TL;DR: A new generation PACS (Picture Archiving and Communication System) based on artificial intelligent visualization that realizes the man-machine interaction in a personalized, fast, comprehensive, quantitative and easy-to-understand way is proposed.
Abstract: This paper proposed a new generation PACS (Picture Archiving and Communication System) based on artificial intelligent visualization. It is developed from our GRIDPACS (patent number: US8805890), which combined with IHE XDS-I profile, to implement images communication, storage and display. It also uses 3D anatomical visualization model to extract multi-source data from PACS/RIS/HIS/EMR, to express patient disease location, size and severity, which was introduced as Visual Patent (VP) at previous SPIE Medical Imaging (SPIE MI 2018). It can integrate the training model of AI Imaging Diagnosis, to mark the focus and display the disease trends. The system not only has the original PACS functions, but also realizes the man-machine interaction (images and electronic medical record information between radiologist and patient) in a personalized, fast, comprehensive, quantitative and easy-to-understand way. It can be used in various medical institutions, image diagnostic centers, and imaging cloud, to support the healthy development of imaging technology in China.

Abstract: The invention discloses a quick phased array ultrasonic whole-focusing imaging technology, which includes steps of: separating a collected full-matrix data A*NRX*NTX into N two-dimensional sub-matrixdata An*NRX; performing virtual focusing to all sub-matrix data by means of algorithm based on two-dimensional forward/inverse Fourier transform; performing circulation calculation to acquire the two-dimensional focusing images of the first to Nth sub-matrixes; finally fusing the two-dimensional focusing images of all sub-matrixes to form the whole-focusing image. The method is expected to solve aproblem that a phased array ultrasonic fault detector cannot achieve real-time whole-focusing imaging, can quickly and effectively achieve high-precise quantization, positioning and qualification tointernal defects of materials, and has great promotion and application prospect.

01 May 2018TL;DR: A radar coincidence imaging method based on pseudoinverse algorithm and iterative operation is proposed to reconstruct images of targets in a noisy environment and can be used for both continuous targets and discrete targets.
Abstract: Microwave coincidence imaging (RCI) is a novel imaging technology motivated by classical coincidence imaging which has been realized in optical systems. RCI can obtain focused high resolution images of targets and overcome the shortages of conventional radar imaging technology which is highly dependent on time delay and Doppler analysis. In this paper, a radar coincidence imaging method based on pseudoinverse algorithm and iterative operation is proposed to reconstruct images of targets in a noisy environment. Such method is easy to achieve and can be used for both continuous targets and discrete targets. Furthermore, the time-delay compensation is considered which can enhance the image quality.
