This work introduces POIROT (Performance Observer In Receive or Transmit), a web-based tool for the assessment of receive and transmit coil designs against ultimate intrinsic signal-to-noise ratio and transmit efficiency, respectively. It enables engineers, for the first time, to evaluate how good is a design and whether there is further room for improvement before building a prototype. POIROT currently includes ultimate intrinsic data for three numerical head models at different resolutions and magnetic field strengths. POIROT could be integrated with rapid numerical EM modeling tools to develop a pipeline for coil design optimization that uses ultimate performance as the benchmark.
