How it works
NRRD axis 0 varies fastest. Multiply preceding axis sizes by element bytes to obtain strides; sum index×stride for a logical offset. Use exact integer arithmetic.
With ushort sizes 4×3×2, strides are 2,8,24 bytes. Index 1,1,0 begins at byte 10 of the 48 decoded data bytes.
Limits
Header-only calculation, up to 16 axes. This is not a physical file seek: header bytes, line/byte skips, compression and multi-file placement are excluded. No image, spatial orientation or medical interpretation is performed.
