X‐ray‐induced acoustic computed tomography for guiding prone stereotactic partial breast irradiation: a simulation study

Abstract: The aim of this study is to investigate the feasibility of x-ray-induced acoustic computed tomography (XACT) as an image guidance tool for tracking x-ray beam location and monitoring radiation dose delivered to the patient during stereotactic partial breast irradiation (SPBI). Methods: An in-house simulation workflow was developed to assess the ability of XACT to act as an in vivo dosimetry tool for SPBI. To evaluate this simulation workflow, a three-dimensional (3D) digital breast phantom was created by a ser… Show more

“…While RAI has been predominantly validated in conventional radiotherapy (Xiang et al 2012, Sampaio et al 2015, Kim et al 2017, Lei et al 2018, Zheng et al 2020, Zhang et al 2023, confirming its linearity in the FLASH regime is crucial. For the first time, we have extended RAI imaging to FLASH-RT, testing doses up to 5 Gy per pulse, which is 5000 times stronger than the doses typically used in conventional radiotherapy.…”

“…Cerenkov radiation provides a viable option for surface in vivo dosimetry (Glaser et al 2013, Jarvis et al 2014, it falls short in monitoring deep-seated tumors. Recent advancements in radiation-induced acoustic imaging (RAI) have shown promise for in vivo dosimetry in treating tumors deep inside the patient (Ahmad et al 2015, Patch et al 2016, Kim et al 2017, Lei et al 2018, Hickling et al 2018b, Zheng et al 2020, Zhang et al 2023.…”

“…However, due to the high computational time associated with the ITR algorithm, it has limited clinical applicability. In a recent numerical study [28], the potential of XACT for tracking the X-ray beam and in vivo dosimetry during stereotactic partial breast irradiation [29] was examined. Wang et al carried out simulations to demonstrate the feasibility of using a transperineal (planar) ultrasound transducer array for XACT imaging to monitor prostate radiotherapy [30].…”
