The invention relates to a method for estimating positions of a subject's feet and centre of mass relative to each other during gait. The method comprises a step of collecting measurement data from a first inertial measurement unit located at a first foot or first shank of the subject, from a second inertial measurement unit located at a second foot or second shank of the subject, and from a third inertial measurement unit located at a pelvis of the subject. Further, the method includes a step of evaluating relative positions of the first and second foot and the center of mass of the subject over time, using the measurement data of the first, second and third inertial measurement unit. The method may include a step of applying the assumption that a moment around a center of mass of the subject vanishes for determining an estimation of relative foot positions.

Disclosed herein are methods for patient setup and patient target region localization for the irradiation of multiple patient target regions in a single treatment session. Virtual localization is a method that can be used to register a patient target region without requiring that the patient is physically moved using the patient platform. Instead, the planned fluence is updated to reflect the current location of the patient target region by selecting a localization reference in the localization image, calculating a localization function based on the localization reference point, and calculating the delivery fluence by convolving the localization function with a shift-invariant firing filter. Mosaic multi-target localization partitions a planned fluence map for multiple patient target regions into sub -regions that can be individually localized. De-coupled multi -target localization involves generating a separate planned fluence map for each target but constraining a cumulative fluence map to ensure dosimetric goals are met.
