There are already ultrasound scanners that aren't much bigger than a cell phone (Siemens makes one). The problem is that the acquisition devices for most other imaging modalities (CT or MRI, say) are much too large and complex to benefit from this concept. (The authors of this study used electrical impedance tomography.)
