In multispectral imaging systems, correction for lens distortion is required to allow pixel by pixel fusion techniques to be applied. While correction of optical aberration can be extended to higher order terms, for many systems, a first order correction is sufficient to achieve desired results. In producing a multispectral imaging system in production quantities, the process of producing the corrections...
Focused high intensity ultrasound can be used, under accurately controlled dosage conditions, to produce either temporary or permanent changes in practically any desired brain structure. Volumes of tissue smaller than one tenth of a cubic millimeter can be affected in deep brain structures of experimental animals (cats and monkeys), and regions as large as desired can be changed by moving the focal...
