Abstract
A radiation detector assembly is provided that includes a plurality of multi-detector arms (e.g., between 2 and 5), and plural detector head units disposed in each multi-detector arm. Each of the multi-detector arms defines a cavity therein. At least two detector head units are disposed within the cavity of each multi-detector arm. Each detector head unit includes an absorption member and associated processing circuitry, with the processing circuitry configured to generate electronic signals responsive to radiation received by the absorption member. Each detector head unit is configured to pivot along a sweep direction.
Claims20
A radiation detector assembly comprising:
- a multi-detector arm having a base and an arm housing that extends radially from within the base, the arm housing defining a cavity therein, the arm housing configured to translate linearly towards and away from a patient;
- between 2 and 5 detector head units disposed within the cavity of the multi-detector arm, each detector head unit comprising an absorption member and associated processing circuitry, the processing circuitry configured to generate electronic signals responsive to radiation received by the absorption member, wherein each detector head unit is configured to pivot along a sweep direction.
A radiation detection system comprising:
- a gantry defining a bore, the gantry comprising a stator and a rotor, the rotor configured to rotate relative to the stator;
- plural multi-detector arms radially disposed about the bore and mounted to the rotor, each multi-detector arm defining a cavity therein, each multi-detector arm having a distal portion and a base portion, the base portion mounted to the rotor, the distal portion extendable from the base portion;
- and
- plural detector head units disposed within each of the plural multi-detector arms, each detector head unit disposed in the cavity in the distal portion of the corresponding multi-detector arm, each detector head unit comprising an absorption member and associated processing circuitry, the processing circuitry configured to generate electronic signals responsive to radiation received by the absorption member, wherein each detector head unit is configured to pivot along a sweep direction.
A method including:
- providing plural multi-detector arms, each multi-detector arm defining a cavity therein, each multi-detector arm having a distal portion and a base portion, the distal portion extendable from the base portion;
- disposing plural detector head units in the cavity in the distal portion within each of the plural multi-detector arms, each detector head unit comprising an absorption member and associated processing circuitry, the processing circuitry configured to generate electronic signals responsive to radiation received by the absorption member, wherein each detector head unit is configured to pivot along a sweep direction;
- and
- mounting the base portion of each of the plural multi-detector arms to a rotor of a gantry about a bore defined by the gantry, the gantry comprising a stator, the rotor configured to rotate relative to the stator.
