Tissue protection systems and methods
A probe configured to deliver energy to a first tissue is placed in the first tissue, and an imaging device is configured to image a second tissue with the probe placed in the first tissue. Image data from the second tissue is processed to evaluate the effect of the energy source on the second tissue. In some embodiments, the image data from the second tissue is used to adjust the energy to the first tissue, for example by increasing or decreasing the energy to the second tissue. In some embodiments, image data from the first tissue or the second tissue or force sensor data from the probe is used to evaluate placement of the probe in the first tissue, and the placement of the probe in the first tissue adjusted to decrease tissue alterations of the second tissue related to probe placement in the first tissue.
