Let B be a unital $C^{*}$-algebra, $B^{#}$ the dual space of B, and X the Hilbert B-module with a B-valued inner product <,> [6]. We define the norm ∥center dot∥x on X by ∥x∥$_{x}$ =∥<x,x>∥$^{1}$2/. Then for any bounded linear operator T on X, the B-spatial numerical range $W_{B}$(T) is defined by $W_{B}$(T)={f(<Tx, x>) : x.mem.X, f.mem. $B^TEX>X>X>>X>
