Image of FIG. 1.
FIG. 1.

(a) A 4 × 4 matrix of 3 × 3 × 20 mm3 LYSO crystals and a 4 × 4 array GAPD used to construct PET detector module and (b) the PET detector module and preamplifier connected using a 300 cm long flexible flat cable.

Image of FIG. 2.
FIG. 2.

(a) Signal processing scheme and (b) photograph of the fabricated 64:1 position decoder circuit (PDC) and (c) the data acquisition (DAQ) module used for digital signal processing. The outputs of the 32:1 PDC with a slower trigger signal was held by a trigger signal transmitted from the other 32:1 PDC with a faster trigger signal, and then an analog pulse, channel address, and PDC board ID of the interacted (faster trigger signal) channel were transferred from the PDC to the DAQ module. The DAQ module consisted of 8-channel free-running ADC, digital I/O port, FPGA, and 2GB SDRAM.

FIG. 3.

(a) The prototype brain PET consisting of 72 detector modules arranged in a ring 330 mm in diameter and (b) signal processing architecture of the brain PET system consisting of PET detector modules, analog and digital electronics, and a host PC.

Image of FIG. 4.
FIG. 4.

(a) Energy and (b) timing spectra of one detector channel acquired with a 22Na point source.

Image of FIG. 5.
FIG. 5.

(a) Sensitivity profile as a function of axial position and (b) radial and tangential spatial resolutions of the brain PET as a function of the radial distance from the center of the scanner FOV.

Image of FIG. 6.
FIG. 6.

Tomographic images of (a) hot-rod and (b) 3D Hoffman brain phantoms acquired using the prototype PET.
