A system to analyze the geometry of a radiation treatment apparatus, software, and methods are provided. The system includes an apparatus having a rotating assembly and a trackable body or plurality of trackable bodies, to mark a location of a preselected portion of the rotating assembly. The system also includes a trackable reference fixture and can include a constant orientation trackable body. A determiner determines the position and/or orientation of the trackable bodies, the trackable reference fixture, and constant orientation trackable body. The determiner then determines the geometry of the treatment apparatus to analyze a coordinate system used by an operator. The determiner can have a memory and geometry analyzing software stored in the memory to analyze the treatment apparatus geometry.

System for analyzing the geometry of a radiation treatment apparatus, software and related methods

A system, tracker, program product, and methods to facilitate and verify proper target alignment for radiation delivery are provided. The system includes a radiation delivery apparatus having a radiation emitter, a rotating assembly controlled by a controller, and an application computer which provides treatment delivery instructions to the controller. The system also includes a trackable body having a trackable body reference point to be positioned adjacent a surface point of a patient to determine a position of such surface point. The system also includes an apparatus to track a trackable body which has a trackable body detector to detect a position of indicators carried by the trackable body and a trackable body determiner to determine a position of the trackable body reference point. The system also includes a target alignment analyzing computer having memory and target alignment analyzing program product stored therein to aid a user of the system to make and display various patient body-surface related measurements.

System, tracker, and program product to facilitate and verify proper target alignment for radiation delivery, and related methods

A system to monitor a geometry of a treatment apparatus, an apparatus, a trackable assembly, program product, and methods are provided. The system includes a treatment apparatus having a radiation emitter, a rotating assembly controlled by a controller, and an application computer, which provides treatment delivery instructions to the controller. The system can also include a trackable assembly connected to the rotating assembly and having a fixedly connected first trackable body which functions as a reference fixture and a pivotally connected second trackable body which provides data used to determine a rotation angle of the rotating assembly. The system also includes an apparatus to track a trackable body which has a trackable body detector to detect a position of the indicators carried by the first and the second trackable bodies and a determiner to determine and verify the location of the origin of an isocenter coordinate system and to determine rotational path data about the rotating assembly.

System for monitoring the geometry of a radiation treatment apparatus, trackable assembly, program product, and related methods

A system to track a three-dimensional position and an orientation of a movable object and associated methods are provided. The system includes a tracker having an optically trackable body adapted to connect to the movable object. A plurality of optical indicators are connected or mounted to the optically trackable body to form a plurality of geometric figures. A plurality of obfuscating flanges optically separate the optical indicators from each other to prevent each of the optical indicators from becoming optically coincident with another optical indicator when viewed along a preselected viewing path. The system also includes an apparatus to track the tracker having an optical detector to simultaneously detect the three-dimensional position of at least three of the plurality of optical indicators and a determiner to determine the three-dimensional position and orientation of the optically trackable body from the position of the optical indicators.

System and tracker for tracking an object, and related methods

A system and method for aligning the position of a target within a body of a patient to a predetermined position used in the development of a radiation treatment plan can include an ultrasound probe used for generating live ultrasound images, a position sensing system for indicating the position of the ultrasound probe with respect to the radiation therapy device, and a computer system. The computer system is used to display the live ultrasound images of a target in association with representations of the radiation treatment plan, to align the displayed representations of the radiation treatment plan with the displayed live ultrasound images, to capture and store at least two two-dimensional ultrasound images of the target overlaid with the aligned representations of the treatment plan data, and to determine the difference between the location of the target in the ultrasound images and the location of the target in the representations of the radiation treatment plan.
