1. A system, comprising:
a radio-frequency (RF) interrogator system;
one or more first RF target devices for coupling to a patient support for supporting a patient with respect to whom a medical device is to perform a task;
one or more second RF target devices for coupling to the medical device; and
a controller configured to, when the one or more first RF target devices are coupled to the patient support and the one or more second RF target devices are coupled to the medical device:
control the RF interrogator system to transmit one or more first RF signals;
control the RF interrogator system to receive:
one or more second RF signals transmitted by the one or more first RF target devices responsive to the one or more first RF signals; and
one or more third RF signals transmitted by the one or more second RF target devices responsive to the one or more first RF signals;
determine, using the received one or more second RF signals, a position of the patient support within an RF interrogator system reference frame;
determine, using the received one or more third RF signals, a first position of the medical device within the RF interrogator system reference frame;
determine a transformation between the RF interrogator system reference frame and a patient support reference frame; and
determine, using the transformation, a second position of the medical device within the patient support reference frame.
