A Lung Sound Category Recognition Method Based on Wavelet Decomposition and BP Neural Network.

In this paper, a method of characteristic extraction and recognition on lung sounds is given. Wavelet de-noised method is adopted to reduce noise of collected lung sounds and extract wavelet characteristic coefficients of the de-noised lung sounds by wavelet decomposition. Considering the problem that lung sounds characteristic vectors are of high dimensions after wavelet decomposition and reconst...

Segmenting lung tumors on longitudinal imaging studies via a patient-specific adaptive convolutional neural network.

PURPOSE: To design a deep learning algorithm that automatically delineates lung tumors seen on weekly magnetic resonance imaging (MRI) scans acquired during radiotherapy and facilitates the analysis of geometric tumor changes.

Rapid microarray-based assay for detection of pyrazinamide resistant Mycobacterium tuberculosis.
