TECHNICAL SPECIFICATIONS
​
We are designing a wearable PET imager that will allow relatively free movement of the head and upper body, and potentially full body movement (including walking and other ambulatory motion). The imager will take advantage of silicon photomultiplier technology (SiPM), such that detectors will be many times smaller than standard PET and can be placed close to the head. The close head placement has the additional advantage of high sensitivity such that very low doses as well as novel ligands (low concentration/low binding) can be used.

EXOSTRUCTURE SUPPORT
SEATED AMPET
BACKPACK SUPPORT
description
Support above a patient seated below. Enables freedom of head and upper body, and limited leg motion. Most robust support allows for heavy unit with best sensitivity, resolution and coverage of the AMPET models.
Support by external structure or overhead track. Enables movement of head and upper body in confines of a lab (e.g. walking and balancing). Maintains relatively high sensitivity, resolution and coverage since weight is supported.
Support built into backpack. Enables highest freedom of movements (although must be slow), allowing subject to leave laboratory environment. Weight limited to about 10 pounds and supported by patient's hips and shoulders.
Brain research, potential for clinical diagnostics.
Brain research, potential for clinical diagnostics.
Can be moved bedside or into clinic.
Can be set up in room or track system on ceiling, construction required.
Physical therapy like walking Parkinson's and stroke recovery, balance, traumatic brain injuries, social interactions.
Brain research, potential for clinical diagnostics.
Carried by participant, requires nearby injection station, such as a labspace or mobile truck/van.
"Walk in the park," natural behaviors, basic research.
