Height Difference
Toolbar > Measure > Height Difference. Measure the vertical distance and angle between the horizontal line and the line connecting the points:
CTR (cardiothoracic ratio)
Toolbar > Measure > CTR (cardiothoracic ratio). CTR to measure a cardiothoracic ratio to estimate a heart size:
Watch the video tutorial on how to measure the cardiothoracic ratio with DICOM Viewer:
CTR measurement is used to measure the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter and aids in the detection of enlargement of the cardiac silhouette.
Flatfoot
Toolbar > Measure > Flatfoot. Measure the longitudinal arch of the foot to detect the longitudinal flatfoot:
Foot longitudinal arch measurement is used to measure the angle and height of the foot medial longitudinal arch and aids in the detection of the longitudinal flatfoot.
Goniometry
Toolbar > Measure > Goniometry. Measure the lengths of the femur, tibia, and femoral-tibial angular deformities:
TT-TG Distance
Toolbar > Measure > TT-TG Distance. Measure the tibial tuberosity to trochlear groove distance for quantifying the knee patellar instability:
Vertebra Angle
Toolbar > Measure > Vertebra Angle. Measure an angle between the user-drawn vertebra axis and the horizontal axis of the image:
