“…For example, the Philips CX50 [34] scanner has a mode for 3D Trans-Esophageal Echocardiography (TEE), which is considered as an invasive examination that needs not only the presence of a sonographer but also a physician, leveraging a matrix probe of 2500 elements, but analog pre-BF is exploited to compress this data onto only 100 receive channels [35]. Cephasonics provides the first US system supporting up to 4096 channels, called cQuest Griffin [36], [37], by stacking 64 × 64-channel cQEngine modules. A 1024-channel cQuest Griffin consists of 16 cQEngine modules, consumes 640 W power, and has a size of 30 cm × 68 cm × 48 cm.…”

Ultrasound imaging is a ubiquitous diagnostic technique, but does not fit the requirements of the telemedicine approach, because it relies on the real-time manipulation and image recognition skills of a trained expert, called sonographer. Sonographers are only available in hospitals and clinics, negating or at least delaying access to ultrasound scans in many locales-rural areas, developing countries-as well as in medical rescue operations. Telesonography would require an advanced imager that supports three-dimensional (3-D) acquisition; this would allow untrained operators to acquire broad scans and upload them remotely for diagnosis. Such advanced imagers do exist, but do not meet several other requirements for telesonography, such as being portable, inexpensive, and sufficiently low power to enable battery operation. In this work, we present our prototype of the first portable 3-D digital ultrasound back-end system. The prototype is implemented in a single midrange Xilinx field programmable gate array (FPGA), for an estimated power consumption of 5 W. The device supports up to 1024 input channels, which is state of the art and could be scaled further, and supports multiple image reconstruction modes. We evaluate the resource utilization of the FPGA and provide various quality metrics to ascertain the output image quality.

“…Semi-compact systems like the Philips CX50 [5] can support full 3D Trans-Esophageal Echocardiography (TEE) imaging with a 2500-element matrix probe, but this is possible because analog pre-BF is used to reduce the channel count to just 100, at a major image quality cost. Cephasonics provides the first US system supporting up to 4096 channels, called cQuest Griffin [6], [7], by stacking 64 × 64-channel cQEngine modules. A 1024-channel cQuest Griffin consists of 16 cQEngine modules, consumes 640 W power, and has a size of 30cm × 68cm × 48cm.…”

Volumetric ultrasound (US) is a very promising development of medical US imaging. An under-exploited advantage of volumetric US is the mitigation of the strict probe positioning constrains necessary to acquire 2D scans, potentially allowing the decoupling of US image acquisition and diagnosis. However, today's 3D US systems are large and beset by high power and cost requirements, making them only available in well-equipped hospitals. In this study, we propose the first telesonography-capable medical imaging system that supports up to 1024 channels, on par with the state of the art. As a first embodiment, we have implemented our design in a single development FPGA board of 26.7cm×14cm×0.16cm, with an estimated power consumption of 6.1 W. Moreover, we have equipped our platform with an automatic positioning module to help any operator defining the scan location, hence allowing for better remote diagnosis. Our design supports two types of data inputs: real-time via an optical connection and offline over Ethernet. The reconstructed images can be visualized on an HDMI screen. The estimated cost of the proposed prototype materials is less than 4000e.
