Abstract: An apparatus for prompting a patient includes a structure configured to be mounted to a patient support, a screen coupled to the structure, and a projector located at a distance away from the screen. A method of prompting a patient that is being supported on a patient support includes adjusting a position of a screen relative to a projector, the screen having a surface, placing the screen in front of the patient such that the patient can see the surface, and providing an image on the screen using the projector.

Abstract: A marker system includes a marker, and a positioner coupled to the marker, the positioner configured to position the marker from a first predetermined position to a second predetermined position. A method of providing a marker system includes obtaining a first data representative of a first predetermined position, obtaining a second data representative of a second predetermined position, and moving a set of one or more markers from the first predetermined position to the second predetermined position, wherein the set of one or more markers is moved using a positioner. A method of using a marker system includes detecting a marker when the marker is located at a first position, moving the marker from the first position to a second position using a positioner, and detecting the marker when the marker is located at the second position.

Abstract: A marker system includes a structure having a first surface and a second surface, a first marker located on the first surface, and a second marker located on the second surface, wherein the first marker and the second marker are arranged so that they face approximately a same direction, and so that they can be simultaneously viewed by an optical device, and wherein a first distance between the first marker and the optical device is different from a second distance between the second marker and the optical device when the first and the second markers are simultaneously viewed by the optical device.

Abstract: A calibration device includes a structure, and a target object that is moveably coupled to the structure, the target object being a physical target towards which an alignment device can be aimed. A calibration device includes a block having a first opening, and a target object that is viewable through the first opening. A method of calibrating an alignment device includes determining a target position associated with a machine, placing a target object at the target position, and adjusting the alignment device using the target object. A calibration device includes a target object, the target object being a physical target towards which an alignment device can be aimed, wherein the target object comprises a first feature for indicating a first orientation of the target object.

Abstract: An apparatus and method to implement and control a plurality of minimally invasive therapies in the treatment of a medical condition of a patient based on a treatment plan. The apparatus includes a template which has a plurality of electrically conductive apertures, a plurality of needles which have a plurality of sensors and a processor. At least one of the needles is inserted through and in electrical contact with one of the conductive apertures. The processor is electrically coupled to the template and is configured to send signals to and receive signals from at least one of the sensors of at least one of the needles inserted through one of the conductive apertures. The processor is further configured to process the signals received from the sensor in relation to the treatment plan and to adjust the signals sent to the sensor to control the treatment.
