  1. Using ‘obi:value specifications’for Measurements in RadiologyHeiner Oberkampf Legend: owl:Class rdf:type instance everything in red is to be discussed

  2. Using ‘obi:value specification’ “Enlarged lymph node with diameter 1.1 cm.”@en mci:sentence mci:has textual representation _:s ogms:clinical finding fma:lymph node mci:documented in _:cf iao:is about _:ln Size in PATO: ro:has_part bfo:has quality pato:diameter iao:length measurement datum _:diam-LN iao:is quality measurement of obi:value specification _:md :length value specification uo:length unit obi:has value specification Added Classes: uo:centimeter _:vs iao:has measurement unit label obi:has specified value “1.1”^^xsd:float

  3. Using ‘obi:value specification’ for2D measurements “Enlarged lymph node with diameter 2.5 x 1.1 cm.”@en mci:sentence mci:has textual representation ogms:clinical finding fma:lymph node _:s mci:documented in _:cf iao:is_about _:ln bfo:has quality pato:diameter ro:has_part iao:measurement datum _:diam-LN :two directional length measurement datum _:diam-LN2 iao:length measurement datum obi:value specification iao:is quality measurement of _:2d-lmd :length value specification ro:has_part uo:length unit _:md _:md2 obi:has value specification uo:centimeter iao:has measurement unit label _:vs _:vs2 “1.1”^^xsd:float obi:has specified value “2.5”^^xsd:float

  4. NormalSize Specifications

  5. Normal Size Specifications Example: Lymph nodes are normally up to 1 cm. Added Classes: Added Object Properties: Instances: 96 size specifications about 38 different anatomical entities. pato:normal pato:size pato:length fma:lymph node pato:diameter _:nd bfo:is quality of _:ln iao:information content entity obi:value specification obi:scalar value specification :normal size upper bound specification iao:is quality specification of :length value specification uo:length unit _:ns _:vs iao:has measurement unit label uo:centimeter :has maximal value specification obi:has specified value “1.0”^^xsd:float

  6. Using Defined Classes normal size interval specification normal size upper bound specification …

  7. Work in Progress • Orientation of the measurement within the three planes: • longitudinal (cranio-caudal, superior-inferior) • transverse (axial) • antero-posterior • Type of size measurement • length, width, depth, height, thickness… • long/short diameter • Location of the measurement • “Lesion of 1.8 cm in liver segment 6.” • “Diameter of spleen at hilum.” • Questions • OBI is using BFO(2?) while IAO is using BFO1.1… ??? • OBI contains two DataProperties ‘iao:has measurement value’ and ‘obi:has specified value’: • Is the IAO property still needed? • Could one use the IAO property as a shortcut for the path ‘obi:has value specification’/‘obi:has specified value’?
