Radiological Imaging Methods

This ppt teaching file is an introduction to the study of radiology for students of medical faculty.
History of radiology, overview of different contemporary imaging methods, their physical principles and future trends of radiology are presented. The second part is dedicated to the static radiological methods of conventional radiography, to radiographic positioning /views/ and to the acquisition of analoque and digital image in radiology.
The presentation is followed by control questions (multi-choice test).

Computed tomography - CT

This ppt teaching file resumes the principle, technical features and current methods of CT examinations in clinical practice. The presentation includes a lot of pictures, which ilustrative shows possibilities of CT and help us understand it´s principles.

Gamma knife

This article includes two powerpoint presentations about radiosurgery. Radiosurgery is a medical procedure that allows non-invasive treatment of benign and malignant tumors. It is also known as stereotactic radiotherapy. Radiosurgery is especially helpful for the localized, highly precise treatment of brain tumors.
