Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

A radiotherapy treatment plan for Accuray’s Tomotherapy system to kill white blood cells prior to a liver cancer patient undergoing a transplant. The treatment is aimed at the bone marrow and spares dose to most of the organs to reduce side effects. This was an example plan created on the new Volvo Ultra treatment planning system. The software allow planning for more than 100 cm of anatomy. It also allows users to drag target dose values of the main graph and the system will recalculate all the doses.

Cardiac CTA derived left atrium emptying fraction (LAEF) improves predictive performance of established clinical risk scores and may be used to assess TAVR patient risk during pre-procedure workup and post-procedural surveillance. These images show LAVmax (A and B), LAVmin (C and D), and LAEF using cardiac CTA. LAEF was calculated as (LAVmax-LAVmin)/LAVmax x 100. Given LAVmax of 109 mL and LAVmin of 80 mL, the LAEF was calculated to be 27%. Image courtesy of AJR.
