Stone identification methods and systems

A method comprising:

• obtaining, with a camera, image data about one or more stone objects in a body cavity;
• generating from the image data, with a processor, a representation of the one or more stone objects in the body cavity;
• establishing, with the processor, a scale for the representation, wherein establishing the scale comprises:
• positioning an optical fiber adjacent the stone object, and
• comparing a marker on the optical fiber to the stone object to determine a reference measurement, wherein the marker includes one or more tick marks located on a distal portion of the optical fiber and positioned adjacent the stone object, and
• determining from the representation, with the processor, physical characteristics of the one or more stone objects, wherein determining the physical characteristics of the one or more stone objects includes determining the size of each of the one or more stone objects based on the scale;
• and
• analyzing, with the processor, the physical characteristics of the one or more stone objects to determine a removal status for each of the one or more stone objects.

A method comprising:

• receiving at a processor, from a camera, image data about one or more objects inside of a kidney;
• obtaining from the image data, with an image analyzer, a reference measurement of the stone object within a first image frame included within the image data;
• determining from the reference measurement, with the processor, a two-dimensional size of the stone object in the first image frame to determine a cross-sectional area of the stone object within the first image frame;
• generating from the image data, with the processor, a representation of the one or more objects in the kidney;
• determining, with the processor, from the representation, a size of each of the one or more objects by comparing a marker on a reference element to the object to determine a reference measurement and defining a scale based on the reference measurement;
• comparing, with the processor, the size of each of the one or more objects to a predetermined maximum size to determine a removal status for each of the one or more objects;
• moving the camera or the stone object to determine a depth of the stone object;
• and
• determining from the cross-sectional area and depth, with the processor, a volume of the stone object.
