Image-guided therapy of a tissue
In one aspect, the present disclosure relates to a head fixation apparatus including a number of support posts, and a curved ring portion including a number of connectors configured to adjustably and releasably mount support posts on the lower ring portion, such that the support posts are selectively mounted to a subset of the connectors in a customized arrangement for a patient. The apparatus may include a ring mount configured for fixation to a platform, including a curved channel substantially matching a curvature of the curved ring portion, and a mount locking mechanism for locking the curved ring portion within the channel of the ring mount. The curved ring portion may be configured to rotate within the channel of the ring mount while the ring mount is fixed to the platform, an angular head position of the patient being selectably adjustable while the patient is laying on the platform.
1. A system for delivering intracranial energy emission therapy comprising: a probe for delivering intracranial energy emission therapy to a patient;
a probe driver including a commander unit and a follower for receiving the probe the follower operably coupled to the commander unit and configured to control a rotational and longitudinal movement of the probe within the patient;
an interface platform operably coupled to and configured to monitor the probe and probe driver; a head fixation device including a plurality of support posts for supporting a head of the patient, a curved ring portion including a lower ring portion, the curved ring portion comprising a plurality of connectors configured to adjustably and releasably mount the plurality of support posts on the lower ring portion, such that the plurality of support posts are selectively mounted to a subset of the plurality of connectors in a customized arrangement for the patient, a ring mount configured for fixation to a platform, wherein the ring mount comprises a curved channel substantially matching a curvature of the curved ring portion and a mount locking mechanism for locking the curved ring portion mounted within the channel of the ring mount, wherein, the curved ring portion is configured to rotate within the channel of the ring mount while the ring mount is fixed to the platform, an angular head position of the patient being selectively adjustable while the patient is laying on the platform, and the mount locking mechanism is configured to lockably engage the curved ring portion within the channel of the ring mount upon positioning of the angular head position of the patient; and
a workstation operably coupled to the probe and configured to output signals to an MRI system to initiate imaging tasks associated with the delivery of the intracranial energy emission therapy by the probe.
2. The system of claim 1 wherein the system is indicated for use to ablate, necrotize, carbonize and/or coagulate a targeted intracranial tissue.
3. The system of claim 1 wherein said probe is configured to deliver HIFU thermal therapy to the patient.
4. The system of claim 1 wherein said probe is a laser probe configured to deliver laser-based thermal therapy to the patient.
5. The system of claim 4 wherein the laser-based thermal therapy includes light from the ultraviolet, visible, near-infrared, mid-infrared and far-infrared spectrums.
6. The system of claim 4 wherein said laser probe is selected from gas lasers, chemical lasers, dye lasers, metal-vapor lasers, solid-state lasers, semiconductor lasers and free electron lasers.
7. The system of claim 1 wherein the longitudinal movement of the probe is from 20 mm to 150 mm.
8. The system of claim 1 wherein the rotational movement of the probe is from 300 degrees to 360 degrees.
