A robotic patient positioning assembly including a patient treatment couch, and a robotic arm coupled to the patient treatment couch. The robotic arm is configured to move the patient treatment couch along five rotational degrees of freedom and one substantially vertical, linear degree of freedom.

Robotic arm for patient positioning assembly

A patient positioning assembly is described. The patient positioning assembly including a plate member rotatably mounted on a base member, and an arm extending between a first end and a second end, wherein the first end is rotatably attached to the plate member. The patient positioning assembly further including a support device rotatably attached to the second end of the arm to support a patient thereon, with the support device is configured to move the patient in at least five degrees of freedom.

Patient positioning assembly

A method and apparatus of a positioning system are described to position an upper-half of a body relative to a head-end of a couch. The positioning system may be a patient positioning system and may include a treatment couch, a leg rest coupled to the treatment couch, and a drive mechanism coupled to the leg rest. The patient positioning system may also include a treatment couch, having a base portion of a treatment couch and plurality of detachable portions of the treatment couch. The plurality of detachable portions to adjust a height of the treatment couch to accommodate differing heights of patients.

Method and apparatus for patient loading and unloading

A method for precision registration of X-ray images to cone-beam CT scan for image-guided radiosurgery includes acquiring 2-D pre-treatment X-ray images of a region of interest, acquiring a 2-D X-ray image of the region of interest at approximately a time of treatment, registering the 2-D X-ray image with a corresponding 2-D pre-treatment X-ray image to obtain a 2-D registration result at approximately the time of treatment, and converting the 2-D registration result into a 3-D tracking result to track the region of interest.

Precision registration of X-ray images to cone-beam CT scan for image-guided radiation treatment

A robotic patient positioning assembly for therapeutic radiation treatment includes a robotic positioning device for moving and supporting the patient during treatment, a sensor system for detecting the position of the robotic positioning device, and a controller operatively connected with the sensor system for receiving position data of the robotic positioning device and operatively connected to the robotic positioning device for controlling the motions of the robotic positioning device. The controller is adapted for controlling the motion of the robotic positioning device in response to information representative of the position of the robotic positioning device received from the sensor system, so that the treatment target within a patient loaded on the robotic positioning device is properly aligned with a radiation source of a therapeutic radiation treatment system.

A method of automatically identifying a region of differing intensity in a functional image is described.

Inverse planning using optimization constraints derived from image intensity

An image-guided radiation treatment system includes a robotic positioning system and a tracking system that enables a radiation target to be imaged and aligned at one location and treated at another location by transferring positional data from the imaging system to the positioning system and the radiation treatment system.

Non-collocated imaging and treatment in image-guided radiation treatment systems

An interface is provided to a user to perform a plurality of treatment planning operations associated with the treatment plan before the treatment plan is optimized. The treatment planning operations include at least one of selecting a treatment planning parameter or inputting data corresponding to the treatment planning parameter. One or more templates containing one or more pre-defined treatment planning parameters are provided to the user to enable the user to skip performing one or more of the plurality of operations.

Wizard and template for treatment planning

A method of automatically optimizing an inverse treatment plan by referencing data from an accepted plan library.

Method for automatic anatomy-specific treatment planning protocols based on historical integration of previously accepted plans

A system and method for stereoscopically imaging a patient at multiple locations in a radiation treatment system with variable imaging geometry to enable the delivery of radiation treatments from multiple ranges of treatment angles without obstructing the imaging system or the radiation treatment.

Imaging geometry for image-guided radiosurgery

A respiration phantom that may be used to perform quality assurance on a radiation delivery system. The respiration phantom includes a human-like skeletal structure, at least one deformable component, and a respiration actuator. The deformable component is positionable at least partially internal to the human-like skeletal structure, has a shape resembling an organ of a human anatomy, and attenuates radiation substantially similarly to the organ of the human anatomy. The respiration actuator is positioned to deform the deformable component with a respiration-like motion.
