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

Figure 7

xRAI and US real-time dual-modality imaging of an in vivo rabbit liver, demonstrating the capability for tracking tissue movement with respect to the X-ray beam. (a) The setup for validating the capability of the system in real-time tracking the movement of the target tissue with respect to the position of the X-ray beam illuminating on a live rabbit. (b) The xRAI and US combined images at different time points (1, 11, 21, 31, and 41 seconds) during the real-time imaging over a period of 50 seconds. In each combined image, the xRAI image in pseudocolor presenting the location of the X-ray dose deposition (marked by the yellow dashed box) is superimposed on the US image in grayscale showing the tissue structure.
