Shearlet-Based Feature Extraction for the Detection and Classification of Age-Related Macular Degeneration in Spectral Domain Optical Coherence Tomography Images
Age-related macular degeneration (AMD) is an eye disease that usually affects central vision in people older than 50 years owing to accumulation of fluid in the macular region of the retina. Optical coherence tomography (OCT) is an imaging modality that is being widely used nowadays for the detection of abnormalities in the eye. In this work, a shearlet transform–based method is proposed for automated detection of AMD. The 2-dimensional horizontal slices of spectral domain OCT imaging data are used as input images. Images are first converted to gray scale and denoised using bilateral filter. Denoised images are decompose...

Kinematic Parameters for Changing From Sitting to Standing Position and Gait in Poststroke Hemiparetic Patients
Hemiparetic individuals present changes that negatively affect the functional activities. The purpose of this article is to identify the kinematic parameters in poststroke hemiplegic patients for the duration of changing from the sitting to standing position and then to walking. Sociodemographic and clinical data were collected on the severity of stroke by using the National Institutes of Health Stroke Scale; functional mobility, by the Timed Up and Go test; and the kinematic parameters of changing from the sitting to standing position and then walking by means of the free Computation Vision Mobility software program. Ther...

Wavelet Decomposition–Based Speckle Reduction Method for Ultrasound Images by Using Speckle-Reducing Anisotropic Diffusion and Hybrid Median
Ultrasound imaging is considered as a common facility of imaging techniques used in medical field because of its benefits, but the quality of ultrasound image is affected and degraded by the type of noise generated by the backscattered signals that interfere with each other and introduce a random interference pattern. This pattern is called speckle. In this article, we develop a new denoising method by introducing a speckle-reducing anisotropic diffusion filter into 4 sub-band images gained by using 2-dimensional wavelet decomposition. Moreover, according to frequency content on each sup band, we use hybrid median filter t...

A Study on the Performance and Safety Test of Infant Incubator Devices
Nowadays, most neonatal or newborn babies are put in infant incubators to overcome distress during the postnatal care. These incubators can be defined as an optimal cabin environment with electronic equipment that enables premature babies with health problems to be able to continue their vital functions and grow. Despite the support of incubators, many newborn deaths are reported within the neonatal period. Similar to any other electromedical equipment, an infant incubator must be calibrated periodically because its malfunction may cause serious damage to the newborn's health or even lead to the newborn's death. So, the re...

Thyroid Nodule Classification Using Steerable Pyramid–Based Features From Ultrasound Images
This article proposes a feature extraction method by integrating steerable pyramid decomposition and cooccurrence matrix features for the characterization of the thyroid nodule. Steerable pyramid decomposition is carried out both in time domain and frequency domain. Textural features are obtained from the pyramid at different levels and with different filters. ReliefF method is used for feature selection. Support vector machine is used to classify the thyroid nodule as benign or malignant, and its performance is evaluated using accuracy, sensitivity, specificity, positive predictive value, negative predictive value, false ...

A Method of Facilitating Mobility in Children Undergoing Halo Skeletal Traction
The earliest documented use of skeletal traction devices was detailed by Hippocrates. From the Middle Ages through to the evolution of modern medicine, patients undergoing skeletal traction were confined to bed. Early to mid-1900s studies document the use of a halo to apply skeletal traction to manage spinal deformities. Adapted wheelchairs for halo traction were developed in the mid-1900s. Our halo traction program team modified wheelchairs and walkers to provide out-of-bed mobility. Optimization of patient independence during mobility in halo traction and the staff’s ability to manage increasing amounts of halo tractio...
