1. A method of scanning, by a gamma detector, a region of interest (ROI), the method comprising:
detecting gamma radiation for a first time duration by a first gamma detector that faces the ROI from a first direction; and
detecting gamma radiation for a second time duration by a second gamma detector that faces the ROI from a second direction,
wherein the first time duration is longer than the second time duration when attenuation of gamma radiation between the gamma detector and the ROI is higher along the first direction than along the second direction.
