What the code means
A cardiovascular sonography technologist operates special equipment to create images and conduct tests of the cardiovascular system. They work with physicians who view the images and test results to assess and diagnose medical conditions.

Where they are
Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Who registers under this code
352 of these are people and 178 are organisations, so 34% of the code is businesses rather than clinicians. Half of them had registered by 2010, and 90 registered in the last five years, 17% of the current population.
That is close to the pace of the registry as a whole.
Where the practices are
By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider
These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
