## Indications for use
Esaote's Model 6440 is intended to perform diagnostic general ultrasound studies including: Fetal, Abdominal, Intraoperative (Abdominal), Pediatric, Small organs, Neonatal, Neonatal Cephalic, Adult Cephalic, Transrectal, Transvaginal, Musculoskeletal (Conventional), Musculoskeletal (Superficial), Urological, Cardiovascular Adult, Cardiovascular Pediatric, Transoesophageal (cardiac), Peripheral Vessel. The 6440 system provides imaging for guidance of biopsy and imaging to assist in the placement of needles and catheters in vascular or other anatomical structures as well as peripheral nerve blocks in Musculoskeletal applications. The Virtual Navigator software option for Esaote model 6440 is intended to support a radiological clinical ultrasound examination (first modality) and follow percutaneous procedures or surgical operations providing additional image information from a second imaging modality (CT, MR, US, and PET). The second modality provides additional security in assessing the morphology of the real time ultrasound image. Virtual Navigator can be used in the following applications: Abdominal, Gynecological, Musculoskeletal, Obstetrics, Pediatric, Urologic, Small Organs, Intraoperative (Abdominal), Intraoperative (Neurological), Peripheral Vascular and Transcranial for radiological examinations only. The second modality image is not intended to be used as a standalone diagnostic image since it represents information of a patient that could not be congruent with the current (actual) patient position and shall, therefore, always be seen as an additional source of information. The Virtual Navigator tracking system is contraindicated for patients, operators, personnel and other people who use an electronic life support device (such as a cardiac pacemaker or defibrillator).
