  • Patent number: 10384082
    Abstract: Disclosed is a method for determining a deviation of the position of an anatomical body part relative to a predetermined position defined by a radiation treatment plan. A monitoring image is taken of the anatomical body part at the instant that a predetermined control point defined in the treatment plan has been reached. The monitoring image is compared to a simulated image simulated from a planning image of the anatomical body from the perspective of a monitoring camera used to generate the monitoring image. The comparison allows for a determination of whether there is a positional deviation.

  • Publication number: 20190156497
    Abstract: The present invention relates to a method for setting up a patient for radiotherapy, wherein the patient is scanned prior to therapy in both, a free-breathing state and a DIBH-state for which the patient performs a so-called “deep inspiration breath-hold”. The obtained data is registered to a CT-dataset which forms the basis for a treatment plan. The patient is then set up with respect to a radiation treatment apparatus based on the data obtained for the free-breathing state.

  • Publication number: 20190156478
    Abstract: The present invention involves positionally identifying several anatomical structures of interest of a patient's anatomy on images which have been acquired at different points of time. For each anatomical structure a separate image fusion transformation between these images is performed. For at least one of the image fusion transformations it is then determined whether this transformation is within a predetermined threshold, wherein for this determination, at least one further image fusion transformation of another anatomical structure is taken into account.

  • Patent number: 10272266
    Abstract: The present invention relates to correlating a position of a radiation beam with a position of a target to be irradiated which is contained in a structure having a repetitive motion comprising a plurality of successive motion cycles. External position data is acquired, which describes a position the structure during different motion cycles and/or time periods. Target data is acquired, which describe a position of the target during the motion cycles and/or time periods. A correlation model is generated, which correlates the external position and the target position. A predicted target position during a motion cycle is determined based on the correlation model and acquire external position data. Primary verification data is determined that describes an difference between actual and predicted target position. When the prediction is accurate, a further prediction and verification of the target position in later motion cycles can be performed.

  • Publication number: 20190111279
    Abstract: A method and system supports pre-positioning a patient for treatment by radiotherapy or radiosurgery. The disclosed method encompasses comparing an image of a reference structure having a known position relative to an anatomical body part of a patient, such as a live thermal/infrared image of the reference structure, to a predetermined medical image of the reference structure associated with a known position relative to a reference position, such as a known isocenter of a radiotherapy or radiosurgery apparatus. On that basis, it is determined whether the reference structure has moved relative to the reference position. A decision may be made to determine whether the reference structure and therefore the patient has been correctly positioned and/or kept in his desired position relative to a treatment device, and to compensate for any possible positional deviation by moving the patient.

  • Publication number: 20180344265
    Abstract: The presently described method is directed to determining a way of positioning a patient before execution of a medical procedure involving irradiating the patient with ionizing treatment radiation based on comparing medical images of the patient with a pre-acquired medical image. The planning computed tomography is searched for an image of the reference stricture in order to determine the position of the patient relative to a patient support device. A retroreflective marker device, having a known and advantageously fixed position relative to the base plate, is detected by a navigation system operatively coupled to a motor of the support device. Based on the detected position of the marker device, the motor of the support device is activated to drive the patient into a desired position relative to beam direction along which the treatment radiation is to be issued towards the patient to execute the medical procedure.
