The history of CAD is roughly divided into four generations as explained in Section 2, and the discussion is made in terms of these generations. The third generation is de ned for product modeling. Product modeling is a key technology used in CAD which are now spreading in industry, so I introduce some of the important concepts of product modeling in Section 3. Finally I will discuss about the ...

A fully automatic technique for segmenting the liver and localizing its unhealthy tissues is a convenient tool in order to diagnose hepatic diseases and assess the response to the according treatments. In this work we propose a method to segment the liver and its lesions from Computed Tomography (CT) scans using Convolutional Neural Networks (CNNs), that have proven good results in a variety of...

Stimulated Raman histopathology with computer aided diagnosis.

Skin cancer is the most common form of cancer in North America, and melanoma is the most dangerous type of skin cancer. Melanoma originates from melanocytes in the epidermis and has a high tendency to develop away from the skin surface and cause metastasis through the bloodstream. Early diagnosis is known to help improve survival rates. Under the current diagnosis, the initial examination of th...

Water resonance lineshapes observed in breast lesions imaged with high spectral and spatial resolution (HiSS) magnetic resonance imaging have been shown to contain diagnostically useful non-Lorentzian components. The purpose of this work is to update a previous method of breast lesion diagnosis by including phase-corrected absorption and dispersion spectra. This update includes information abou...

purpose: hidden caries is a term used to describe occlusal dentine caries that is missed on a visual examination, but can be detected by bitewing radiographs. the aim of this study is the review of new studies about this lesion and presentation the ways for diagnosis, prevention and treatmen of this lesion. review of literature: investigations believe that the etiology of this lesion is the mor...

Mammography is widely recognized as the most reliable technique for early detection of breast cancers. Automated or semi-automated computerized classification schemes can be very useful in assisting radiologists with a second opinion about the visual diagnosis of breast lesions, thus leading to a reduction in the number of unnecessary biopsies. We present a computer-aided diagnosis (CADi) syste...

Computer-aided detection (CADe) and diagnosis (CAD) has been a rapidly growing, active area of research in medical imaging. Machine leaning (ML) plays an essential role in CAD, because objects such as lesions and organs may not be represented accurately by a simple equation; thus, medical pattern recognition essentially require "learning from examples." One of the most popular uses of ML is the...

Evaluation of articular cartilage and subchondral bone is essential in the diagnosis of joint diseases and injuries. Interobserver and intraobserver reproducibilities of arthroscopic grading are only poor to moderate. Thus, for quantitative and objective evaluation of cartilage and subchondral bone, ultrasound arthroscopy (UA) has been introduced to clarify this dilemma. Assessment of the clini...

Magnetic resonance imaging (MRI) is a sensitive diagnostic method in improving the diagnostic capacity for hepatic cirrhosis and determining the accurate characterization of hepatic cirrhosis. But hepatic MRI has some shortcomings in detection and classification hepatic cirrhosis in clinical, especially using non-enhanced MRI for diagnosing early hepatic cirrhosis. And computer-aided diagnostic...
