ATOX co-developed with National Institute for Quantum and Radiological Science and Technology the world's first Helmet-type PET. By arranging detectors in a hemispherical shape so that they are close to the patients, this device offers a high-resolution image in spite of its small number of detectors.
Seeking higher sensitivity by helmet-shape, not like conventional cylinder-shape
If a cylinder and hemisphere have the same radius and height, they have the same surface area, and therefore the number of detectors used in the device is the same, however, the radiation detection sensitivity of the hemispherical type is 1.5 times higher than that of the cylindrical type.
(Sensitivity comparison between conventional cylindrical PET and hemispherical PET)
TOF-PET with SiPM-adopted semiconductor detectors
Our detector module, containing 4.1mm-square Lutetium-based scintillator and SiPM, achieves high temporal resolution.
High quality image
ATOX and QST co-developed a new scatter correction method, and image uniformity, noise and contrast are improved by optimizing the inspection condition.

Space saving achieved by compact design
Vrain achieved space saving by implementing an optimized air-cooling mechanism between the detectors and cooling system as well as the sitting-position design.
ATOX provides various services related to nuclear power sector including radiation control and it has been one of our expertise for a long time. We support for customers who install Vrain for the first time in designing and renovating controlled areas.
