Characterisation of a hand-held CZT-based gamma camera for ¹⁷⁷Lu imaging.

ABSTRACT:

Background

Currently, hand-held gamma cameras are being developed for ^99mTc imaging, mainly for sentinel lymph node detection. These cameras offer advantages, such as mobility and ease of access, and may be useful also for other applications such as biokinetic studies in animals or for imaging of small, superficial structures in patients. In this work, the suitability of a CZT-based hand-held camera for ¹⁷⁷Lu imaging is investigated. The energy response of CZT-based detectors combined with the multiple photon emissions of ¹⁷⁷Lu poses new challenges compared to ^99mTc imaging, and a thorough camera characterisation is thus warranted.

Methods

Three collimators (LEHR, LEHS, and MEGP) and three energy windows (55 keV, 113 keV, and 208 k
