Inside-Out Tracking for Flexible Hand-held Nuclear Tomographic Imaging
Tracking systems are used in many medical scenarios for the localization of devices or the patient, for example in intra-operative nuclear imaging. The infrared tracking system commonly used for this purpose is outside-in and often suffers from line of sight issues. To alleviate these, we present the combination of an inside-out tracking technique with a hand-held mini gamma camera and an image reconstruction pipeline to provide 3D SPECT-like images in a compact flexible setup suitable for interventions. As a proof-of-concept we show first results on phantoms mimicking common nuclear medicine procedures, sentinel lymph node biopsy in thyroid and breast cancer. ...
