the section of tissue through which the ultrasound beam is passing during the scan

used to examine interrnal body structures

short in height, broad shoulders and hips, short torso. stomach is very high and almost horizontal. gallbladder is away from the midline. lungs are short, and the diaphragm is high. emptying the stomach is very fast. stomach level is thoracic 9 - 12 with the center about 1 inch(2.5 cm) distal to the xiphoidal process. comprise of 5% population

slender, comprise of 35% population. narrow and longer lungs with low diaphragm. stomach T11-L5 or even lower. vertical stomach, duodenal bulb near the midline at the level of L3 or L4

very slender body type. GB near the midline. stomach slow emptying, comprise of 10% of the population. stomach level of T11-L4. duodenal bulb at L3-L4 to the left of midline

athletic tyoe. average body type. stomach is "J" in shape. T10 or T11-12. duodenal bulb level of lumbar 1 - 2. comprise of 50% of population

4 planes of the body

transpyloric plane is also known as

is an upper transverse line located halfway between the jugular notch and the upper border of the pubic symphysis. the plane cuts through the stomach, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebrae

the ultrasound beam is entering the body from either right or left lateral direction and that the anatomic portion of body structures being visualized from that particular direction are lateral, medial, superior, inferior

this plane will literally leave you with front and back portion.
a plane that runs vertically from the top to bottom, and it divides the body in to a front side and back side (a-p)
dorsal and ventral

divides the body into cranial and caudal (head and tail) portions

coronal scanning plane directions

the utz beam is entering the body from either anterior or posterior direction and that the anatomic portion of body structures being visualized from that particular direction are anterior, posterior, superior, inferior

sagittal scanning plane directions
