Apparatus, systems, and methods for magnetic induction tomography imaging using a hand held device are provided. More particularly, a magnetic induction tomography imaging system can include a hand held magnetic induction tomography device having a housing and at least one sensing unit. The housing of the hand held device can have a form factor such that the location of a hand holding the housing is separated from the sensing unit when the hand held device is in operation. The hand held magnetic imaging tomography device can include one or more electrical components separated in the housing (e.g., by shielding) from the at least one sensing unit to reduce electromagnetic interference between the at least one sensing unit and the one or more electrical components. A positioning system involving components included internally and/or externally to the hand held device can be used to determine position data for the hand held device.
