fa.functional analysis - Direct integrals and fields of operators

Suppose we have a measure space (X,mu) and a measurable field of Hilbert spaces Hx on it. We can form the direct integral calH=intHxdmu, which is a Hilbert space.



Suppose now that I have a bounded operator T on calH, about which I know that it is decomposable.



Do you know of any kind of a "formula" which will "compute" a measurable field of operators Tx, such that intTx=T?
