Clinical aspects of imaging and therapy

Regular enrolement

Therapy
Preparation of patients for radiotherapy: choice of patients and consultation, purpose and types of radiotherapy – palliation, radical RT, tele-brachytherapy, patient positioning – purpose, tools, simulation – purpose, types (classical, virtual), practical aspects
Treatment planning: spatial information – purpose, types (historical overview), need for treatment planning, ICRU recommendations, types of treatment planning (2D, 2.5D, 3D), possibilities and limitations
Radiotherapy: treatment beam verification – purpose, types (technical feasibility), dose verification – purpose, types of measurements (advantages, disadvantages)
Radiation damage: radiobiology of tumors and normal tissues, principles of photon and electron radiation damage, tolerance doses for different tissues, mechanisms of radiation damage and clinical manifestations
Selected cases from clinical practice: preparation of the patients with head and neck, lung, colorectal, cervix, and brain tumors
Stereotaxic radiation therapy (SRS and SRT)
Intensity modulated radiation therapy (IMRT)
Image-guided radiation therapy (IGRT)
Imaging
Ultrasound: clinical indications, US images of most common pathological processes, advantages and disadvantages of US technologies
CT: clinical indications, CT images of most common pathological processes, advantages and disadvantages of CT technologies
MRI: clinical indications, MRI images of most common pathological processes, advantages and disadvantages of MRI technologies
Nuclear medicine and PET: clinical indications, nuclear medicine/PET images of most common pathological processes, advantages and disadvantages of nuclear medicine/PET technologies
Use of different imaging techniques in neurology.
