Anterior ViewLateral Head TranslationBilateral Pupils relative to Episternal NotchBisection of pupils relative to episternal notch
Anterior ViewSkull lateral flexion/extensionBilateral pupilsAngle formed by line through pupils relative to plane of shoulders
Anterior ViewLateral Trunk TranslationBisection of trunk at level of T8 relativeLinear distance between the bisection of the trunk and that of ASIS points below
Anterior ViewShoulder AngleAC joints BilateralAngle relative to true horizontal formed by slope of shoulders
Anterior ViewASIS AngleASIS bilaterallyAngle relative to true horizontal formed by slope of ASIS 
Anterior ViewASIS Hip TranslationASIS BisectionBisection of ASIS relative to center of bisection of ankles
Anterior ViewStanding Q-AngleASIS to Patella to tibial tuberosityAngle measured formed by ASIS-Patella relative to patella to tibial tuberosity

Plane of viewVariable of InterestPoints NeededMeasurement Details
Lateral ViewAnterior / Posterior Translation & Angular measurementEAM to base center of neck at approximate level of C7/T1Linear measurement from vertical axis up and then measure distance anterior or posterior to EAM. The angle is also constructed relative to true vertical using these same anatomical locations.
Lateral ViewCVAEAM and  C7 SpinousAngle formed between true horizontal and EAM to C7 spinous
Lateral ViewSkull Flexion/ExtensionLateral Canthus of eye relative to EAMAngle formed relative to true horizontal with lateral canthus of eye relative to EAM
Lateral ViewShoulder Anterior / PosteriorAC Joint relative to greater trochanterAngle formed from AC relative to greater trochanter relative to vertical, and linear distance relative to vertical axis drawn up from greater trochanter
Lateral ViewThoracic KyphosisApproximate C7/T1 to apex of kyphosis to lower thoracic spine approximate level T12/L1Angle formed C7-Apex-T12
Lateral ViewPelvic TiltASIS to PSISAngle formed relative to true horizontal from ASIS to PSIS
Lateral ViewHip Translation and AngleGreater trochanter and lateral malleolus Translation is measurement from vertical axis down from greater trochanter. relative to the knee.  For angle, it is the same points measuring angle
Lateral ViewKnee translation and angleLateral knee relative to lateral malleolusTranslation measurement is from the lateral knee relative distance to ankle, for the angle the same points are used relative to vertical.

Plane of ViewVariable of InterestPoints NeededMeasurement Details
Posterior ViewSkull Lateral FlexionInferior EarPlane through ear markers relative to plane of shoulders
Posterior ViewShoulder angleAC jointsPlane through shoulders relative to true horizontal
Posterior ViewT1-T4, T4-T8, T8-T12, T12-L3Points noted at each levelEach series is measured to true vertical. For example T1-T4 relative to true vertical both linear and angular
Posterior ViewL3-PSIS midpointL3, PSISsL3 to PSIS midpoint – Angle off vertical line through the back Right PSIS & back Left PSIS, distance of L3 offset is calculated to same reference of PSIS midpoint
Posterior ViewAnkle Pronation/SupinationAchilles base of footAngle formed from line from achilles to base of foot and angle measured relative to vertical.
