Axial CT scans provide comprehensive imaging data important for treatment planning in radiation therapy, which includes several key elements.

Firstly, tumor target volume is delineated from the imaging, allowing radiation oncologists and dosimetrists to identify the extent of the tumor. This is crucial for ensuring that the prescribed radiation dose effectively targets the tumor while minimizing exposure to surrounding healthy tissues.

Secondly, the external patient contour can be assessed from these scans. Understanding the contour helps in accurately positioning and planning the radiation delivery, taking into account the unique anatomical features of each patient’s body.

Lastly, axial CT scans are instrumental in measuring the volumes of critical organs within the area of interest. This information is vital for creating treatment plans that aim to spare these organs from excessive radiation dose, which could lead to complications or long-term adverse effects.

In essence, axial CT scans provide a wealth of patient-specific data: the tumor target volume, external contour, and critical organ volumes all contribute to developing a tailored and effective radiation treatment plan. Thus, the inclusion of all these elements demonstrates the comprehensive insight provided by axial CT imaging, making the response that encompasses all aspects the correct choice.
