Background Central nervous system CNS malformations are one of the most common congenital abnormalities. Ultrasound has been used for nearly 30 years as the major imaging modality to help diagnose fetal CNS anomalies [1]. The orientation of the Mid-Sagittal Plane provides a unique view of the intracranial structures such as the corpus callosum CC and an axial view of the cerebellar vermis CV.

Breast cancer[ edit ] CAD is used in screening mammography X-ray examination of the female breast. Screening mammography is used for the early detection of breast cancer. CAD systems are often utilized to help classify a tumor as malignant or benign.

Craftsmen Training Scheme (CTS)

CAD is especially established in US and the Netherlands and is used in addition to human evaluation, usually by a radiologist. The first CAD system for mammography was developed in a research project at the University of Chicago.

Today it is commercially offered by iCAD and Hologic. There are currently some non-commercial projects being developed, such as Ashita Project, a gradient-based screening software by Alan Hshiehas well.

However, while achieving high sensitivities, CAD systems tend to have very low specificity and the benefits of using CAD remain uncertain.

Some studies suggest a positive impact on mammography screening programs, [14] [15] but others show no improvement. However, it noted considerable heterogeneity in the impact on recall rate across studies.

Lung cancer bronchial carcinoma [ edit ] In the diagnosis of lung cancer, computed tomography with special three-dimensional CAD systems are established and considered as appropriate second opinions. Today all well-known vendors of medical systems offer corresponding solutions.

Early detection of lung cancer is valuable. Lung cancer takes more victims than breast cancer, prostate cancer and colon cancer together.

This is due to the asymptomatic growth of this cancer. In the majority of cases it is too late for a successful therapy if the patient develops first symptoms e.

Indeed, the random detection of lung cancer in the early stage stage 1 in the x-ray image is difficult. Colon cancer[ edit ] CAD is available for detection of colorectal polyps in the colon in CT colonography. CAD detects the polyps by identifying their characteristic "bump-like" shape.

To avoid excessive false positives, CAD ignores the normal colon wall, including the haustral folds. This, for example, can be used for chest pain patients' triage in an emergency setting. Congenital heart defect[ edit ] Early detection of pathology can be the difference between life and death.

CADe can be done by auscultation with a digital stethoscope and specialized software, also known as Computer-aided auscultation.

Murmurs, irregular heart sounds, caused by blood flowing through a defective heart, can be detected with high sensitivity and specificity. Computer-aided auscultation is sensitive to external noise and bodily sounds and requires an almost silent environment to function accurately.

Pathological brain detection PBD [ edit ] Chaplot et al. Their feature vector of each image is created by considering the magnitudes of Slantlet transform outputs corresponding to six spatial positions chosen according to a specific logic.Computer-Aided Examination System Essay Sample.
