State-of-the-art hybrid pixel semiconductor detectors provide excellent imaging properties such as unlimited dynamic range, high spatial resolution, high frame rate and energy sensitivity. Nevertheless a limitation in the use of these devices for imaging has been the small sensitive area of a few square centimetres. In the field of microtomography we make use of a large area pixel detector assembled from 50 Timepix edgeless chips providing fully sensitive area of 14.3  7.15 cm2. We have successfully demonstrated that the enlargement of the sensitive area enables highquality tomographic measurements of whole objects with high geometrical magnification without any significant degradation in resulting reconstructions related to the chip tilling and edgeless sensor technology properties. The technique of micro-tomography with newly developed large area detector is applied for samples formed by low attenuation, low contrast materials such as phacelia tanacetifolia seed, a carbonized wood sample and beeswax seal sample.
