Correction to equation 96 on page 83
When n is odd, the last term in equation 96 should read
g(n alpha) = -1/(2 pi^2 sin^2 (n alpha)).
The other terms are correct.
Thanks to Conway Yee for telling us there was an error and Carl Crawford
for confirming the correction.
Correction to Table 3.2 on page 102 (3d Shepp and Logan Parameters)
The original table had two identical rows.

Correction to Iwa75 reference on page 210
At the end of the first (partial) paragraph on page 210

The correct references are either:
- B. D. Coleman, "Foundations of linear viscoelasticity,"
Rev. Mod. Phys., Vol. 9, pp. 443-450, 1981.
- D. Nahamoo and A. C. Kak, "Ultrasonic Diffraction Imaging,"
Technical Report TR-EE-82-20, School of Electrical Engineering, West
Lafayette, IN, 1982.
Thanks to M. A. Lewis (CWRU) for pointing out this error.
