Abstract
A method for compensating for dynamic changes in a body of a patient during a controlled interaction with the body includes acquiring data from at least one sensing device disposed on the body and detecting a change along at least one optical fiber of the sensing device caused by dynamic changes associated with the body during the controlled interaction. A respiratory gating signal is generated based on the change along the at least one optical fiber of the sensing device measured over time. The method further comprises controlling relative movement between the body and an interactive device in response to the respiratory gating signal to compensate for the dynamic changes associated with the body during the controlled interaction.
Claims29
A method of compensating for dynamic changes in a body of a patient during an image-guided interaction with a target region of the body, the method comprising:
- acquiring data from an optical fiber-based sensing device disposed on the body, the data representing a change along at least one optical fiber of the sensing device caused by dynamic changes associated with the body during the image-guided interaction;
- determining a position of the target region of the body based on the change along the at least one optical fiber of the sensing device;
- controlling a scanning device, based on the change along the at least one optical fiber of the sensing device caused by the dynamic changes associated with the body, to acquire image data of the target region of the body during the dynamic changes;
- and
- controlling an interactive device, based on the determined position of the target region, to compensate for the dynamic changes during the image-guided interaction by limiting relative movement between the target region of the body and the interactive device.
