Introduction: Ultrasound diagnostics is based on the emission, detection and to display acustic energy that echoes fromdifferent structures in the body. The acquired data is used to display high resolution gray-scale images of the body. We can also show the blod flow. For the procedure to take place we use an ultrasonic probe. To capture the image we use different methods such as A-mode, B-mode, M-mode and Doppler effect imaging technique. We use a central procesing uni to interpret the acquired data in display them on the screen. Artificial intelligence is a growing phenomenon in radiology and it has shown promising results in detecting, differentiating and determening pathologies. Artificial intelligence helps health workers with tasks that require a lot of time and detailed analysis of high volume of data. Purpose: Purpose of the diploma work is to study how artificial intelligence is used in ultrasound diagnostics. Specifically in the ultrasound examinations of the liver, thyroid, breasts and in the gynecological area. Methods: We used a systematic review of literature method. The literature was acquired from the following data bases Google Scholar, ScienceDirect and PubMed. The articles were found using including and excluding criteria. Results: After a thorough analysis of the selected literature we presented the artificial inteligence model that was used in the article and what was its purpose. Artificial inteligence is used in ultrasound diagnostics as a detection, diagnostic and classification tool for different pathologies. The best artificial inteligence model for detection and diagnosing focal liver lessions turned out to be ResNet50. The model LivGuard was used for cirhosis classification For the ultrasound diagnostics of the thyroid, the best model used was ResNet-34 for detection of thyroid nodules. The best AI models used for diagnosing thyroid nodules were Xception and CNN-VGG. These models showed similar results. The best diagnostic model for diferentiating between benign and malignant breast lession were CNNE1, CNNE2, CNNE3 and BU-CAD with similar results. The best classificator between benign and malignant ovary lessions was Ovry-Dx2. A DLR model was used for helping with the diagnosis of endometrium cancer and the model YOLOv8 was used for detecting endometrium cancer on ultrasound images. Discussion and conclusion: Artifical intelligence poses great potential in ultrasound diagnostics. Currently it is mainly used for classification, detection and diagnosing of different pathologies. Even though artificial intelligence models achive good results, some even better than experienced radiologists, they are not yet tested enough on bigger trials with more data to be used as an independently in diagnostics. From the articles we can conclude that artificial inteligence is on a good way to make the ultrasound procedure fully automatic, but it is not yet ready to replace an experienced radiologist.
