Thorax Diseases Research Articles

Thorax disease diagnosis using deep convolutional neural network.

Computer aided diagnosis (CAD) is an important issue, which can significantly improve the efficiency of doctors. In this paper, we propose a deep convolutional neural network (CNN) based method for thorax disease diagnosis. We firstly align the images by matching the interest points between the images, and then enlarge the dataset by using Gaussian scale space theory. After that we use the enlarged dataset to train a deep CNN model and apply the obtained model for the diagnosis of new test data. Our experimental results show our method achieves very promising results.

Romanian medical exposure to ionising radiation in 2012

Medical exposure, the main source of artificial exposure, shows an increasing trend in the last years, manifested both by increasing the number of examinations with ionising radiation and by increasing the patient dose level. Annual results obtained for medical exposure to ionising radiation based on the data collected from Romanian hospitals are useful for the update of the national database and optimisation of diagnostic procedures in radiology and nuclear medicine. Medical exposure level is expressed in terms of annual collective dose and is evaluated from annual frequencies and the average effective dose per procedure for different types of radiological and nuclear medicine procedures. The Romanian hospitals reported during 2012 a number of 5,505,792 radiological examinations and 17,088 diagnostic procedures of nuclear medicine. Based on the data reported, the average effective doses and their contributions to the collective dose were evaluated. The main contributions to the collective dose of the radiological procedures are registered for CT abdomen and pelvis region, followed by thorax CT and head CT examinations. The next positions are fluoroscopic examination of the thorax and gastrointestinal disease and radiographic examination of the lumbar spine and thorax, which in spite of their low effective dose have an important contribution to the collective dose due to the large number of examinations. For nuclear medicine procedures, major contributions to collective dose are given by bone scintigraphy, followed by PET-CT and thyroid scintigraphy.

Advanced approaches to computer-aided detection of thoracic diseases on chest X-rays

The research focus of the current paper are modern algorithms for solving the problem of automatic diagnostic of thorax diseases based on X-ray images. Special attention was paid to image preprocessing, classification together with calculation of features and their comparison in terms of efficiency. Approaches mentioned in this paper are used for development of new algorithm for automatic diagnostic of medical images.

Bronchial asthma, symptomatology and therapeutic method in traditional medicine

Precice information on the treatment of bronchial asthma in Persia up to 9th and 10th century is not available. However according to some old religious books like Yasna and Vendidad, the “Haoma” had been used in the treatment of perspiration disorders and its extract had been advised by Zoraster as sacred water. There are some interesting idea about treatment of thorax diseases, which consist: Dyspnea, Bronchial asthma, Orthopnea, Emphysema, Hemoptysis, Differential diagnosis between pneumonia and pleurisy, Differential diagnosis between bleeding of thorax and lung, Diaphragmitis, Atelectasis….. Symptomas of disease: Three main symptoms of bronchial asthma have been described: 1- Special difficulty in breathing: The patient can not breath unless he turns his head backward, and his breathing is accompanied with wheezing and it is similar to that of a person who has run for a long time. Inspiration is difficult and expiration is long. 2- Presence of characteristic sputum which could be found either in trachea or in the lungs. Sputum could be expelled by coughing. In case sputum is present in the lungs there is less coughing and sputum expelling not as easy as in the former case. 3- The patient has disturbed plus. Etiology: Ancient Iranian physicians have mentioned so many factors which are helpful in existence of this disease and consist of: smoke, dust, cold or coryza, enlargement of stomach, liver, cold temperament, nervous temperament, narrownese of larynx, Trachea, bronchiolus, bronchiole and lungs. Treatment of real causes: For treatment it is necessary that the real reasons of the disease be diagnosed and the treatment depends on the cause of the bronchial asthma. Treatment of real causes, treatment children and adult, medical plants, mineral drugs and biological drugs which have been used, and side treatment will be discussed in full paper.
