Abstract
Diagnostic apparatus (20) includes an antenna 32, which is configured to direct radio frequency (RF) electromagnetic waves into a living body and to generate signals responsively to the waves that are scattered from within the body. Processing circuitry (36) is configured to process the signals so as to locate a feature in a blood vessel in the body.
