摘要： Apparatus for radiation therapy combines a patient table, an MRI and a radiation treatment apparatus mounted in a common treatment room with the MR magnet movable from a position outside a radiation shielded door to an imaging position. An RF-shielded door is movable between a position, separating part of the treatment apparatus from the magnet and an open position allowing access of the patient to the treatment apparatus. In one configuration there is a row of treatment rooms and the magnet is mounted to move along a passageway outside the row of radiation shielded doors of the rooms.

摘要： 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.

摘要： Radiation therapy of a lesion in a part of a patient is carried out by maintaining the patient on a patient support table in fixed position using an immobilization device while the table is rotated between a magnetic resonance imaging system, a CT imaging system for generating a 360 degree scanned image of the patient at the location of the lesion and the radiation therapy system for generating a beam of radiation for treatment of the lesion and for scanning the beam 360 degrees around the lesion. The MR image locates the lesion and the CT system is used to calculate the treatment. Registration between the MR image, the CT image and the radiation treatment is provided by the fixed position of the part of the patient on the table which is held fixed using an immobilization system suitable for the part concerned which may include a molded head mask where the head is involved.

摘要： Signals in an RF field, such as that of an MRI system, are communicated through an inner conductor having an outer shield with a dielectric material therebetween and an outer cable jacket. Current in the shield caused by the RF field from the transmit body coil is reduced by providing a second dielectric material around the shield conductor and a plurality of segmented shield conductor portions formed of non-magnetic braid or wrapped non-magnetic foil tape outside the second dielectric material and inside the jacket at spaced positions along the cable, with the portions being electrically separated from each other and from the shield so that the segmented shield conductor portions act to shield the outer shield conductor to reduce the generation of current thereon while the electrical separation of the segmented shield conductor portions each from the others prevents the generation of a current along the portions.

摘要： 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.

摘要： In MR imaging in a suite of rooms including a diagnostic room and a second surgical room, the magnet includes a diagnostic table separable from a docking station of the magnet and the second room includes a second surgical table. An imaging control computer controls operation of the imaging system and a movement control computer controls operation of the magnet moving system and the patient support table. During imaging in the surgical room, the diagnostic table is separated and docked at a secondary docking station while an emulating computer system cooperate with the imaging control computer system by emulating outputs from the disconnected diagnostic table for controlling operation of the imaging system.

摘要： Apparatus for radiation therapy combines a patient table, an MRI and a radiation treatment apparatus mounted in a common treatment room with the MR magnet movable through a radiation shielded door to an imaging position. An initial MR image and an initial X-ray image is used to generate an RT program for the patient to be carried out in a plurality of separate treatment steps. Before carrying out the procedure, a registration step is performed using a phantom by which X-ray images are registered relative to MR images to generate a transformation algorithm required to align the MR images of the part of the patient relative to the X-ray images. Prior to each separate treatment step a current MR image of the part of the patient is obtained and the transformation algorithm data is used from the current MR image is used in guiding the RT treatment step.

摘要： An RF coil used for MR imaging is designed so that it remains in place in the field of view of an X-Ray imaging system and comprises a support board on which copper conductive traces and copper printed capacitors are carried. The attenuation of the X-Rays caused by the copper traces is visible in the radiation image but this is compensated by arranging the non-conductive material of the support board such that the attenuation of substantially the whole of the RF coil located within the field of view is substantially constant throughout the field of view.

摘要： 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.

摘要： In a method for guiding brachytherapy radiation treatment the patient is supported on a table and an MR magnet is brought into the treatment bunker through doors for imaging while the after-loader for the radiation source delivery is stored away in a storage location outside the RF shield. A safety system controls movement of the after-loader and the magnet. Images of the patient obtained while the patient is on the table are used to locate the applicator with respect to the lesion and organs-at-risk. The MR and X-ray compatible patient support table with MR coil integration includes a removable end-extension, which provides pelvic access for applicator insertion.
