Abstract
The present embodiments relate generally to increasing the precision of radiotherapy by measuring the absolute dose delivered to the tumor and surrounding normal tissue during the treatment. More particularly, some embodiments relate to an imaging reconstruction system for X-ray-induced acoustic computed tomography (XACT) using a model-based reconstruction method. Instead of reconstructing relative dose information for radiation beam localization, the system is capable of reconstructing absolute in vivo dose information. The XACT absolute in vivo dosimetry tool holds great potential for personalized cancer treatment and better outcomes. In some embodiments, thermal parameters, such as Gruneisen parameters, are used to convert reconstructed pressure information to dose. In addition, to avoid problems caused by electrical system gain, calibration tools, such as ion chambers, can be used to calibrate the system.
