Local-privacy-preserving-based and partition-based batch transmission of sectional medical image sequences in recourse-constraint mobile telemedicine systems

Abstract

As sectional medical image(SMI) sequence(e.g., computed tomography(CT) and magnetic resonance imaging(MRI)) usually consists of a several neighboring and visually similar medical images with temporal information. In the state-of- the-art SMI transmission methods, multiple neighboring SMIs are usually transmitted one by one which is very inefficient. The paper proposes an effective and efficient local-privacy-preserving-based and partition-based batch transmission scheme for the SMI sequences called the BTSI method via analyzing the visual content of the neighboring SMIs in the sequence based on the characteristics of a recourse-constraint mobile telemedicine system(MTS) and the SMIs. Three enabling techniques, i.e., 1) local privacy preserving(LPP) scheme, 2) sequence partition scheme, 3) partition-based RIB replicas selection are devised to better facilitate the BTSI processing. To the best of our knowledge, this is the first study on the sectional medical image sequence transmission from the perspective of image batching. The experimental results show that our approach is more efficient than the state-of-the-art methods, significantly minimizing the response time by decreasing the network communication cost while improving the transmission throughput.
