Computed Tomography (CT)

Cardiac computed tomography CT systems use a series of X-ray images to create an image volume dataset that can be sliced or manipulated on any plane using advanced visualization software. This channel includes content on CT scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (also called dual souce or dual energy CT), and interative image reconstruction software that can reduce dose and make lower-quality CT images diagnostic.

Radiation dose monitoring for angiography on the Canon Infinix angiography system. Radiation dose tracking in cardiology.

An example of a real-time patient radiation dose tracking system available for Canon's angiography imaging system. Systems like this can show cumulative dose to the patient's skin as a reminder to rotate the C-arm to new positions to prevent burns during long procedures. These types of systems also can help track patient dose and the location of that dose to be included as part of their electronic patient record. This data also enables quality assurance assessments.

A patient injuried by extreme exposure to X-ray radiation during an angiography procedure, which is included among the images in the American College of Cardiology (ACC) consensus document. Angiography skin burn.

A patient injured by extreme exposure to X-ray radiation during an angiography procedure, which is included among the images in the consensus document. Severe skin injury typically appears four to eight weeks following the exposure. In extreme cases, the ulceration can become confluent and full thickness necrosis of skin may develop, exposing underlying fat, muscle and even bone.
