This study proposes a new progressive distributed and parallel similarity retrieval scheme for computed tomography image sequences in mobile telemedicine networks. Experimental evaluation demonstrates that the proposed method is more progressive than existing techniques and significantly reduces response time.
Computed tomography image (CTI) sequence is essentially a time-series data that typically consists of a large amount of nearby and similar CTIs. Due to the high communication and computational costs, it is difficult to perform a progressive distributed similarity retrieval of the large CTI sequence (CTIS)s, particularly in resource-constraint mobile telemedicine network (MTN)s. In this paper, we present a DPRS method-progressive distributed and parallel similarity retrieval scheme for the CTISs in the MTN. To the best of our knowledge, there is little research on the DPRS processing, especially in the MTN. Four supporting techniques (i.e., (1) PCTI-based similarity measurement, (2) lightweight privacy-preserving strategy, (3) SSL-based data distribution scheme, and (4) the UDI framework) are developed. The experimental evaluation indicates that our proposed DPRS method is more progressive than the state of the art, with a significant reduction in response time.
