Let T denote an operator on a Hilbert space โ€ข โ€ข , and let f i โˆž i=1 be a frame for the orthogonal complement of the kernel N T . We construct a sequence of operators n of the form n โ€ข = n i=1 โ€ข g n i f i which converges to the psuedoinverse T โ€  of T in the strong operator topology as n โ†’ โˆž. The oper
