What is one function of a CT simulator?

A CT simulator is primarily designed for treatment planning in radiation therapy and is crucial for ensuring accurate targeting of tumors while sparing surrounding healthy tissues. One of its main functions is to reconstruct images in any plane using axial scans. This capability enables the dosimetrist and radiation oncologist to visualize the anatomy of the patient in multiple orientations (axial, sagittal, and coronal) which is essential for precise treatment planning.

Using axial scans, the CT simulator can create detailed three-dimensional images that allow for the assessment of tumor size, location, and relationship to surrounding critical structures. Such comprehensive imaging is critical for planning radiation dose distributions accurately and effectively. The ability to manipulate and view the images in various planes enhances the understanding of the spatial relationships within the patient's anatomy, which is crucial in developing an optimal treatment plan.

The other functions listed, such as providing live images during surgery or diagnosing fractures, do not pertain to the primary role of a CT simulator in the context of medical dosimetry and radiation therapy planning. Real-time imaging during treatment also falls outside the scope of the CT simulator's capabilities, as its focus is on pre-treatment imaging rather than intra-treatment monitoring.
