| Popis: | Intraoperative gamma probes have been widely used in surgery oriented to locate the sentinel lymph nodes in breast cancer and malignant melanoma during the surgery. In this paper, a surgical gamma probe using TlBr as a crystal semiconductor detector was developed. The performance of the probe with a maximum sensitivity of 10 cps/kBq and 11 mm of spatial resolution in 10 mm depth shows that the TlBr crystal is suitable to be used in a sentinel lymph node gamma probe. The final probe size was 12.7 mm diameter, 170 mm long and the detection performance met the necessary requirements to be used in radioguided surgery. |
