Abstract
This paper presents a real-time duplex synthetic
aperture imaging system, implemented on a commercially available
tablet. This includes real-time wireless reception of ultrasound
signals and GPU processing for B-mode and Color Flow
Imaging (CFM). The objective of the work is to investigate
the implementation complexity and processing demands. The
image processing is performed using the principle of Synthetic
Aperture Sequential Beamforming (SASB) and the flow estimator
is implemented using the cross-correlation estimator. Results are
evaluated using a HTC Nexus 9 tablet and a BK Medical BK3000
ultrasound scanner emulating a wireless probe. The duplex
imaging setup consists of interleaved B-mode and CFM frames.
The required data throughput for real-time imaging is 36.1 MB/s.
The measured data throughput peaked at 39.562 MB/s, covering
the requirement for real-time data transfer and overhead in the
TCP/IP protocol. Benchmarking of real-time imaging showed
a total processing time of 25.7 ms (39 frames/s) which is less
than the acquisition time (29.4 ms). In conclusion, the proposed
implementation demonstrates that both B-mode and CFM can
be executed in-time for real-time ultrasound imaging and that
the required bandwidth between the probe and processing unit
is within the current Wi-Fi standards.
