introduction: lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. lymphoscintigraphy usually encompasses early or delayed static images. however, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. the aim of this study was to assess the role of early dynami...

This paper describes a node-pruning method for an acoustic model based on deep neural networks (DNNs). Node pruning is a promising method to reduce the memory usage and computational cost of DNNs. A score function is defined to measure the importance of each node, and less important nodes are pruned. The entropy of the activity of each node has been used as a score function to find nodes with o...

  Introduction: Many radiotracers have been used for sentinel node mapping with acceptable results. The main difference between these radiotracers is the particle size. In the current study, we reported defective labeling of Tc-99m antimony sulfide colloid which resulted in large particle size. Methods: Tc-99m-Antimony sulfide colloid was used for axillary sentinel n...

A free space optics based ring topology that transmits full-duplex data to four different nodes in the is proposed. The link designed such do not require a local optical source transmit uplink data. wavelength division multiplexed signal composed of wavelengths each modulated by downlink baseband using differential phase shift keying transmitted towards nodes. At node, extracted and received pu...
