Read the full statement (559 words)
The SC2000 ultrasound imaging system is intended for the following applications: Cardiac, Neo-natal and Fetal Cardiac,
Pediatric, Transesophageal, Adult Cephalic, Peripheral Vessel, Abdominal, Intraoperative Abdominal, Musculo-skeletal
Conventional, and Musculo-skeletal Superficial applications. The system also provides the ability to measure anatomical
structures and calculation packages that provide information to the clinician that may be used adjunctively with other
medical data obtained by a physician for clinical diagnosis purposes. The typical examinations performed using the
SC2000 Ultrasound System are:
Cardiac Imaging Applications and Analysis
The system transmits ultrasound energy into adult, pediatric, neonatal, and fetal cardiac patients creating 2D (B), 3D, M-
Mode (M), Color Doppler (CD), Color Power Doppler (CPD), Pulsed Wave (PW) Doppler, and Continuous Wave
Doppler (CWD) to obtain images and blood flow velocity of the heart, cardiac valves, great vessels, and surrounding
anatomical structures to evaluate the presence or absence of pathology. The system may be used to acquire patient
electrocardiogram for synchronizing the diastolic and systolic capture of ultrasound images.
The system also supports catheters which are intended for intra-cardiac and intraluminal visualization of cardiac and great
vessel anatomy and physiology as well as visualization of other devices in the heart of adult and pediatric patients.
The system has Cardiac Measurements and Calculation Packages that provide information that may be used adjunctively
with other medical data obtained by a physician for clinical diagnosis purposes.
Vascular Imaging Applications and Analysis
The system transmits ultrasound energy into various parts of the body of adult patients creating 2D (B), Color Doppler
(CD), Color Power Doppler (CPD), Pulsed Wave Doppler (PWD), and Continuous Wave Doppler (CWD) to obtain
images and blood flow velocity of the carotid arteries or juggler veins in the neck; superficial and deep veins and arteries
in the arms and legs and abdomen; and surrounding anatomical structures to evaluate the presence or absence of
pathology. The system may be used to acquire patient electrocardiogram for synchronizing the diastolic and systolic
capture of ultrasound images.
The system has Vascular Measurements and Calculation Packages that provide information that may be used adjunctively
with other medical data obtained by a physician for clinical diagnosis purposes.
Superficial Imaging Applications
The system transmits ultrasound energy into various parts of the body of adult patients creating 2D (B), Color Doppler
(CD), Color Power Doppler (CPD), Pulsed Wave Doppler (PWD), and Continuous Wave Doppler (CWD) to obtain
images and blood flow velocity of conventional or superficial musculoskeletal structures and surrounding anatomical
structures to evaluate the presence or absence of pathology. The system may be used to acquire patient
electrocardiogram for synchronizing the diastolic and systolic capture of ultrasound images.
Intraoperative Imaging Applications
The system transmits ultrasound energy into various parts of the body of adult patients creating 2D (B), Color Doppler
(CD), Color Power Doppler (CPD), and Pulsed Wave Doppler (PWD) to obtain images and blood flow velocity that
provide guidance during intraoperative procedures.
Transcranial Imaging Applications
The system transmits ultrasound energy into the cranium of adult patients creating 2D (B), Color Doppler (CD), Color
Power Doppler (CPD), Pulsed Wave Doppler (PWD), and Continuous Wave Doppler (CWD) to obtain images and blood
flow velocity of the brain and surrounding anatomical structures to evaluate the presence or absence of pathology.
The system provides Measurement Packages that provide information that may be used adjunctively with other medical
data obtained by a physician for clinical diagnosis purposes.
