MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY (measurement of bioelectric currents A61B; surgical instruments, devices or methods for transferring non-mechanical forms of energy to or from the body A61B18/00; anaesthetic apparatus in general A61M; incandescent lamps H01K; infrared radiators for heating H05B) ## Abstract Systems and methods for delivering coplanar and non-coplanar medical treatments are described in which a rotating member is engaged with an angularly displaced treatment ring including at least one treatment device, whereby rotation of the rotating member and the treatment ring or treatment device combine to allow non-coplanar therapy to be delivered to a patient. ## Claims ### Claim 1 A medical treatment system comprising: a stand; a rotating member engaged with the stand and configured to rotate in a first rotation plane; a treatment ring configured to rotate in a second rotation plane, the treatment ring engaged with and angularly displaced from the rotating member by a tilt angle, wherein the first rotation plane and the second rotation plane are angularly separated by the tilt angle; at least one treatment device engaged with the treatment ring and configured to deliver therapy to a patient; and wherein rotation of the rotating member causes the at least one treatment device to follow a non-coplanar path for delivering therapy to the patient. ### Claim 2 (depends on 1) The medical treatment system of claim 1 wherein the at least one treatment device is configured to deliver a therapy from the group consisting of radiation therapy, high-frequency focused ultrasound therapy, ablative therapy, laser therapy and radio-frequency therapy. ### Claim 3 (depends on 1) The medical treatment system of claim 1 wherein the tilt angle is variable. ### Claim 4 (depends on 3) The medical treatment system of claim 3 further comprising a beam stopper engaged with the treatment ring and configured to rotate in the second rotation plane, opposite the at least one treatment device. ### Claim 5 (depends on 1) The medical treatment system of claim 1 wherein the tilt angle is fixed. ### Claim 6 (depends on 5) The medical treatment system of claim 5 further comprising a beam stopper engaged with the treatment ring and configured to rotate in the second rotation plane, opposite the at least one treatment device. ### Claim 7 (depends on 1) The medical treatment system of claim 1 wherein a center of the treatment ring defines an isocenter and the at least one treatment device is configured to rotate and deliver therapy to targets displaced from the isocenter. ### Claim 8 (depends on 1) The medical treatment system of claim 1 further comprising at least one imaging device engaged with the treatment ring and located opposite the at least one treatment device. ### Claim 9 (depends on 1) The medical treatment system of claim 1 further comprising at least one imaging device engaged with the treatment ring and located adjacent the at least one treatment device. ### Claim 10 (depends on 1) The medical treatment system of claim 1 further comprising a protective wall around the patient. ### Claim 11 A medical treatment system comprising: a stand; a rotating member engaged with the stand and configured to rotate in a first rotation plane; a treatment ring engaged with and angularly displaced from the rotating member by a tilt angle and having a first axis; at least one treatment device to deliver therapy to a patient, engaged with the treatment ring and configured to rotate around the first axis in a second rotation plane, wherein the first rotation plane and the second rotation plane are angularly separated by the tilt angle; and wherein rotation of the rotating member causes the at least one treatment device to follow a non-coplanar path for delivering therapy to the patient. ### Claim 12 (depends on 11) The medical treatment system of claim 11 wherein the at least one treatment device is configured to deliver a therapy from the group consisting of radiation therapy, high-frequency focused ultrasound therapy, ablative therapy, laser therapy and radio-frequency therapy. ### Claim 13 (depends on 11) The medical treatment system of claim 11 wherein the tilt angle is variable. ### Claim 14 (depends on 13) The medical treatment system of claim 13 further comprising a beam stopper engaged with the treatment ring and configured to rotate in the second rotation plane, opposite the at least one treatment device. ### Claim 15 (depends on 11) The medical treatment system of claim 11 wherein the tilt angle is fixed. ### Claim 16 (depends on 15) The medical treatment system of claim 15 further comprising a beam stopper engaged with the treatment ring and configured to rotate in the second rotation plane, opposite the at least one treatment device. ### Claim 17 (depends on 11) The medical treatment system of claim 11 wherein a center of the treatment ring defines an isocenter and the at least one treatment device is configured to rotate and deliver therapy to targets displaced from the isocenter. ### Claim 18 (depends on 11) The medical treatment system of claim 11 further comprising at least one imaging device engaged with the treatment ring and located opposite the at least one treatment device. ### Claim 19 (depends on 11) The medical treatment system of claim 11 further comprising at least one imaging device engaged with the treatment ring and located adjacent the at least one treatment device. ### Claim 20 (depends on 11) The medical treatment system of claim 11 further comprising a protective wall around the patient.
