1. An apparatus to receive radio frequency signals characteristic of a targeted specimen, the apparatus comprising:
- a housing designed to be inserted into a patient;
at least two radio frequency receiver coils, each of which (i) is positioned inside the housing, (ii) has an operating radio frequency, and (iii) includes;
a circuit proximal to the radio frequency receiver coil for blocking an external transmitter at its own operating radio frequency and a circuit for providing a passive block at the operating radio frequency of other ones of the radio frequency coils;
each circuit to seek only a single frequency;
wherein the radio frequency receiver coils are superimposed upon each other.

Abstract
Systems, methods and apparatus are provided through which a compact pod insertable into the rectum for Magnetic Resonance Imaging/Magnetic Resonance Spectroscopy (MRI/MRS) examination of the prostate and containing two receive coils, each connected to transmit blocking and pre-tuned trap circuitry which can be superimposed within the pod in close proximity, can, without either circuit interfering with the other, efficiently gather, for imaging and tissue analysis, radio frequency signals emanating from magnetically disturbed nuclei in prostate tissue.
