They have two functions: 

During transmission, electrical energy from the ultrasound machine is converted into sound.
During reception, the reflected sound pulse is converted into electricity. ]]> 2022-12-12 02:14:28 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2417190864 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2417240358 2022-12-12 03:16:50 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2417240358 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2417250027 2022-12-12 03:31:29 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2417250027 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418154324 2022-12-12 17:49:10 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418154324 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418155072 Interesting Note: Phased array always means "adjustable" or "multi-focus."

With these settings, the sonographer could not make any changes. In more modern linear sequential arrays focusing is attained electronically through electronic phase delays. 

Electronic transmit focusing is done by a curved pattern of the active element being fired. The curved pattern is achieved by the outer active elements being fired earlier than the inner elements. 

Receive focusing is done by electrical delays in the returning signals. ]]> 2022-12-13 01:59:20 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418587962 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418591520 2022-12-13 02:03:49 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418591520 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418605984 2022-12-13 02:19:41 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418605984 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418614819 2022-12-13 02:29:59 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418614819 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418626591 2022-12-13 02:44:06 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2418626591 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419892390 2022-12-14 00:13:44 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419892390 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419901881 2022-12-14 00:27:30 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419901881 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419909847 2022-12-14 00:35:06 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419909847 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419915913 2022-12-14 00:42:31 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419915913 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419923863 2022-12-14 00:52:53 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419923863 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419936181 2022-12-14 01:08:19 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419936181 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419955511 2022-12-14 01:27:40 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419955511 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419958882 2022-12-14 01:31:23 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419958882 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419961622 Think of external focusing as a pair of eyeglasses and internal focusing as Lasik. ]]> 2022-12-14 01:34:23 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419961622 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419966159 2022-12-14 01:39:55 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419966159 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419975504 Convex probes have a wider field of view at a lower frequency and are mostly used for abdominal imaging because of the deep depths it can penetrate. ]]> 2022-12-14 01:50:33 UTC https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419975504 rcrouch02 https://padlet.com/rcrouch02/rcctvgrh751yfb97/wish/2419980446 Vector transducers are good for scanning large structures deep in tissue, such as the kidneys.
