Methods and systems of radiosurgical treatment include rotating one or both of a first gantry component and a second gantry component while transmitting a therapeutic treatment beam so as to deliver a therapeutic radiation dose to a target tissue of a patient from one or more arcs extending along a treatment sphere. The first gantry component is rotatable about a first axis and a second gantry component is interfaced with the first gantry component such that rotation of the first gantry component rotates both the first and second gantry components about the first axis. The second gantry component is independently rotatable about a second axis. The method includes coordinating movement of the first and second gantry components along the respective first and second axes so as to allow a trajectory of the therapeutic treatment beam to intersect the target tissue from multiple directions along the treatment sphere.

This invention provides cyclic polypeptide compounds and their uses, specifically disclosing cyclic polypeptide compound A and cyclic polypeptide compound B. Cyclic polypeptide compound A is a compound formed by chelating compound X with a therapeutic radionuclide ion. Cyclic polypeptide compound B is a compound formed by chelating compound X with a diagnostic radionuclide ion. These compounds can be used for the diagnosis and treatment of tumors associated with or mediated by FAP, exhibiting high tumor uptake, long residence times, and broad applicability.

These various embodiments can serve to facilitate optimizing a radiation treatment plan to administer therapeutic radiation to a particular patient using a particular radiation treatment platform (that may include, for example, a medical linear accelerator) located at a facility having a radiation treatment platform user interface. The radiation treatment platform user interface is coupled to a remote user interface via a secure remote connection that does not permit the remote user interface to operate any radiation delivery capability of the treatment platform nor to execute movement of any of the dynamical components and to then conduct two-way communications (which may be encrypted if desired) between the radiation treatment platform user interface and the remote user interface regarding a radiation treatment plan to administer therapeutic radiation to the particular patient using the particular radiation treatment platform, wherein the two-way communications can include a final approval of an optimized radiation treatment plan.

A control circuit (101) may, before administering therapeutic radiation to a particular patient using a particular radiation treatment apparatus (114) with an optimized radiation treatment plan, access (202) an electronic portal imaging device prediction neural network that was trained with a plurality of training items each comprising information regarding a previous radiation treatment plan and corresponding electronic portal imaging device signal information and then input (203) information regarding the optimized radiation treatment plan to the electronic portal imaging device prediction neural network and output a corresponding predicted electronic portal imaging device signal.

The invention relates to a magnetic resonance imaging radiotherapy system capable of reducing interference on treatment radiation. The system comprises: a magnetic resonance imager (110) comprising a magnet (120) surrounding an aperture (130); a radiation therapy device (140) configured for radiating a therapy beam (160) having a respective radial beam path towards the aperture (130) from a plurality of locations around a longitudinal axis (150) of the aperture; a cold head (170) positioned outside the beam path; and a thermally conductive cooling section (180) in thermal connection with the cold head (170). The cooling section (180) extends azimuthally about a longitudinal axis (150) of the bore. The cooling section (180) is positioned to intersect the beam path, and the width (w) of the cooling section is greater than the maximum width of the treatment beam (180). Preferably, the attenuation of the treatment beam (160) caused by the cooling section (180) is constant between respective beam paths from different positions around the longitudinal axis (150) of the bore.

A method for performing ablative radiotherapy includes registering a first coordinate system of a tracking system for tracking a distal end of an intra-body catheter with a second coordinate system of a beam-directing system, tracking the location of a distal end of the catheter, receiving instructions from a user to ablate target tissue within the body with the beam-directing system and based on the registration and the tracking, aiming the beam-directing system at the target tissue so as to facilitate directing the therapeutic beams of radiation at the target tissue.
