What was discovered
Calderón asked whether the conductivity inside a body can be determined from voltage and current measurements on its surface. The problem is the mathematical basis of electrical impedance tomography.
Calderón, an Argentine trained in Buenos Aires and based in the United States, presented it at the Rio de Janeiro Seminar on Numerical Analysis (1980); the paper was reprinted in 2006.
What it led to
- Electrical impedance tomography
- Modern theory of inverse problems
- Sylvester–Uhlmann uniqueness results (1987)
