摘要: An imaging capsule, including a radiation source, a collimator that provides a collimated beam from the radiation source, a detector configured to detect particles resulting from X-ray fluorescence and/or Compton backscattering in response to the collimated beam, a motor to rotate the collimator and detector around an axle to scan a partial or full inner circumference of a user's colon with radiation, wherein the motor comprises a segmented commutator that is fed with a power signal via brush contacts; and wherein the motor provides a pulsed output signal based on mechanical switching of the segmented commutator on the brush contacts, providing an indication of the rotation angle of the motor as a function of time.

摘要: An imaging capsule including, a radiation source, a collimator that blocks the emission of radiation from the radiation source except through one or more output columns, a shutter comprising one or more openings; wherein the shutter is rotatably coupled to the collimator to enable selecting at least two states; a closed state in which the shutter blocks the emission of radiation from the radiation source, and an open state in which the shutter does not block the emission of radiation, a motor configured to rotate the collimator and select the state of the shutter, a main power source configure to power the motor, a circuit that monitors a status of the main power source and instructs the motor to place the shutter in the closed state if power in the main power source is below a threshold value.
