Claim One:
1. An apparatus for single photon emission computed tomography (SPECT) imaging, comprising: a robotic arm movable in three rotational degrees of freedom, the three rotational degrees of freedom comprise a first roll axis, a second roll axis and a third roll axis, the robotic arm including: a base end and a distal end, the distal end configured to support a plurality of SPECT imaging detectors; a first arm assembly having a first rotational mechanism coupled with a proximal end of a second arm, the first rotational mechanism configured to drive a roll-rotation movement of the second arm along the second roll axis; a head assembly configured to house the plurality of SPECT imaging detectors, the head assembly being attached to the distal end of the second arm, the head assembly including a head rotational mechanism configured to drive a roll-rotation movement of the head assembly along the third roll axis; and a base assembly having a base rotational mechanism coupled with the first arm assembly, the base rotational mechanism configured to drive a roll-rotation movement of the first arm assembly along the first roll axis; a patient support assembly movable in a linear degree of freedom; and a controller configured to cause the robotic arm to move the plurality of SPECT imaging detectors in three dimensions around a patient's body to obtain SPECT images, and cause the patient support assembly to move along the linear degree of freedom to maintain alignment of the patient's body with the plurality of SPECT imaging detectors.
