Pixel Spacing Metadata

When contributing CT/MRI media data to MorphoSource, the fields X pixel spacing, Y pixel spacing, and Z pixel spacing are mandatory and must be completed. Providing pixel spacing information is critical for maintaining discoverability, accessibility, reusability of your data. If pixel spacing is supplied incorrectly, not only will the scale and proportions of image previews created by MorphoSource be wrong, but the scale and proportions of volumetric images created by future researchers who access your data will also be wrong. This could lead to other users being unable to work with the data, or worse: it could lead to inaccurate representations of the specimen or object you have imaged in future literature, inaccurate observations or measurements reported for that specimen or object, and/or inaccurate scientific predictions or conclusions based on those observations. This section will help explain pixel spacing of CT/MRI images and guide you in locating these crucial values.
