    Abstract: A system for detecting a position of an object such as a surgical tool in an image guidance system includes a camera system with a detection array for detecting visible light a processor arranged to analyze the output from the array. Each object to be detected carries a single marker with a pattern of contrasted areas of light and dark intersecting at a specific single feature point thereon. The pattern includes components arranged in an array around the specific location arranged such that the processor is able to detect an angle of rotation of the pattern around the location and which are different from other markers of the system such that the processor is able to distinguish each marker from the other markers.

    Abstract: Automatic registration of an MR image is carried out in an image guidance system by placing MR visible markers at known positions relative to markers visible in a camera tracking system. The markers are carried on a common fixture which is attached to a head clamp together with a reference marker which is used when the markers are covered or removed. The tracking system includes a camera with a detection array for detecting visible light a processor arranged to analyze the output from the array. Each object to be detected carries a single marker with a pattern of contrasted areas of light and dark intersecting at a specific single feature point thereon with an array around the specific location to allow the processor is able to detect an angle of rotation of the pattern and to distinguish each marker from the other markers.

    Abstract: Radiation therapy of a lesion within a patient is guided to take into account movement of the lesion caused by respiration and/or cardiac effects by using MRI to image the patient while on the treatment support to obtain a series of images of a location of the lesion within the patient while obtaining data relating to respiration and/or cardiac function of the patient to generate lesion movement data as a function of respiration and/or cardiac function. After the magnet is removed from the bunker, during the radiation therapy, real time data relating to respiration and/or cardiac function of the patient is used to guide the radiation therapy using the lesion movement data obtained during the imaging.

    Abstract: A patient table for a common imaging system including Magnetic Resonance and X-ray retains the patient stationary in position prior to, during and subsequent to the imaging and includes a base, a patient support portion cantilevered from the base and a mattress. The RF posterior coil portions for the head and for the chest can be inserted into and removed from an operating position underneath the head and chest of the patient while patient remains supported. The chest coil is inserted from one edge in a cavity in the mattress which is reinforced by a sleeve. The signal communication cable from the chest coil is routed in front of the mattress and over the mattress so as to not to be exposed at the sides. The head coil is carried on a base plate of the patient support alongside the head support which remains in place.

    Abstract: In a MRI system housed within a room there is provided a movable magnet and additional components for other procedures on the patient, a control system is provided for the relative movement of the magnet and components. This includes a plurality of magnetic field sensors mounted on the components for measuring the magnetic field at the location of the component and an optional camera positioning system so that the control system can estimate relative positions of the components relative to the magnet from the sensed field strengths from the set of sensors to avoid collisions during the movements.
