a Schematic of multispectral hemispherical-array-based PACT system used for breast imaging (adapted from ref. 103). b 3D PACT image of a healthy patient’s breast vasculature (left, adapted from ref. 103), and of a breast tumor vasculature (right, adapted from ref. 104) (color encodes depth). c Schematic of the iRAI system, which uses pulsed x-ray excitation with a matrix-array transducer for real-time 3D imaging of radiation dose delivery. d Measured radiation dose delivery using iRAI (left) compared to planned dose delivery (right). The iRAI image is overlaid with the X-ray CT image. c, d are adapted from ref. 109.
