摘要

This paper describes the design of a fast imaging system aimed at providing the accurate location of the centroid of a sentinel lymph node. Through the proposed use of a new 8Omm diameter multi-pixel hybrid photo-diode, equipped with a fibre-optic window, a CsI(Tl) scintillation crystal and a specially optimised collimator, we expect to achieve a precision of ±3mm within 20 s for the location of a lymph node. It has been assumed that the affected gland has a 10mm diameter and had accumulated 3 250L藽i of 99{sup left}Tc through drainage of the region of the breast. The paper discusses the likely imaging quality of the larger tube based on measurements made with a smaller prototype detector. The design of two collimators is presented; one to provide a rapid location of the centroid of the SLN and the other to provide the surgeon with a measure of the depth of the potentially infected organ. A method for relating the image information to the patient's anatomy to guide the surgeon is also presented.
