This published data collection contains reconstructed datasets obtained by X-ray Phase Contrast Imaging (X-PCI) of three different human septal myectomy tissue samples from patients with left ventricular hypertrophy undergoing septal myectomy. Data were collected and processed at the TOMCAT beamline X02DA of the Swiss Light Source. Datasets have been saved in 8bits.

A first series of datasets contains Low Resolution (LR) stitch volumes of the three samples obtained after stitching the LR reconstructions in absorption: 03_HCM080_2_LR_HA_B (10 volumes, 85GB), 06_HCM014_LR_HA_B (10 volumes, 79GB) and 11_HCM054_LR_HA_B (12 volumes, 105 GB).

A second series of datasets contains the single reconstructed High Resolution (HR) volumes of specific areas on those samples (13GB each). To cover areas of interest several volumes were required. Those volumes were reconstructed using the Paganin phase retrieval approach: 05_HCM080_2_HR_disarray_B (4 volumes - disarray area), 08_HCM014_TransM_hor_B (4 volumes - transmural area), 09_HCM014_disarray_B* (4 volumes - disarray area) and 17_HCM054_TransM3_B (6 volumes - transmural area).
