Patent granted for processing electronic images from a medical device
A recently granted patent (Publication Number: US11776122B2) describes a system for processing electronic images from a medical device. The system includes a processor that performs various operations to process the images. These operations involve receiving an image frame from the medical device, identifying the location of an electromagnetic beam halo, determining the edges of the electromagnetic beam based on the halo, and determining size metrics of the beam based on its edges.
The system also generates a visual indicator for display on the image frame, which is based on the size metrics of the electromagnetic beam. Additionally, the system can extract features from the image frame within a predetermined distance of the beam and/or beam halo. The size of the visual indicator is determined based on these extracted features, and a weighting of each feature can be applied to determine the size of the indicator.
The visual indicator on the image frame corresponds to the size of an exit channel through which objects are passed. To determine the edges of the electromagnetic beam, the system defines a bounding box around the beam halo. It then distinguishes the approximated beam from image artifacts based on size and applies an algorithm to determine the edges.
In terms of determining the size metrics of the electromagnetic beam, the system fits a plurality of circle or ellipse candidates over the determined edges and determines the best-fitting candidate. The electromagnetic beam in this system is specifically described as a laser, and the size metrics correspond to the diameter or radius of the beam.
The patent also describes a method for processing electronic images from a medical device, which includes the same operations as the system. The method involves receiving an image frame, identifying the beam halo, determining the edges of the beam, and determining the size metrics of the beam. It also generates a visual indicator based on the size metrics and can extract features to determine the size of the indicator.
Lastly, the patent includes a non-transitory computer-readable medium that stores instructions for a computer to perform the operations described above. These operations involve receiving an image frame, identifying the location of an electromagnetic beam on the surface of the frame, analyzing the beam to determine size metrics of the surface, and generating a visual indicator based on the size metrics. The analysis of the beam involves determining its edges based on the beam halo and determining the size metrics based on these edges.
