An apparatus for treatment planning and/or treatment setup includes: a simulator configured to obtain a first model representing a first component of a medical system, and virtually move the first model to simulate a movement of the first component of the medical system; an analyzer configured to determine imaging waypoints during a treatment process based on the virtual movement of the first model; and a graphic generator configured to generate a graphic based on the determined imaging waypoints.

Imaging waypoints for radiation treatment

Collision free regions are predetermined for one or more class solutions. Each class solution has defined limits for allowed field geometry variations. Collision free regions in planning can be defined as a set of allowed isocenter positions relative to a fixation device. The collision free regions may be visualized by a user to plan for field geometry and isocenter position tradeoffs. Collision free regions in delivery can be defined as a set of allowed couch support coordinates. The treatment fields in a radiation treatment plan can be checked against the collision free regions in delivery to determine whether they will pose any collision risks.

Radiation treatment planning and delivery using collision free regions

An outline of at least a patient on a patient support is determined. Based on at least one image of the patient, a plurality of orientations of the patient support and of at least one device are determined. The at least one device is capable of delivering a radiation treatment to the patient or of performing imaging associated with the radiation treatment. Based on the outline and the plurality of orientations of the patient support and of the at least one device, a clearance zone that no portion of the at least one device will occupy when the at least one device or the patient supported by the patient support is in motion is calculated.
