Mini-PET℠

Smaller is Better

World’s smallest PET scanner can retrofit almost any small animal MRI

The Mini-PET is a highly compact Positron Emission Tomography (PET) scanner that is so small and portable that it can be operated on the top of a lab bench and is mobile enough to be moved from station to station within the laboratory. It can also operate inside of a Magnetic Resonance Imaging (MRI) scanner without distorting the MRI image. It can be retrofitted into existing MRI instruments..

Why PET/MRI?

• Simultaneous PET/MRI can provide a valuable, high-resolution alternative to PET/CT, offering excellent soft-tissue contrast and anatomical detail with a reduced radiation load
• Mini-PET will allow the simultaneous acquisition of both high-resolution anatomical data (MRI) and in vivo quantitative physiological data (PET)
• The ability to acquire both of these data sets simultaneously can provide perfect co-registration of the two images, an increasingly important factor in the diagnosis of disease
• PET/MRI may eventually supplant PET/CT as the modality of choice in many clinical and pre-clinical care paths

Mini-PET in Focus: Specifications

The Mini-PET’s blocks are mounted on a multi-layer combined flexible/rigid printed circuit configured as a ring and contained within an annular enclosure. The device can be configured to comprise two rings, doubling the total number of detector elements with a corresponding increase in the axial field of view.

The Model M12 Detector ring is comprised of 12 detector blocks arranged at a common radius The Model M24 Detector ring is comprised of 24 detector blocks arranged at a common radius.

.

Each detector consists of:

• 32 pieces LYSO scintillator (2.3 mm x 2.3mm x 8mm each in 48 array)
• One 32-element Avalanche Photo Diode array directly coupled to individual scintillators
• One 32 channel ASIC chip for signal conversion

Dimensions:

• Model M12:Inner diameter 44 mm, Outer diameter 82mm, axial length 25mm (Double ring 50mm)
• Model M24:Inner diameter 85mm, Outer diameter 155mm, axial length 26 mm (Double ring 50mm)

Applications

The cost-efficient and adaptable Mini-PET will be invaluable in the fields of pharmaceutical development and infectious disease research.
