A panel PET with window for tumor surgery guidance

With high specificity of tumor necrosis, hypoxia tissues and subclinical lesions, PET may have great potential for tumor surgery guidance. PET images in surgery will tell us how tissues change during the operation and whether the lesion has been cleared. We did research on panel PET guided therapy, and we have developed 3-dimensional reconstruction methods for panel PET systems. However we meet the requirement of a larger open space for operation, because a body covered with two enclosed panels could barely be operated in most tumor surgeries. And the weak performance of images perpendicular to panels leads to invalid guidance in some applications such as radiotherapy guidance. In order to apply the better images to guidance, we designed a panel PET with window for tumor surgery guidance, and it showed good performance of the images parallel to the panels. It is surprising that we took 12 seconds for scanning and acquired images parallel to the panels with good performance in the actual system experiment.
