Towards 3D thyroid imaging using robotic mini gamma cameras

Thyroid imaging using radioactive tracers is a common task in clinics and is usually performed using 2D gamma cameras (scintigraphy). In this work we present a setup for 3D imaging of the thyroid using a mini gamma camera mounted on a robotic arm. Several images are acquired moving the mini gamma camera along a trajectory around the thyroid. Afterwards, a tomographic reconstruction computes a 3D SPECT-like image of the thyroid. First results are shown of a thyroid phantom using a conventional statistical reconstruction scheme (MLEM) and using a sparse regularization approach based on total variation.
