A locator for the placement of a fiducial support device for brachytherapy may be used to perform a brachytherapy treatment in which one or more radioactive seeds are implanted into a treatment region of a patient.

A brachytherapy template adaptor for performing brachytherapy procedures using needles smaller in diameter than the template is designed to accommodate. Additionally, a kit for adapting a brachytherapy template is provided.

Braces to reduce bending of a brachytherapy needle during insertion into a patient, as well as methods of using the needle braces and kits useful therefor.

A system for automatically identifying a needle insertion location from a medical diagnostic image, such as an MRI image, and providing a visual indication of the needle insertion location is disclosed. A grid plate is located proximate to an anatomical region and is preferably incorporated in an MRI support structure utilized to immobilize the anatomical region. An MRI scanner obtains an MRI image of the anatomical region, and an MRI technician places a marker on the MRI image, identifying the needle insertion location. The MRI image and the marker are transferred from the MRI scanner to another device, such as a tablet computer, which is configured to convert the MRI image and the marker to coordinates and an insertion depth. A visual indicator is located proximate to or integrated with the grid plate that provides the needle insertion coordinates and insertion depth to the MRI technician.

A mechanism facilitates the insertion of radioactive sources/source strands into soft tissue, such as breast tissue, that improves the reproducibility of the procedure and ensures that the sources are reliably and consistently inserted in an exact position per a patient prescription treatment plan from patient to patient as well as improve the ease-of-use of the device and procedure.

The present invention relates to an applicator device (10; 10; 10″) for interventional radiotherapy treatments (brachytherapy), perineal intervention and/or diagnostic procedures on a patient, comprising a substantially plate-like and on the whole T-shaped main body (1; 1′; 1″), which main body (1; 1′; 1″) comprises two peripheral portions (19) having a profile with curved, preferably concave, route, each one intended to abut on a patient's leg.

The present invention provides a brachytherapy applicator device having: an elongate body defining a plurality of brachytherapy needle channels, each adapted and configured to receive a brachytherapy needle; a proximal end defining a plurality of proximal openings, each in communication with one of the plurality of brachytherapy needle channels; and a distal end defining a plurality of distal openings, each in communication with one of the plurality of brachytherapy needle channels, wherein at least some of the plurality of brachytherapy needle channels are curved away from a central axis of the elongate body at the distal end such that a brachytherapy needle inserted therethrough will engage with tissue lateral to a cross-sectional profile of the distal end of the elongate body.

A template assembly including a first grid (22) for placement on a first side of a body organ, defining a plurality of apertures (329) adapted to receive elongate applicators (410), a second grid (24) for placement on a second side of a body organ, defining a plurality of apertures (34), adapted to receive applicators passing through apertures of the first grid and the body organ and at least one frame (26) defining a large hole (72), positioned between the first and second grids and configured to grasp the body organ.

A delivery system and method for radiation shielded brachytherapy has a drive assembly, and a plurality of shield assemblies, pivotally mounted to the drive assembly, each having a tubular body defining an outer surface and a bore longitudinally extending between opposite ends of the tubular body. Each of the shield assemblies has radiation shielding material extending about a circumferential portion of the tubular body and disposed between the outer surface and the cavity. An interlocking system is operatively mounted to the rotating assembly, and engages a group of the plurality of shield assemblies. The interlocking system is configured for transmitting a rotational input received from a driving mechanism to the group of shield assemblies, for synchronously rotating each shield assembly of the group about their respective longitudinal axis.

The present disclosure provides a neutron capture therapy system, including an accelerator for generating a charged particle beam, a neutron generator for generating a neutron beam having neutrons after irradiation by the charged particle beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly includes a moderator and a reflecting assembly surrounding the moderator. The neutron generator generates the neutrons after irradiation by the charged particle beam. The moderator moderates the neutrons generated by the neutron generator to a preset energy spectrum. The reflecting assembly includes a reflecting assembly to deflected neutrons back to the neutron beam and a supporting member to support the reflectors. A lead-antimony alloy is for the reflecting assembly to mitigate a creep effect that occurs when only a lead material is for the reflectors, thereby improving the structural strength of a beam shaping assembly.
