Abstract: Brain science is currently a highly challenging research hotspot, and in vivo brain function observation in living animals is critical to its advancement. As a non-invasive functional imaging modality, positron emission tomography (PET) offers unique advantages in such applications. However, conventional animal PET imaging requires the subject to be anesthetized or restrained, resulting in a non-awake or non-free-moving state; the observed outcomes therefore do not reflect the normal state of brain function. Meanwhile, brain function is dynamically changing, and existing animal PET systems cannot simultaneously achieve satisfactory temporal resolution and image quality, making it difficult to meet the demands of dynamic brain function observation. We have developed a “Bi-Dynamic” PET instrument capable of dynamic imaging in awake and freely moving animals, enabling high-temporal-resolution and high-spatial-resolution dynamic imaging of the rat brain.
