摘要：

A three-dimensional projection reconstruction technique is described for imaging boron-11 distributions, with potential application to boron neutron capture therapy. The method samples a spherical volume of k space uniformly to obtain a 32 x 32 x 32 matrix with voxel size of 0.42 cm3. A signal-to-noise ratio (S/N) of 3 was obtained in 8.5 minutes in a phantom containing 75-mu-g/mL of boron in borocaptate sodium (BSH). Images were obtained in a dog after cessation of an intravenous infusion of BSH and again 30 minutes later, with a maximum boron S/N of about 12. Boron levels in the brain dropped about 6%-8% and were more diffusely distributed on the images obtained 30 minutes after BSH infusion.
