1. Device (100) for radiotherapy, comprising: a megavolt radiation source (108) that emits radiation that passes through the study area (106), and a two-dimensional array of detectors (110) that detects radiation emitted by the megavolt radiation source that passes through the study area； a kilovolt source (110) that emits ionizing radiation that passes through the study area (106), and a two-dimensional array (114) of energy-resolution detectors that detects ionizing radiation that passes through the study area； a tissue tracking module (124) that receives a first image of a tissue of interest and a second later acquired spectral image of a tissue of interest, and tracks a change in the geometry and / or location of the tissue of interest based on at least the first and second images, and generates a signal indicating a specified change, and the second later received spectral image is formed on the basis of the first spectral signal corresponding the output of a two-dimensional array of detectors with energy resolution for the first specified energy range, and a second spectral signal corresponding to the output of a two-dimensional array of detectors with energy resolution for the second specified energy range, the second later received spectral image visually enhances the scanned structure corresponding to the first or second signal while visually suppressing another scanned structure corresponding to another from the first or second signal als； imodul (126) adapt1.
