A subject support (118) for an imaging system (100) includes a moveable portion (122) that includes a surface (204) on which the subject is loaded and that is configured to move into an examination region of the imaging system where the subject is to be scanned. The support further includes a scan position identifier (126) that generates a signal indicative of at least one of a start scan position or an end scan position for a predetermined region of interest of the subject based on a location of the region of interest on the moveable portion of the subject support for an arbitrary relative position of the moveable portion with respect to the examination region.
