PETonCHIP: architecture of a on-chip high-resolution, fully digital positron emission tomography scanner for small Animal Imaging

Abstract: Abstract-Small animal PET systems based on a reduced number of rotating planar detectors have advantages in terms of cost/performance for high resolution imaging. The huge integration capability of current semiconductor technologies has favoured miniaturization and popularised the concept of system on a chip. Following this trend, this work attempts to integrate in a single chip the acquisition electronics and coincidence unit of a fully digital four-head PET scanner. The proof of concept is based on commercia… Show more

“…Field programmable gate array (FPGA) based systems have recently been adopted to replace conventional analog circuitry in some small animal PET systems [30]–[33]. An FPGA based digital signal processing board (VHS-ADC V4; Lyrtech, Quebec, Canada) was used in this work for data acquisition and signal processing.…”

“…Guerra et al [16] proponen diferentes algoritmos, entre los que se incluyen la interpolación lineal, DCFD, un filtro adaptado clásico (que usualmente es considerado elóptimo en la presencia de ruido aditivo) y un filtro adaptadoóptico (que está pensado para ruido de Poisson típico de detectores de partículas). En su trabajo, proporcionan detalles de la implementación hardware de los algoritmos de extracción del tiempo del pulso recibido, como parte de un PET para animales pequeños [136].…”
