Dual-Modality X-Ray-Induced Radiation Acoustic and Ultrasound Imaging for Real-Time Monitoring of Radiotherapy

Figure 4

Demonstration of the feasibility for xRAI and US dual-modality imaging via imaging of lards in gel: (a) experimental setup; (b) grayscale US image showing the structure of the phantom with three lard blocks to be targeted separately by the X-ray beam; (c–e) pseudocolor xRAI images, superimposed on the grayscale B-mode image, showing in red the boundaries of the separately deposited X-ray dose in the top through bottom lard blocks, respectively.
