Abstract (en)
[origin: WO9726507A1] Apparatus and method for monitoring a system in which a fluid flows and which is characterized by a change in the system with time in space. A preselected place in the system is monitored (14) to collect data at two or more time points (12) correlated to a system event. The data is indicative of a system parameter that varies with time as a function of at least two variables related to system wash-in and wash-out behaviour (15). A calibration map is made (20) on a culculated basis with each pixel or voxel representative of a color hue indicative of wash-out behaviour (19) and a color intensity indicative of wash-in behaviour (16). When a satisfactory map is obtained, the collected data is processed on the basis of the map to obtain an image of the preselected place with each spatial unit thereof correlated with a color hue and a color intensity. Software and a data processing system are provided to develop the calibration map. The calibration map and image of the preselected place are also novel implementations.
