Abstract

A serialized probe component for an optoacoustic device has a unique identifier associated therewith and includes, in an embodiment, an operative connection between a read-write memory and the optoacoustic device. Software adapted to generate and store logs in a read-write memory is executed on the optoacoustic device and stores logs concerning utilization of the serialized probe component on the read-write memory. A method for logging operational information concerning an optoacoustic device is further disclosed.

First claim
