The system is a general-purpose ultrasonic imaging instrument intended for use by a qualified physician for ultrasound evaluation/clinical analysis etc. It can be used in non-intrusive applications, including Abdomen, Cardiology, Gynecology, Obstetric, Breast, Thyroid, Musculoskeletal, Vascular (Carotid, Venous, Arterial), Nerve, Renal, and Urology. The clinical environments where the system can be used include clinics, hospitals, and clinical point of care for diagnosis of patients.
The system is intended to be installed, used, and operated only in accordance with the safety procedures and operating instructions given in the system user information, and only for the purposes for which it was designed. The system should only be operated by someone who has received proper training in the use and operation of an ultrasound system. This system produces images derived from sound echoes; those images must be interpreted by a qualified medical professional. This system in no way interprets these images or provides a medical diagnosis of the patient being examined.
