A method and system for performing online adapted radiotherapy are provided using combined ultrasound and ionizing radiation induced acoustic imaging (iRAI) computed tomography imaging techniques that can be used for measurement of low to ultrahigh dose deliveries (40 Gy/s). Multiplexed transducers detect US and iRAI signals allowing for anatomical/functional imaging and radiation mapping with absolute dosimetry measurements of a region of interest during a radiotherapy session. Corrections to radiation dosage intensities and locations is determined and provided as feedback to a radiation source to improve the accuracy of applied radiation dosages intra- or inter-radiotherapy treatment sessions preventing the irradiation of healthy tissues and ensuring the accurate delivery of radiation to a tumor or region of interest.
