3.7.2.2. Array elements

| top | pdf |

Data items in this category are as follows:

ARRAY_ELEMENT_SIZE [Scheme scheme2]

The bullet ([\bullet]) indicates a category key. The arrow ([\rightarrow]) is a reference to a parent data item.

The value of the _array_element_size.size data item is a size in metres of an image element (a pixel or voxel). The direction of the measurement is given in each dimension by _array_element_size.index. The array structure specifying the organization of the dimensions is referenced by the value of _array_element_size.array_id, which is a pointer to _array_structure.id. The value of _array_element_size.index is a pointer to _array_structure_list.index. For data organized into rectangular arrays of pixels or voxels, this gives the spatial dimensions of the individual image elements.
