Methods and systems are provided for calibrating a nuclear medicine imaging system having more than 5 detector heads. In one embodiment, a method includes obtaining residual center of gravity determinations corresponding to each of a plurality of detector units based on point source projections acquired over a series of detector unit rotational steps, obtaining center of gravity determinations for each of the plurality of detector units based on point source projections acquired over a series of detector unit sweep angles, obtaining a fit of the center of gravity determinations for each of the plurality of detector units, and determining a sweep offset for each of the plurality of detector units based on the residual center of gravity determinations and the fit of the center of gravity determinations for each of the plurality of detector units. In this way, a sweep axis zero degree position for each of the plurality of detector units is determined.

Systems and methods for mechanically calibrating a multidetector of a nuclear medicine imaging system

Nuclear medicine (NM) multi-head imaging system includes a plurality of detector units coupled to a gantry. The detector units configured to face toward a center of the bore and including a series of first detector units and a second detector unit. The system also includes at least one processor that, when executing programmed instructions, performs the following operations. The at least one processor rotates the first detector units such that the first detector units face in a common first direction that is generally toward the bore. A working gap exists between the detector FOVs of the respective first detector units. The at least one processor rotates the second detector unit such that the second detector unit faces in a second direction that is opposite the first direction. The detector FOV of the second detector unit covers the working gap.

Systems and methods for imaging with multi-head camera

An imaging system is provided including a plurality of detector units and a controller. The plurality of detector units are distributed about a bore. The bore is configured to accept an object to be imaged, and the detector units are radially articulable within the bore. The controller is operably coupled to the plurality of detector units and configured to control the positioning of the detector units. The controller is configured to position an external group of the plurality of detector units at a predetermined intermediate position corresponding to a ring having a radius corresponding to a total number of detector units, and to position an internal group of the plurality of detector units radially inside the ring.

Systems and methods for positioning detector heads

A method of examining a patient is provided. The method includes aligning a patient table with a first examination axis, and rotating the patient table around a substantially fixed pivot axis from the first examination axis to a second examination axis using a predetermined angular velocity profile.

Apparatus for aligning an object being scanned in multi-modality systems

A multimodality imaging system including a plurality of imaging systems, and at least one rail upon which at least one of the imaging systems is slidingly mounted.
