The smallest uncertainty was associated with the estimate of the position of the N-nasion (0.05 mm), while the largest uncertainty was associated with Ft_l, the left frontotemporal skin landmark (1.14 mm).
When it is not feasible to use MR-visible capsules during MR imaging to allow skin landmark-based co-registration of the measured EEG electrode positions to the MR-derived head model, co-registration of electrode positions may depend on an initial visual co-registration.
The purpose of this study was to rate clinically and to assess objectively some variations in the skin surface landmarks on the dorsal hands of menopausal women over a 11-month period.
We analyzed reflecting markers glued to the skin on anatomical landmarks.
The most common esthetic signs of facial aging include visibility of bony landmarks, skin wrinkles, deep furrows, prominence of nasolabial folds, perioral vertical rhytids, ptosis of the oral commisures, and thinning of the lips.
Snowdrifts can hide familiar landmarks.
Besides, the removal of muscle and skin to expose bony landmarks and to avoid skin movement errors may have allowed the joints to deviate slightly from their anatomical sagittal plane.
10 mm reflective markers were attached to the skin overlying specific anatomical landmarks: lateral fifth phalange, lateral humeral epicondyle, ulnar styloid process, greater trochanter of the femur, lateral femoral epicondyle, lateral malleolus of the tibia, and the interscapular region dorsal to vertebra C7.
Subsequently, using a combination of spatial translation and rotation hand gestures, the operating surgeon manipulated the virtual anatomy from a static posture until a satisfactory degree of anatomical landmark and skin outline alignment against the anaesthetised patient were achieved.
I carefully went over my bony landmarks, noted the skin folds, and performed all the many tests physical therapy professionals do to isolate muscles, tendons, bones and other structures during an examination.
