Abstract
Improved medical scope devices and systems are provided to with two imaging modes and user interface features based on the imaging modes. A medical scope has a shaft with a light emitter at the distal tip providing illumination light and an optical assembly including a wide-angle lens element. A processor controls a display to show an adjustable region of interest (ROI) smaller than a field of view of the image sensor. Responsive to designated conditions, a frame is selected for diagnostic image processing to determine whether a feature of interest (FOI) is present in the frame. Responsive to an FOI being present in the frame but outside the ROI, a notification is created on the electronic display.
Claims28
An imaging scope system, comprising:
- a shaft including a distal tip with a light emitter providing illumination light and an optical assembly including a wide-angle lens element;
- an image sensor assembly including an image sensor configured to receive at least a portion of light focused through the optical assembly and produce output signals;
- image forming circuitry adapted to receive the output signals and produce an image signal communicating a series of image frames;
- a processor coupled to the image forming circuitry and configured to perform one or more of:
- cause the light emitter to alter the illumination light from a first state to a second state, wherein the second state comprises illumination light appropriate to stimulate fluorescence;
- condition the image signal for presentation on an electronic display, the presentation including an adjustable region of interest (ROI) smaller than a field of view of the image sensor and omitting image data outside the ROI;
- and
- responsive to designated conditions, select a frame from the series for diagnostic image processing, and evaluate results of the diagnostic image processing to determine whether a feature of interest (FOI) is present in the frame.
A method comprising:
- at a processor, receive an image signal based on sensor data received from an image sensor of an imaging scope;
- and
- one or more of:
- cause a light emitter to alter illumination light from a first state to a second state, wherein the second state comprises illumination light appropriate to stimulate fluorescence;
- condition the image signal for presentation on an electronic display, the presentation including an adjustable region of interest (ROI) smaller than a field of view of the image sensor and omitting image data outside the ROI;
- responsive to designated conditions, select a frame from the series for diagnostic image processing, and
- perform diagnostic image processing and evaluating results of the diagnostic image processing to determine whether a feature of interest (FOI) is present in the frame.
The method according to 18, wherein the second state consists substantially of light from the spectral band spanning 350-450 nm.
