Transcript of Core Curriculum Sonographic Scanning Planes

SONOGRAPHIC SCANNING PLANESby OKSANA H. BALTAROWICH, M.D. Jefferson Ultrasound Research & Education InstituteWe gratefully acknowledge support of this project by the Open Society Institute-New York

BASIC PRINCIPLESWe learn anatomy in standard and crosssectional planes. We scan the body in sections and reproduce a mental 3-D picture of the internal organs. Every organ or area of interest must be scanned in at least two perpendicular planes in order to obtain a 3-D picture.

ANATOMICAL REFERENCE PLANESAnatomical position Erect Facing forward Main reference plane Median sagittal plane

ANATOMICAL REFERENCE PLANESMEDIAN SAGITTAL PLANE Longitudinal, vertical plane Divides the body into right and left halves All sagittal planes are parallel to the median sagittal plane

ANATOMICAL REFERENCE PLANESCORONAL PLANES Longitudinal, vertical planes

Divide the body into anterior and posterior, front and back parts

ANATOMICAL REFERENCE PLANESTRANSVERSE PLANES Horizontal, transaxial planes

Divide the body into superior and inferior, cranial (cephalic) and caudal (tail) parts

ANATOMICAL REFERENCE PLANESOBLIQUE PLANES Inclined from the standard planes In any direction Difficult to describe
