1. A tethered laparoscopic probe for deployment through a trocar into a cavity of a subject to detect gamma radiation from a radiopharmaceutical administered to the subject, the tethered laparoscopic probe comprising:
a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity, the probe head comprising:
an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation;
a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing; and
a tether coupled to the probe head and for, in use, tethering the probe head through the trocar, wherein the tether comprises a cable for communicating a signal from the gamma radiation detector from the head, and the radiation shielding comprises a tortuous path for an electrical connection through the radiation shielding to the cable to facilitate localization of a source of radiation from the radiopharmaceutical within the cavity.
