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

Methods and systems for patient positioning in an imaging system are provided. A palette for an imaging system is provided that includes a base portion movably connected to the imaging system and an extender portion removably connected to the base portion. The extender portion together with the base portion supports an object to be imaged by the imaging system.

A method for calibrating a non-pixelated gamma camera is provided, wherein the method includes determining a linearity map and a uniformity map of a reference isotope; and determining a linearity map and uniformity map of another isotope. Delta maps are calculated based on the maps of the reference isotope and the maps of the other isotope. During recalibration, new maps of the reference isotope are determined, thereby enabling new maps of the other isotope to be created based on the delta maps.

Systems and methods for generating calibration maps for non-pixelated gamma detectors

Methods and systems for a patient table having a longitudinal axis for a medical imaging system are provided. The patient table includes a body including a first end, an axially-spaced second end, and a first and a second axially oriented side edges extending therebetween, the body further including at least one of an aperture extending through the body and a notch extending from at least one of the first and second axially oriented side edges, and a base configured to couple to the body using at least one of the first end and the second end.

Methods and systems for reducing radiation attenuation in imaging systems

A high resolution x-ray imaging device based on a storage phosphor layer. The storage phosphor layer is sandwiched between two arrays of electrodes. In one embodiment of the device, the arrays are orthogonal arrays of linear electrodes, one of the arrays being transparent to the phosphorescence emitted by the storage phosphor. To read a pixel of a latent image stored in the storage phosphor layer, a voltage difference is established between two crossed electrodes that exceeds the threshold voltage of the storage phosphor material. The emitted light is detected by a device such as a CCD array that has coarser resolution than the crossed electrode array: the resolution of the imaging device of the present invention is the electrode width. Preferably, the electrodes are addressed for activation by optical scanning of photoconductive strips adjacent and perpendicular to the electrodes. Also preferably, the electrodes are addressed in interleaved subsets, each with as many electrode intersections as there are pixels in the CCD array, to create subimages which are interleaved to provide a final image having a resolution finer than the resolution of the CCD array. In another embodiment of the device, one array is a single electrode and the other array includes several electrodes. A subimage of the latent image is read by establishing a voltage difference between the single electrode and one of the several electrodes that exceeds the threshold voltage. The emitted light is detected by a CCD array with the resolution of the CCD array. The several subimages are assembled to provide a final image having a resolution finer than the resolution of the CCD array.
