A positron emission tomography (PET) scanner may include a plurality of gamma radiation detector modules arranged to form a detector ring. Each detector module may include an array of elongated scintillation crystals. With respect to the detector ring, each elongated scintillation crystal includes a proximal end-face, two axially oriented lateral faces, two transaxially oriented lateral faces, and a distal end-face radially oriented into the detector ring to receive a gamma photon. An array of photosensors is positioned along a first of the axially oriented lateral faces of each elongated scintillation crystal to detect scintillation photons. A reflective material is positioned on the proximal end-face, the distal end-face, the transaxially oriented lateral faces, and a second of the axially oriented lateral faces of each elongated scintillation crystal to internally reflect scintillation photons. In various embodiments, a dual-channel processing circuit provides distinct timing and energy signals from the photosensors.

Lateral crystal photodiode readouts and switched diode networks for processing nuclear events

A positron emission tomography (PET) scanner includes a plurality of gamma radiation detector modules arranged to form a detector ring. Each detector module includes an array of scintillator detectors. Each scintillator detector comprises a monolithic scintillation crystal and a plurality of photodetector arrays, such as silicon photomultipliers (SiPMs). A photodetector array is positioned on at least two nonparallel faces of each scintillation crystal. In some examples, a photodetector array is positioned on each of three orthogonal faces of each scintillation crystal.

Scintillator detectors and methods for positron emission tomography

A superconductor device includes a low-dimensional material with a critical temperature higher than a critical temperature corresponding to a bulk form of the low-dimensional material. The low-dimensional material can include shape and structural modifications of a low-dimensional material. The superconductor device can include various conformational arrangements of the low-dimensional material such as nanoribbons, nanotubes, or helices. The superconductor device can include functional groups, such as hydrogen, attached to the low-dimensional material. The superconductor device can include metallic clusters located in proximity to the low-dimensional material. The superconductor device can include a low-dimensional material which is a monolayer, bilayer or multilayer.

High temperature superconducting structures

A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.
