The present invention relates to a head immobilization system for immobilizing a patient's head in a supine position of the patient, the system comprising: a support rail structure adapted to be coupled to a patient rest and extending at least on both lateral sides of the patient's head, a mask frame adapted to be coupled to at least one deformable upper mask sheet, wherein the mask frame is releasably connected to the support rail structure via a first interface section and a second interface section, with at least two pins protruding from the first interface section in a first direction, and at least two pin-receptions provided at the second interface section, wherein each one of the pin-receptions receives one of the pins, and a catch-mechanism for each pin-reception and each corresponding pin, which allows the pin to be pushed further into the pin-reception in the first direction, but which interlocks in case of an attempted withdrawal of the pin from the pin-reception in a second, opposite direction.

A stereotactic device for primate brains indicates a brain coordinate reference point of a primate using a simulator for indicating a brain coordinate reference point, thereby providing an initial setting to a zero point corresponding to the brain coordinate reference point. The brain coordinate reference point is conveniently and accurately indicated without relatively expensive equipment, such as a magnetic resonance imaging (MRI) scanner, to determine brain coordinates of the primate, so that a targeting procedure can be conducted on the brain.

A cone-beam computed tomography (CBCT) system employs a large area detector and a cone-beam radiation source to allow for acquisition of projection images in about 180 degrees plus a fan angle to provide a complete data set for CBCT reconstruction to generate an image volume with a field of view (FOV) of at least about 20 cm.

A medical system comprises a control system and a display device coupled to the control system. The control system comprises a processor and a memory comprising machine readable instructions that, when executed by the processor, cause the control system to generate a primary image of an anatomic structure and manipulate a therapeutic instrument to deliver a therapy to the anatomic structure. The control system also determines an effect of the therapy on the anatomic structure and displays a representation of the effect of the therapy in an auxiliary image registered with the primary image of the anatomic structure.

An apparatus for providing at least one treatment to at least one tissue having a first structural arrangement configured to expand a first portion at a distal end of the apparatus, a second structural arrangement configured to expand a second portion at the distal end and at least one lumen associated with at least one of the first structural arrangement and/or the second structural arrangement. The first structural arrangement and/or the second structural arrangement can be configured to position the at least one lumen at a particular position with respect to the tissue. A tip is configured to aid in the insertion of the apparatus into the tissue(s).

A retractor system for use in medical procedures is connectable to a head fixation device. The retractor system includes a support assembly and an accessory that is mountable thereto. The support assembly is coupled with the head fixation device such that a position of the support assembly is adjustable relative to the head fixation device. The support assembly includes an upright support and a rod having a non-circular profile. The support assembly and rod are selectively and adjustably coupled to one another via a coupling assembly. The coupling assembly includes a pair of resilient members having contacting and non-contacting surfaces within bores of the resilient members. The accessory and rod are selectively and adjustably coupled to one another via another coupling assembly that comprises locking features operable to selectively engage and disengage the accessory with the rod.

A headrest for an immobilization system for immobilizing at least a part of a patient is provided. The headrest includes a supporting structure and a sheet-like formed elastic panel attached to the supporting structure on at least two opposite sides of the elastic panel. The elastic panel is configured to support at least a part of a head and/or at least a part of a neck of a patient, wherein at least a part of the elastic panel is stretchable and configured to stretch when said at least part of the head and/or neck of the patient is arranged on the elastic panel, such that a shape of said at least part of the elastic panel is formed corresponding to a shape of said at least part of the head and/or neck of the patient.

A base frame includes a base frame body and a connector. The base frame body has an opening therein. The connector is disposed at the opening of the base frame body to seal the opening of the base frame body, and the connector is made of an insulating material.

Surgical systems and methods for an MRI suite include a housing residing in an MRI scanner room of the MRI suite. The housing comprises a plurality of motors coupled to at least one motor driver (in the same or a different housing); and a plurality of elongate cables, one coupled to one of the plurality of motors residing in the same housing or a different housing. The elongate cables comprise MRI compatible material and having a length in a range of about 24 inches and 60 inches. One of the cables couples to one of the motors at a first end portion and a corresponding one actuator of the actuators of a trajectory guide at a second end portion.

Embodiments of the present disclosure provide a method and an apparatus of locating a tumor. The method includes: obtaining a position of a positioning mark before the patient's head moves, a position of a positioning mark after the patient's head moves, and a position of the tumor before the patient's head moves, wherein the positioning mark is disposed at a preset position of the body surface of the patient's head; determining a position of the tumor after the patient's head moves according to the position of the positioning mark before the patient's head moves, the position of the positioning mark after the patient's head moves, and the position of the tumor before the patient's head moves.
