  • Patent number: 9456947
    Abstract: A head positioning device for use in radio therapy is described for positioning a patient's head. The head positioning device comprises a head plate for supporting a patient's head; a base plate for connection to a mechanical couch; and a head plate adjustment assembly connecting the head plate to the base plate wherein the head plate adjustment assembly is arranged to vary the relative pitch, yaw and roll of the head plate relative to the base plate. The head positioning device is arranged to be attached to a mechanical couch with the head plate and the head plate adjustment assembly cantilevered off the end of the couch and the head plate adjustment assembly suspended beneath the head plate and the base plate.
    Type: Grant

  • Patent number: 6484332
    Abstract: A patient transfer system is provided for quick, easy and comfortable movement of a patient between horizontal and vertical positions and between lateral locations for medical procedures. The system includes a gurney with a patient positioning board pivotally mounted thereon for movement between horizontal and upright positions. The board is adapted to receive a patient mold. A footrest is provided at the lower end of the board such that a patient can step onto the footrest when the board is in the upright position and lean against the board. The board is then lowered to a horizontal position on the gurney. The gurney can be wheeled into position adjacent a treatment table in a treatment room, such as for radiation therapy, and docked to the table.

  • Patent number: 6364529
    Abstract: The quality assurance phantom for intensity-modulated radiation therapy is adapted for use with multiple dosimetric devices, such as ion chambers, MOSFET's, radiochromatic film, and TLDs. The phantom includes a base to which a static block is fixed. A dynamic block is mounted on the base and is adjustably spaced from the static block. A plurality of film dividers are sandwiched between the blocks. After film is inserted between the film dividers, the blocks are clamped together. The static and dynamic blocks include a plurality of cavities for receiving various dosimeters. The dosimeters are interchangeable within the cavities, so as to enhance the versatility of the phantom.
