A pallet () for use with a gamma camera includes a rigid sheet () having a thickness (d) of less than six millimeters and a strength-enhancing curvature transverse to an axial direction (DA). At least a portion of an edge () of the rigid sheet has a bevel (B) with a length (x) along the sheet of at least about ten millimeters and a height (y) of at least about four-fifths of the sheet thickness. A protective covering () is disposed over the beveled edge. In a nuclear imaging method, a subject is disposed on the rigid sheet and a radiological image is acquired of at least a portion of the subject disposed on the sheet with at least one radiation detector head () positioned underneath or at an oblique angle below the subject. The bevel is effective to reduce or blur an edge artifact in the acquired image.

Chamfered pallet for nuclear medicine

A gamma camera () includes at least one radiation detector head (). At least one such radiation detector head () includes a plurality of capacitive elements () disposed over at least a radiation sensitive portion () of the radiation detector head. A proximity sensor monitor () is coupled with the plurality of capacitive elements to detect proximity of a subject to the radiation detector head based on a measured electrical characteristic of the capacitive elements. A collision sensor monitor () is coupled with the plurality of capacitive elements to detect conductive electric current flowing between spaced apart parallel conductive plates () of the capacitive element responsive to mechanical deformation of the spacing between the plates.

Detector head proximity sensing and collision avoidance apparatuses and methods

In an imaging method, mark positions are defined for one or more detector heads () at one or more marked angular orientations (&#x3b8;, &#x3b8;). The mark positions for at least one marked angular orientation (&#x3b8;) include a tangential offset of at least one detector head. Imaging data are acquired using the one or more detector heads following a conformal trajectory passing through the defined mark positions. The acquired imaging data are reconstructed into a reconstructed image.

Method and apparatus for human brain imaging using a nuclear medicine camera

An attitude control system uses a first order partial derivative of an error signal, representing a difference between a commanded pitch attitude and a sensed, actual pitch attitude. The first order partial derivative forms a cross product with the Earth's magnetic field to provide a X axis torque rod dipole command, which powers the torque rod in a way that causes a satellite to move toward its commanded attitude.
