Yeah the focus would be on inventing non-radiation means of scanning, e g further developing Ultrasound Elastography (vibrations) or Diffuse Optical Tomography (near-infrared light). So there's the concept of a thingamajig, a plot device that moves things forward. Focusing on a narrow area gives opportunity for specificity hacks that can then unlock further pivot opportunities. You know start specific and go wider once something works
You want an ultra-low field MRI.
But that'll still be expensive to develop, slow and still potentially lethal if done sufficiently wrong
