“…Definitely, fast electronic scans of the volumes of interest need to be based on 2-D matrix arrays [10]- [14]. Unfortunately, 2-D arrays involve higher numbers (up to thousands) of transducer elements, which makes challenging the electrical interconnections, the signal routing, and the channel count of the companion open scanner.…”

Ultrasound open platforms are programmable and flexible tools for the development and test of novel methods. In most cases, they embed the electronics for the independent control of (maximum) 256 probe elements. However, a higher number of channels is needed for the control of 2-D array probes. This paper presents a system architecture that, through the hardware and software synchronization of multiple ULA-OP 256 scanners, may implement advanced open platforms with an arbitrary number of channels. The proposed solution needs a single personal computer, maintains real-time features, and preserves portability.A prototype demonstrator, composed of two ULA-OP 256 scanners connected to 512 elements of a matrix array, was implemented and tested according to different channel configurations. Experiments performed under MATLAB control confirmed that by doubling the number of elements (from 256 to 512) the signal-to-noise and contrast ratios improve by 9 dB and 3 dB, respectively. Furthermore, as a full 512-channel scanner, the demonstrator can produce real-time B-mode images at 18 Hz, high enough for probe positioning during acquisitions.Also, the demonstrator permitted the implementation of a new high frame rate, bi-plane, triplex modality. All probe elements are excited to simultaneously produce two planar, perpendicular diverging waves. Each scanner independently processes the echoes received by the 256 connected elements to beamform 1300 frames per second. For each insonified plane, good quality morphological (B-mode), qualitative (color flow-), and quantitative (spectral-) Doppler images are finally shown in real-time by a dedicated interface.

Medical imaging using different modalities has many problems. The main ones are low informativeness, various distortion noises, and a large amount of information. Fusion, denoising, and visual data compression are used to solve them in practice. Discrete wavelet transform is one way to implement various fusion, denoising, and compression methods for 2D and 3D medical image processing. Medical imaging systems produce increasingly accurate images with scanning technology and digital devices development. These images have improved quality using both higher spatial resolutions and color bit-depth. Processing a large volume of medical imaging data requires considerable resources and processing time. Modern wavelet-based devices for medical image processing do not meet the current performance demand. Hardware accelerators are being designed to solve this problem. This paper proposes new (fieldprogrammable gate array) FPGA accelerators using wavelet processing (WP) with scaled filter coefficients (SFC) and parallel computing in residue number system (RNS) to improve the performance of high-quality 3D medical image WP systems. The computational complexity is reduced using the developed WP method with SFC and the proposed wavelet filter coefficients scaling algorithm. Parallel computing is organized in RNS using moduli sets of a particular type. Hardware implementation of 3D medical image WP using the proposed FPGA accelerators increases device performance by 2.89-3.59 times, increasing the hardware resources by 1.18-3.29 times compared to state-of-the-art solutions. The device performance improvement is achieved while maintaining high-quality 3D medical image processing in peak signal-to-noise ratio terms.INDEX TERMS Medical image processing, discrete wavelet transform, scaled filter coefficients, residue number system, high-performance computing, hardware accelerator, field-programmable gate arrays.

Introduction. Ultrasonography (US) is one of the most wide-spread methods of diagnostic because this examination is simple and non-invasive. But it has several limitations such as non-reproducibility, operator-dependance and mixing of data obtaining (manual US examination) and data analyzing. Use of robotic systems for sonography is a perspective technological method which can potentially solve these limitations. Automated ultrasound breast scanning is one of the prime examples of robotic systems’ application. The aim of our article is to review solutions for ultrasonography robotization. Materials and methods. The research was conducted on Pubmed database. Results. In this article we present examples of different types of robots and robotic systems for ultrasound examination with description of their features and applications. Here we present our analysis of results that were obtained during research, robots’ classifications, fields of use and perspectives of application. Conclusion. Use of robots for ultrasound examination is perspective for decrease of sonographers’ burden, separation of data obtaining and data analyzing. It also provides changing of the workflow of ultrasound examinations making them more effective and less operator-dependent.
