The possibilities for monitoring phase transitions in single crystals using limited sections of data are considered. Specifically, the novel technique of monitoring phase transitions using a single three‐dimensional data frame measured by the time‐of‐flight Laue technique has been investigated using simulations. These have shown there is real potential in this technique, allowing `dynamic' measurements of single‐crystal materials. The time‐of‐flight Laue technique is shown to be of particular utility in this area and the possibilities for single‐shot monitoring of phase transitions are assessed, evaluated
