A touch-sensitive apparatus comprises a panel for conducting signals from incoupling points to outcoupling points. Actual detection lines are defined between pairs of incoupling and outcoupling points to extend across the panel. A signal generator is coupled to the incoupling points to generate the signals, e.g. light, and a signal detector is coupled to the outcoupling points to generate an output signal. A data processor processes the output signal to generate a set of data samples, which are non-uniformly arranged in a two-dimensional sample space. Each data sample is indicative of detected energy on a detection line and is defined by a signal value and first and second dimension values in the sample space. The first and second dimension values define the location of the detection line on the surface portion. Adjustment factors are obtained for the data samples, each adjustment factor being representative of the local density of data samples in the sample space. The data samples are processed by tomographic reconstruction, while applying the adjustment factors, to generate a reconstructed distribution of an energy-related parameter
