The imaging results of the semiconductor-based detectors are much better than the conventional detectors. The reason is that these semiconductor-based detectors are smaller and thinner in size and could be easily adjusted and arranged than others. This advancement in technology renders higher spatial resolution and images with less noise and without irrelevant information. This device also carries depth of interaction (DOI) which is a detecting system. The advantage of this system is that it reduces possible errors at the periphery of the examining body area.
Scientists made a research on the physical functioning capacity of the scanner. This scanner has been used in the treatment of the patients suffering from epilepsy and nasopharyngeal cancer. The clinical significance of this device has also been examined in the bodies of these patients. The research findings show that PET scanner can be used for clinical use; it is feasible for clinical use. The device is result oriented and provides higher spatial resolution and quantitative imaging which is essentially required in nuclear medicine. This device is currently being installed in Hokkaido University Hospital. The staff from the Department of Nuclear Medicine a Hokkaido University in Sapporo, Japan is present there helping to operate this device.
