Classification System for Heart Sounds Based on Random Forests
In this study, a classification method is proposed to classify normal and abnormal heart sound signals using random forests algorithm. The proposed framework was applied to a database of 100 heart sound signals which collected from the web site, firstly all the signals were processed using the wavelet technique to eliminate the noise from the signal, features were extracted from the enhanced signals and the most significant features was selected using the RFs. Finally the random forests classifier was used to perform the classification process. The system achieved 93.24% accuracy in distinguishing between normal and abnorm...

Brain Tumor Classification Using Principal Component Analysis and Artificial Neural Network
The abnormal growth of cells in the brain is known as brain tumor. A brain tumor is a kind of disease that can hit children, adults, and older adults. In this work, a proposed method for brain tumor detection and classification using MATLAB and based on magnetic resonance imaging plays an essential role in the brain-tumor disease diagnostic application that is based on manual and automatic detection. Moreover, various kinds of tumors exist so it is complicated to detect, and thus it is hard to make decisions. Correct segmentation and image enhancement give an accurate classification of brain tumor types. A probabilistic ne...

Optic Disc Segmentation Using Manual Thresholding Technique
Optic disc segmentation is a very important step in diagnosing glaucoma disease, where untreated glaucoma leads to irreversible loss of vision. Glaucoma is the second cause of blindness around the world. In this work, manual thresholding technique in optic disc segmentation is applied, evaluated, and compared with other segmentation techniques. The optic disc segmented by thresholding level 180 after vessel removal by morphological operation to improve segmentation process, and then boundary smoothed by dilating and eroding operation and border clearing; at final segmentation step, the segmented part was shaped to construc...

Electrosurgical and Electrocautery Device Failures and Best Reporting Practices
Electrosurgical units play a vital role in operating rooms today. Their failures have the potential to harm both patients and surgeons. In this article, US Food and Drug Administration (FDA) postmarket safety reports involving electrosurgical units were examined to determine the most common failure categories of these devices. Based on this analysis, mechanical failure was the most prevalent failure experienced, primarily through part detachment, failing to articulate or movement/motion issues, or improper or poor cutting. When these issues are properly reported to FDA, FDA can work with manufacturers to improve these devi...

Failure Mechanisms of Polymeric Medical Devices
Medical devices manufactured today typically require a number of different components and materials. Commonly, mass-produced devices utilize biocompatible polymers for their external surfaces. In this article, we discuss common failure mechanisms of polymers and a number of contributing factors, related to both the use and manufacturing of these devices. Reprocessing and cleaning of reusable medical devices can also contribute to their failures when incompatible substances or techniques are used. Thorough postmarket reporting of any medical device failure can allow enhancements of the device to be made and will ultimately ...

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 decom...

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...

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 tra...

Cetacaine Spray as an Ex Vivo “Plastic-on-Plastic” Lubricant for Airway Management Procedures: A New Use for Dipropylene Glycol?
In addition to being an aerosolized topical local anesthetic, Cetacaine Spray has the physical property of being an excellent medical lubricant for airway management and related procedures. This is a result of the constituent ingredient dipropylene glycol (DPG). However, because of the presence of benzocaine, this medication can cause methemoglobinemia if absorbed excessively. The authors speculate that aerosolized DPG may be useful as medical lubricant, independent of the local anesthetics contained within Cetacaine Spray. Further research into this potential application of DPG may be indicated. (Source: Journal of Clinical Engineering)

Investigating Repeat Service Calls
Service on demand (repair) is a regular part of medical equipment maintenance. Repair can be approached as a 1-time situation of finding the problem and fixing it, or it can be approached as an integral part of keeping the medical device environment in full functioning condition at managed cost. The latter requires an organized commitment to not only repair but also determine why repair was needed and what if anything could be done to reduce subsequent failures. This is particularly the case for repeat service calls over an unexpectedly short period. (Source: Journal of Clinical Engineering)
