Table 2 Summary of spatial resolution of intraoperative gamma detectors used in the present study and detectors reported in the literature [27, 30–32, 34, 35]. Zaburlini et al. [34] and Haigh et al. [32] included detector B in their evaluations and their results for this detector is shown separately
