(6)6 Patients position
• Patients lay face up on scanning table, put a cushion under patients head in order to spread mammary gland spread evenly
• Nipple point up and at the central of mammary gland • Raise patients have above their head
• Patients head turn to not scanning side

• Decribe scanning area
‐ Have middle mammary gland: included nipple at central.Have middle mammary gland: included nipple at central
Scanner postion
• Nipple pointing arrow in middle of scanner in corresponding position with
AP view
corresponding position with nipple
• Scanner position at lower edge of nipple
• Put pressing table from above to put pressure on mammary gland in order to flatten mammary gland
(9)Lateral view
• Describe scanning area:
Lateral linear: include linear from Lateral linear: include linear from middle axillary line and lateral edge of breast Nipple will be in inner lower conner of stabilized film

Scanner position
• Technician move to opposite side and scanner move along g
• Place inner edge of scanner straight in middle line of sternum and take 2cm above breast fold Put pressure and push scanner toward outer edge of breast but guarantee scanner contact with mammary gland ( don’t have space for air to come in)
Ni l t f d • Nipple at upper area of scanner and
right above nipple positioning arrow • ush press button depend on how much
patients can handle
(11)Additional position (INF, SUP, UOQ)
Meaning of additional position
• INF position: additional for missing part under breast fold.
• SUP position : additional for missing part in above( if breast is too big and mammary fill up above) • UOQ position: additional to axillary tail (if patients

(13)Image asscessment
• All mammary gland need to be expose according to scan position Guarantee to take all mammary gland in all direction. position Guarantee to take all mammary gland in all direction • Nipple at middle position in AP position, at lower under
conner in LAT position, at upper middle in MED position (compare to nipple positioning arrow)
• Image don’t be affected by motion artifact or air bubble
