Ultrasound diagnostic apparatus and ultrasound probe

An ultrasound diagnostic apparatus, comprising:

• an ultrasound probe including a plurality of transducers, a first memory, and binary state generation circuitry;
• an apparatus main body to which the ultrasound probe is connected;
• a second memory included in the apparatus main body and storing list information concerning a plurality of probe identifiers respectively corresponding to a plurality of ultrasound probes;
• and
• processing circuitry included in the apparatus main body,
• wherein the first memory stores probe use history information and encrypted probe identification information, the encrypted probe identification information being encrypted based on the probe use history information by the processing circuitry;
• and
• the binary state generation circuitry is configured to generate a binary electrical state;
• and
• the processing circuitry is further configured to
• convert the binary electrical state into a probe identifier;
• read the encrypted probe identification information and the probe use history information from the first memory;
• decrypt the encrypted probe identification information based on the probe use history information;
• determine whether there is first consistency between the probe identifier and the stored list information;
• determine whether there is second consistency between the decrypted probe identification information and the stored list information;
• and
• output a predetermined warning when there is not at least one of the first consistency and the second consistency.
