From SIUI Inc.;
'Dedicated to ultrasound industry, Shantou Institute of Ultrasonic Instruments, Inc. (SIUI) has launched Apogee 3500, the Digital Color Doppler Ultrasound Imaging System.
With latest imaging technologies, high-definition image quality and excellent practical functions, the Apogee 3500 offers optimal solutions for clinical ultrasonic examination.'

'The Apogee 3500 is available with many high-density, super broadband and multi-frequency probes, such as convex, micro-convex, linear, vaginal, rectal and phased array probes, which are widely applied for different clinical diagnoses, including abdomen (liver, kidney, gall-bladder, pancreas), gynecology (uterus, ovary), obstetrics (early pregnancy, basic OB, complete OB, multi gestation, fetal echo), cardiology (adult and pediatric cardiology), small parts (thyroid, galactophore, testicles, neonate), peripheral vascular and prostate.'

From SIUI Inc.;
'SIUI's newly developed CTS-485 is a portable ultrasound system with advanced technology. With its powerful features, such as 256 grayscale, cineloop, RS232C interface and broadband high-density, multi-frequency probes, the system is designed for professional applications in cardiology, abdominal, small parts, liver, gallbladder, kidney, obstetrics, gynecology, peripheral vascular, etc. The CTS-485 has passed FDA clearance and CE Marking.'

From SIUI Inc.;
'The Apogee 800Plus ultrasound system offers a new level of high quality in image. With broad clinical application, the system delivers ease of use for cardiac and vascular exams.'
'Due to the exceptional image quality, the sensitivity of color Doppler and many other advanced features, the Apogee 800Plus offers complete diagnosis capability for your entire patient population, including abdominal, obstetrics, gynecology, adult cardiology, pediatric cardiology, peripheral vascular, small parts, breast, prostate, transcranial, etc.'

A liver sonography is a diagnostic tool to image the liver and adjoining upper abdominal organs such as the gallbladder, spleen, and pancreas. Deeper structures such as liver and pancreas are imaged at a lower frequency 1-6 MHz with lower axial and lateral resolution but greater penetration. The diagnostic capabilities in this area can be limited by gas in the bowel scattering the sound waves.
The application of microbubbles may be useful for detection of liver lesions and for lesion characterization. Some microbubbles have a liver-specific post vascular phase where they appear to be taken up by the reticuloendothelial system (RES). Dynamic contrast enhanced scans in a similar way as with CT or MRI can be used to studying the arterial, venous and tissue phase.
After a bolus injection, early vascular enhancement is seen at around 30sec in arterialized lesions (e.g., hepatocellular carcinomas (HCC), focal nodular hyperplasia (FNH)). Later enhancement is typical of hemangiomas with gradually filling towards the center. In the late phase at around 90sec, HCCs appear as defects against the liver background. Most metastases are relatively hypovascular and so do not show much enhancement and are seen as signal voids in the different phases.
Either with an intermittent imaging technique or by continuous scanning in a nondestructive, low power mode, characteristic time patterns can be used to differentiate lesions.

Cardiac ultrasound, also known as echocardiography or echocardiogram, is used to provide several different levels and types of heart testing. Cardiac ultrasound utilizes the same ultrasound principles as used for obstetric and gynecologic evaluations of pregnant women, gallbladder ultrasound and other abdominal structures.
The ultrasound is directed out of a hand held probe which can be moved to image the heart from different positions. Additionally, so that heart events can be timed, ECG leads are placed on the chest. The reflected wave is converted into an actual image of the heart and displayed in a real-time mode or M-mode ultrasound format. M-mode recordings permit measurement of cardiac dimensions and detailed analysis of complex motion patterns depending on transducer angulations. Also the time relationships with other physiological variables such as ECG, heart sounds, and pulse tracings, can be recorded simultaneously. A stress echocardiogram provides information about the cardiac performance.
Two-dimensional tomographic images of selected cardiac sections give more information than M-mode about the shape of the heart and also show the spatial relationships of its structures during the cardiac cycle (diastole to systole).
