摘要： A device (10) for determining the number of discrete events represented by an input signal is provided. The input signal may, for example, comprise pulses representing photons arriving at a detector. The device (10) may comprise a plurality, n, of comparator circuits (14) for reading the signal. For each comparator circuit (14) from i=1 to i=n, the i
th comparator circuit (14) has a corresponding threshold value which the amplitude of a pulse representing i discrete events will exceed, but which the amplitude of a pulse representing i-1 discrete events will not exceed. Each comparator circuit (14) is arranged to output a first value when the input signal exceeds its threshold value and a second value when the input signal is less than its threshold value. The device (10) includes a counter (16) for counting the number of outputs of the first value that have been output by the plurality of comparator circuits (14).

摘要： A radiation detector (16) having a first detector layer (24) and a second detector layer (26) encircles an examination region (14). Detectors of the first layer include scintillators (72) and light detectors (74), such as avalanche photodiodes. The detectors of the second detector layer (26) include scintillators (62) and optical detectors (64). The scintillators (72) of the first layer have a smaller cross-section than the scintillators (62) of the second layers. A group, e.g., nine, of the first layer scintillators (72) overlay each second group scintillator (62). In a CT mode, detectors of the first layer detect transmission radiation to generate a CT image with a relatively high resolution and the detectors of the second layer detect PET or SPECT radiation to generate nuclear data for reconstruction into a lower resolution emission image. Because the detectors of the first and second layers are aligned, the transmission and emission images are inherently aligned.

摘要： The vertical silicon photomultiplier according to the present invention includes a trench electrode and a PN-junction layer perpendicular to the trench electrode forms and can maximize the quantum efficiency at optical wavelengths, 200~900 nm in such a way that: it generates electric fields horizontal thereto, by applying a reverse bias voltage to between the trench electrode and the PN-junction layer, so that, although ultraviolet light does not reach the PN-junction layer but is incident on the surface, electron-hole pairs can be produced by the horizontally generated electric fields although and an avalanche breakdown can be thus generated; and it allows ultraviolet light, capable of being transmitted to a relatively deep depth, to react with the PN-junction layer.

摘要： A presente invenção diz respeito a um aparelho de leitura e método para realizar medições de tempo e energia dos eventos produzidos por um fotomultiplicadcr de silício (SiPM) acoplado a um cint ilador. A medição de sincronismo após calibração pode ser tão precisa quanto 50 ps ou inferior. A energia é medida usando uma técnica de tempo- acima-do-limiar ("time-over-threshold"), e a resolução de energia só é limitada pela estatística de cintilação. Para alcançar tão baixo consumo de 10 mW por canal são usados um amplificador com baixa impedância de entrada e conversores de tempo analógico-digital (TDCs) baseados em interpolação de tempo. O circuito de leitura pode ser desencadeado por um único fotoelectrão (p.e.) com uma relação sinal-ruído ( SNR) acima de 20 dB. O circuito de leitura referido opera com SiPMs de diversos ganhos, polaridades e dimensões de matriz. A materialização preferencial do aparelho de leitura é um circuito integrado de aplicação específica (ASIC) composto por 64 canais.
