    • PURPOSE: A position determination apparatus for determining a position of a patient bed and a determining method thereof are provided to enhance accuracy regardless of an operator's proficiency in a process for determining the position of the bed. CONSTITUTION: An X-ray emission unit(26) is mounted to a particle beam irradiation system and is movable between a first position and a second position in order to emit an X-ray at the first position. An X-ray entry unit receives the X-ray from the X-ray emission unit and outputs an output signal dependent on the received X-ray. An image information generator(29) is used for generating second image information about a patient's body part by using the output signal of the X-ray entry unit. A processing unit executes a pattern matching process between a part of first image information in a first set area including an iso-center and a part of the second image information in a second set area including a position corresponding to the path of the charged particle beam in order to generate the bed position information.

    • PURPOSE: Particle beam therapy systems and, in particular, a digital imaging system for imaging a target region of a patient's body, are provided to determine the position of the patient relative to a particle beam delivery system to thereby allow the position of the patient to be adjusted into a desired position. CONSTITUTION: An imaging system for a proton beam therapy system having a proton source, a beam delivery system with a nozzle comprises: an imaging beam source mounted on the beam delivery system wherein the imaging beam source is movable between a first position, wherein the imaging source can project an imaging beam along a treatment beam path towards a first side of the patient, and a second position wherein the imaging source is removed from the beam path to thereby allow the proton beam to travel along the treatment path; an imaging beam receiver attached to the gantry so that the receiver is centered about the beam path throughout a plurality of angles of orientation of the gantry wherein the receiver receives the imaging beam after it has passed through a region of the patient that is positioned in the beam path; an image capture device proximate to the receiver, wherein the image capture device directly receives a non-intensified signal from the receiver and produces a patient orientation image of the region of the patient's body that is positioned in the beam path; and a controller which receives both the master prescription image and the patient orientation image, wherein the controller is configured so that one or more rigid structures can be designated on the master prescription image so as to define the relative position of an isocenter to be treated in the patient's body with respect to the one or more rigid structures and wherein the controller is also configured so that the one or more rigid structures can be designated on the patient orientation image so that the controller can determine the relative location of the center of the beam line with respect to the one or more rigid structures and wherein the controller using the relative position of the target isocenter and the beam line center with respect to the one or more rigid structures determine the relative movement between the patient and the gantry required so that the position of the center of the beam line with respect to the one or more rigid structures corresponds to the position of the target isocenter with respect to the one or more rigid structures

    • A data processing method performed by a computer for monitoring the position of a patient, comprising the steps of: acquiring a 3D image dataset of the patient; acquiring an initial real image of the patient from a medical imaging system having a known and fixed location in space, thus defining a known viewing direction of the initial real image in space, the real image being taken at a first point in time; - performing 2D/3D registration by calculating a simulated image from the 3D image dataset which matches the initial real image best, the simulated image having a viewing direction onto the 3D image dataset; storing an initial similarity measure value for the pair of the initial real image and the calculated simulated image; - acquiring a subsequent real image from the medical imaging system taken at a second point in time later than the first point in time; calculating a subsequent similarity measure value for the pair of the subsequent real image and the calculated simulated image; and outputting an indication signal if the difference between the initial similarity measure value and the subsequent similarity measure value fulfills a predetermined criterion.
