the transmission spectrum. Based on this spectral shifting, the intensity of the transmission spectrum is corrected. An image corresponding to the corrected intensity of the transmission spectrum may be generated.
