An otoscope provides a circular display allowing a compact housing providing improved simultaneous viewing of the display and the patient's ear for improved positioning and stabilization of the otoscope. A recorded image may be rotationally corrected, and non-image data displayed on the screen may be rotationally corrected with the use of an inclinometer.

A method and apparatus for positioning a camera to capture images inside a body cavity of a patient during a medical procedure is disclosed. The apparatus includes an insertion tube, a plurality of connected linkages extending from a distal end of the insertion tube, each linkage having a threaded actuator received on a threaded end of a drive shaft extending between the threaded actuator and a proximal end of the insertion tube. The apparatus also includes a camera disposed at a distal end of the plurality of connected linkages. Each connected linkage has at least one associated movement actuated by movement of the threaded actuator in response to rotation of the drive shaft, the associated movements of the connected linkages together operable to facilitate positioning of the camera within the body cavity of the patient.

A method for supporting a user, a corresponding computer program product, a corresponding data medium, and a corresponding imaging system are provided. According to the method, a three-dimensional (3D) data set depicting a target object is provided, and at least one two-dimensional (2D) image of the target object is automatically acquired. The 2D image and the 3D data set are automatically registered with each other by a 2D/3D registration. A spatial direction in which the 2D/3D registration exhibits greatest uncertainty is automatically specified. A signal for aligning an instrument that is provided for the purpose of examining the target object is then automatically generated and output as a function of the specified spatial direction in order to support the user.

Devices, systems, and methods for catheterization through angionavigation, cardionavigation, or brain navigation to diagnose or treat diseased areas through direct imaging using tracking, such as radiofrequency, infrared, or ultrasound tracking, of the catheter through the patient's vascular anatomy. A steerable catheter with six degrees of freedom having at least a camera and fiber optic bundle, and one or more active or passive electromagnetic tracking sensors located on the catheter is guided through the vascular system under direct imaging. The direct imaging can be assisted with at least one of MRA imaging, CT angiography imaging, or 3DRA imaging as the roadmap acquired prior to or during 3D stereoangiovision. The system comprises RF transceivers to provide positioning information from the sensors, a processor executing navigation software to fuse the tracking information from the tracking sensors with the imaging roadmap, and a display to display the location of the catheter on the roadmap.

A medical imaging system is described that comprises an heating element configured to apply at least one heating pattern element to a material to locally heat the material; a sensor configured to capture the position of the heated material a predetermined time after the application of the heating pattern element; and circuitry configured to determine the change of the heating pattern applied to the material based upon the captured position of the heated material after the predetermined time.

Methods, endoscopic systems, and non-transitory, machine-readable storage media for adjusting an exposure of an endoscopic system are described. In an embodiment, the methods include emitting light with a light source into a proximal end of an endoscope light pipe; generating received light signals with a photodetector based on light received through the endoscope light pipe by the photodetector; displaying, with a display module, images based on the received light signals having a current image brightness; monitoring the received light signals for changes to the current image brightness; and adjusting a light source illuminance level, and in some embodiments a photodetector gain and exposure time, based on the current image brightness to maintain a target image brightness of the display module. In an embodiment, a brightness adjustment step size is less than a just-noticeable difference in brightness of an eye and is directly proportional to the current image brightness.
