A radiotherapy control apparatus includes a fluoroscopic image acquisition unit to acquire fluoroscopic images of markers in a patient from a single fluoroscopic imaging device, a projection line calculation unit to identify projected positions of the markers on the fluoroscopic image and calculate equations of projection lines linking these projected positions and a focus position of the imaging device, an inter-marker distance acquisition unit to acquire a distance between each pair of the markers, a marker position calculation unit to calculate current positions of the markers based on the equations and the distances, and a therapeutic radiation emission determination unit to determine whether to emit therapeutic radiation based on the current positions of the markers.
