Patent attributes
Systems, devices, and methods for identifying different structure types with distinct composition in vivo and adjusting surgical laser output accordingly in a medical procedure are disclosed. An exemplary laser treatment system comprises a laser system configured to generate a laser beam for delivery to a target in a body, and a controller circuit configured to receive a signal reflected from the target in response to electromagnetic radiation produced by a light source, and generate one or more spectroscopic properties from the reflected signal. The controller circuit can identify the target as one of a plurality of structure types, such as tissue types or calculi types with respective compositions, using the one or more spectroscopic properties. The laser system can be controlled to operate in an operating mode based on the target identification.
