Abstract
A system includes a focus optic configured to converge an electromagnetic radiation (EMR) beam to a focal region located along an optical axis. The system also includes a detector configured to detect a signal radiation emanating from a predetermined location along the optical axis. The system additionally includes a controller configured to adjust a parameter of the EMR beam based in part on the signal radiation detected by the detector. The system also includes a window located a predetermined depth away from the focal region, between the focal region and the focus optic along the optical axis, wherein the window is configured to make contact with a surface of a tissue.
Claims12
A method of treatment, comprising:
- imaging a target tissue with imaging radiation delivered along an optical pathway to create a signal radiation emanating from the target tissue, the signal radiation generated by plasma formed in the target tissue through interaction with the imaging radiation;
- scanning the imaging radiation along the optical axis to alter characteristics of the signal radiation;
- determining one or more aspects of the target tissue based on the altered signal radiation;
- receiving, from a controller in electrical communication with the optical pathway and based on the determined one or more aspects of the target tissue, one or more suggested changes to a set of baseline parameters of a treatment radiation;
- adjusting, based on the received one or more suggested changes, the set of baseline parameters to result in an adjusted treatment radiation;
- and
- emitting the adjusted treatment radiation delivered along the optical pathway to treat the target tissue.
A method of treatment, comprising:
- irradiating a target tissue with an imaging EMR beam delivered along an optical pathway to image the target tissue;
- detecting at least a portion of a signal radiation caused by the imaging EMR beam reflecting off of the target tissue and by plasma generated in the target tissue;
- scanning the imaging EMR beam along the optical pathway to adjust characteristics of the signal radiation;
- determining one or more aspects of the target tissue based on the adjusted characteristics of the signal radiation;
- receiving, from a controller and based on the determined one or more aspects of the target tissue, one or more recommended adjustments to parameters of a treatment EMR beam;
- adjusting the parameters of the treatment EMR beam based on the one or more recommended adjustments;
- and
- irradiating a target tissue with the adjusted treatment EMR beam delivered along the optical pathway to treat the target tissue.
