Rotationsaufnahme

Rotationsaufnahme is a technique used in medical imaging, particularly in computed tomography (CT) and digital subtraction angiography (DSA), where the X-ray source and detector rotate around the patient. This allows for the acquisition of multiple projections of the anatomy from different angles in a single examination. In CT, this rotation enables the reconstruction of cross-sectional images, providing detailed views of internal structures. For DSA, the rotational movement captures images before and during the injection of contrast media, allowing for the isolation and visualization of blood vessels by subtracting the background anatomy. This method is crucial for diagnosing a wide range of conditions, including tumors, vascular abnormalities, and internal injuries, by offering a comprehensive 3D understanding of the patient's anatomy. The continuous movement of the source and detector can also speed up image acquisition, reducing motion artifacts and improving patient comfort.
