Abstract
The present invention provides a vaginal imaging device for quantifying morphological and biochemical changes in the pelvic floor muscles as well as monitoring muscular function. Specifically, the present invention provides a vaginal imaging probe comprising a single or dual tuned resonator for both nuclear magnetic resonance imaging and spectroscopy of the pelvic floor musculature.
Claims34
A vaginal imaging device, comprising:
- a single tuned or dual tuned resonator comprising a transmit/receive element for nuclear magnetic resonance imaging or nuclear magnetic resonance and spectroscopy;
- a tuning/matching network remote from said resonator;
- and
- a force transduction mechanism for monitoring a subject's contraction effort and to trigger said resonator to produce vaginal imaging and spectroscopy data.

A vaginal imaging device, comprising:
- a single tuned or dual tuned resonator for nuclear magnetic resonance imaging or nuclear magnetic resonance and spectroscopy comprising a Helmholz array;
- a tuning/matching network remote from said resonator;
- and
- an optical force transducer that generates a gating signal from an optical signal proportional to developed force, said gating signal triggering said resonator to produce vaginal imaging and spectroscopy data.
