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 structure 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.

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.

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.

Abstract: The present disclosure is directed to a system, method and apparatus for tracking an anatomical body part in a series of x-ray images. The anatomical body part moves due to a vital movement, such as breathing motion of the thorax. The anatomical body part is defined in a CT image acquired beforehand and is associated with a known movement phase during the vital movement. The series of x-ray images of the moving anatomical body part is taken. The movement phase associated with each one of the x-ray images is determined. In one implementation, the system may track the body part movement using external infrared-reflecting markers and a navigation system while taking a series of x-ray images and time-stamping the x-ray images and the positional information for the body part. The time stamps relate each one of the x-ray images with a specific movement phase of the body part. The specific x-ray image being associated with the same movement phase as the CT image is determined and the representation of the anatomical body part defined in the CT image can be determined in the x-ray image by comparing the CT image with the specific x-ray image. The specific x-ray image may be compared to the other x-ray images to find the anatomical body part in those x-ray images and preferably highlight it to be easily recognized by a user.

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.
