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.
Claims19
A system, comprising:
- radiation source configured to emit an imaging radiation and a treatment radiation;
- and
- a handpiece operatively coupled to the radiation source, the handpiece defining an optical axis and configured to irradiate tissue during a treatment process with the imaging radiation and treatment radiation delivered along the optical axis, the handpiece being configured to contact and slide along the tissue during the treatment process while contact is maintained therebetween, the handpiece comprising:
- a window intersecting the optical axis, the window being configured to contact the tissue,
- a focus optic configured to focus the imaging radiation and/or the treatment radiation,
- a detector configured to detect a reflection of the imaging radiation reflecting off of a first focal region incident at a surface of the window, the surface being in contact with the tissue to generate an image of the tissue,
- wherein the focus optic is configured to image the view of the tissue using one of either microscopic imaging or wide field of view imaging and is configured to focus the treatment radiation to a second focal region displaced from the first focal region;
- and
- wherein the treatment radiation is a pulsed treatment radiation having a pulse duration of at least 1 picosecond.
A method, comprising:
- irradiating, using a radiation source, a first focal region of a first tissue section of a tissue with an imaging radiation, the first focal region being incident upon a surface of a window, the surface being in contact with the tissue;
- imaging, using a focus optic, an image of a view of the first tissue section, the image being generated based on the imaging radiation reflecting off of the surface at the first focal region;
- detecting, using a detector, the image;
- designating a target treatment region of the first tissue section based in part on the image;
- targeting a second focal region within the target treatment region, the second focal region being displaced from the first focal region;
- irradiating the second focal region with a pulsed treatment radiation;
- and
- moving the window to a second tissue section of the tissue displaced from the first tissue section while maintaining contact between the surface of the window and the tissue.
