From ALOKA Co., Ltd.;
'A Platform for Digital, Pure-Beam Imaging The high-performance, ALOKA ProSound SSD-3500 utilizes advanced ProSound technologies including:
Fully digital beam former A wide dynamic range, 12-bit A/D converter Multi beam processing.
The SSD-3500 also helps you achieve more efficient examinations. Its ergonomic, user-friendly design enables you to customize the system according to your specific application needs.'

From ALOKA Co., Ltd.;
'The ProSound SSD-4000 utilizes the most advanced acoustic technologies available today, and its multidisciplinary technology architecture enables it to offer great versatility and flexibility over a wide range of clinical applications.
With its new-generation, front-end technology including a 12-bit A/D converter, the ProSound SSD-4000 offers superior contrast resolution−especially when compared to 10-bit systems.'

From ALOKA Co., Ltd.;
'Innovative Image Quality in a Compact Size.
Featuring design concepts inherited from our higher end systems along with Aloka's latest proprietary electronic technologies, the compact SSD-900 delivers superb images.
Traditionally, portable units suffer from hardware and software limitations that affect image quality. Aloka's SSD-900 sets new standards for what's possible in a portable unit. Incorporating over 50 years of experience and unique micro-chip technologies, the SSD-900 generates incredibly high-resolution images.
The SSD-900 offers a full range of measurement functions for professional ultrasonic examination. And unlike conventional portable systems, the SSD-900 includes annotation labeling and 15-channel preset functions as standard features.
The system also use Super High Density transducers (found our high-end systems) to enhance imaging resolution. These multi-frequency transducers provide a broad range of imaging frequencies to optimize scan frequency for depth of view.'

The Doppler signal from any range gate is proportional to the number of red blood cells moving through during the periods of its read out, so the amplitude (or loudness) works as an indicator of the number of blood cell reflectors.
High Doppler amplitudes are generated by large pulsed Doppler or color Doppler imaging range gates and large vessels.
