Systems and methods for controlling energy delivered to an area of tissue during a treatment procedure are provided. The system includes a device for delivering energy to the area of tissue; an energy generator for generating and supplying energy to the device; and a controller for controlling an amount of energy generated by the energy generator and delivered to the area of tissue by the device. Controlling the amount of energy delivered to the area of tissue alters a primary zone of the area of tissue to a first level, alters a secondary zone to a second level, alters a tertiary zone to a third level, or a combination thereof, where the first level, the second level, the third level, or a combination thereof is predetermined, and where a coverage area of the primary zone, the secondary zone, the tertiary zone, or a combination thereof is also predetermined.

A computer-implemented method of providing optimized values of treatment parameters of a thermal ablation device for treating a region of interest within a subject, is provided. The method includes: iteratively adjusting initial values of the treatment parameters based on a difference between the predicted effect of the treatment parameters on the region of interest predicted by a relatively less computationally-expensive model, and a desired effect of the treatment parameters on the region of interest, to provide the optimized values of the treatment parameters; intermittently inputting the adjusted values of the treatment parameters into a relatively more computationally-expensive model; and updating the relatively less computationally-expensive model, and/or a mapping between the values of the parameters inputted into the models, such that the predicted effects of both models on the region of interest more closely match one another.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

A system for surgical planning and assessment of spinal deformity correction is provided that has a spinal imaging system and a control unit.

The present invention is directed to a multi-probe ablation simulation and guidance system and method for use in tissue ablation procedures. In use, the relative locations of a plurality of ablation probes capable of providing ablation energy are determined, and the effect of energy provided by the probes based on the determined locations is predicted to identify a simulated ablation volume. This simulated ablation volume is compared with a target tissue volume. The relative locations of the probes can be adjusted based on the comparison between the simulated ablation volume and the target tissue volume, and the predicted effect rerun until the simulated ablation volume encompasses the target tissue volume to be ablated and necrotized.

A surgical system for applying an energy applicator to a target tissue and methods operating the same are disclosed. The energy applicator extends from a surgical instrument. The surgical system comprises a sensor to measure external forces and torques placed on the surgical instrument. A surgical manipulator is configured to move the energy applicator in a manual mode in response to the external forces and torques. At least one controller is configured to: model the surgical instrument and the energy applicator as a virtual rigid body having a virtual mass; calculate, using impulse modeling, constraining forces and torques to be applied to the virtual rigid body; determine total forces and torques based on the external forces and torques and the constraining forces and torques; and advance the energy applicator in the manual mode based on the total forces and torques.

According to a computer-implemented method for planning therapeutic ultrasound treatment of a three-dimensional tissue region, a tissue model containing a material parameter relating to deformability and/or elasticity of a corresponding material of the tissue region is provided in spatially resolved and/or directionally resolved form. Based on the tissue model, part of the tissue region is determined as a treatment region, and, depending on the tissue model and the treatment region, a therapeutic plan is generated to change the at least one material parameter. The therapeutic plan includes at least one characterization parameter that characterizes a plurality of lesions with respect to spatial arrangement and/or pose and/or shape and/or at least one configuration parameter of the plurality of lesions for a therapeutic ultrasound apparatus for generating the plurality of lesions.

An apparatus is disclosed for use with an electronic device for alignment of a medical tool for positioning a surgical hardware device. The apparatus includes a case to secure the electronic device such that the electronic device is secured to the case and does not move relative to the case. The case includes an opening to couple with at least a portion of the medical tool. The electronic device is secured relative to the medical tool through the coupling of the case to the at least the portion of the medical tool. The electronic device simulates a three-dimensional position of the surgical hardware device in a body using a diagnostic representation of at least a portion of the body, and the electronic device is secured in the case and coupled to the medical tool assists with the alignment of the medical.
