I won't answer your question directly but some suggestions:
a) does adding PACKAGE="ANTsR" to .Call change anything? (It should really be
there if you are using strings as names)
b) you may want to consider use the more efficient registration - either
explicit or in NAMESPACE - so in your case you could use
NAMESPACE: useDynLib(ANTsR, antsImageRead, ...)
foo.R: .Call(antsImageRead, ...)
