2.4 Structure
TEEtransducerisaphasedarraytransducer,mountedinasealedtipattheendofa
gastroscope.Thetransducerisintendedforimagingoftheheartthroughtheesophagus
andthestomach.Amongthem,thetipofP7-3T/P7-3Ts/P7-3TE/P7-3TU/P8-2Ts/P8-2TU
rotatesusingthemotorcontrolpush-buttononthecontrolhandle,thetipofP8-3Tsrotates
usingthescanplanerotationwheelonthecontrolhandle,andthetipofXP8-2TUrotates
usingthecontrolpush-buttonsonthecontrolhandleelectronically.
Theprobetiprotatesusingthedeflectioncontrolwheelonthehandleforaccurate

1 Distaltipwith
transducer
Convertstheelectricalsignalintoanultrasonic
signal,focusingthesoundbeamsinagivendirection;
meanwhile,itreceivesthereectedultrasonicsignaland
convertsitintoanelectricalsignalfortransmissionover
thecable.Thelensonthesurfaceistheacousticlens.
Applyultrasoundgelontheacousticlensforcorrect
operation.
