RESTORATION OF MAMMOGRAPHIC IMAGES IN THE PRESENCE OF SIGNAL-DEPENDENT NOISE Previous efforts in improvement of appearance of digitized mammograms have concentrated on using image enhancement techniques. In this work we propose the application of image restoration.#We considered a non-stationary image mode...
Clinical research is important in order to develop new therapies and diagnostic procedures as well as to understand how diseases begin and progress. Observational studies may help identify risk factors for the development of a particular disease, such as the association between smoking and lung cancer...
Classification of microcalcifications in mammograms using artificial neural networks We present results of a new process for generating 1/f type noise sequences and introducing the noise in the primary visual cortex which then enables impro... H Nguyen,WT Hung,BS Thornton,... 被引量: 6发表: ...
Use of the MDL-IIA model resulted in the best diagnostic performance for predicting 4-category molecular subtypes with an accuracy of 88.5%, which was 2.5% higher than the second-best model (Multi-ResNet50+SE). In particular, there were 112 cases with an IHC test result of 2+ (...
MAMMOGRAMSIntroduction: Cystic disease of the breast is very common and present in women aged 35-50 years. They can be detected incidentally or present with lump, pain, or discharge. Confusion occurs in the appropriate classification and management of such cystic...
Types of Divestment Divestment can take various forms, depending on the assets being sold or disposed of. Here are some common types of divestment: Financial Divestment: Selling stocks, bonds, mutual funds, or any other financial investment that supports companies or industries with conflicting practi...
The presence of metastasized cancer in the lymph nodes is may mean the cancer is growing quickly and/or is more likely to spread to other sites. The presence of cancer in lymph nodes often affects prognosis and treatment decisions. Many diagnostic tests look at the lymph nodes as an ...
of cancer is required, it would be less intrusive than other screening approaches like colonoscopies and mammograms and it could be used to follow individuals at high risk for cancer or to monitor the activity of a tumor during treatment. Once the blood test is developed, the scientific ...
Early diagnosis of lung cancers and distinction between the tumor types (Small Cell Lung Cancer (SCLC) and Non-Small Cell Lung Cancer (NSCLC) are very important to increase the survival rate of patients. Herein, we propose a diagnostic system based on sequence-derived structural and physicochemica...
A database of 192 mammograms with 280 true positive detected microcalcification clusters was used for evaluation of the method. The set consisted of cases that were selected for diagnostic work up during a 4 year period of screening in the Nijmegen region (The Netherlands). Because of the high...
