Apodization is a method for reducing side lobes (lateral array elements) in some arrays. It gradually decreases the vibration of the transducer surface with distance from its center by improving the directivity. It is usually accomplished by using more power to excite the innermost elements.

From SIUI Inc.;
'Dedicated to ultrasound industry, Shantou Institute of Ultrasonic Instruments, Inc. (SIUI) has launched Apogee 3500, the Digital Color Doppler Ultrasound Imaging System.
With latest imaging technologies, high-definition image quality and excellent practical functions, the Apogee 3500 offers optimal solutions for clinical ultrasonic examination.'

'The Apogee 3500 is available with many high-density, super broadband and multi-frequency probes, such as convex, micro-convex, linear, vaginal, rectal and phased array probes, which are widely applied for different clinical diagnoses, including abdomen (liver, kidney, gall-bladder, pancreas), gynecology (uterus, ovary), obstetrics (early pregnancy, basic OB, complete OB, multi gestation, fetal echo), cardiology (adult and pediatric cardiology), small parts (thyroid, galactophore, testicles, neonate), peripheral vascular and prostate.'

From SIUI Inc.;
'The Apogee 800Plus ultrasound system offers a new level of high quality in image. With broad clinical application, the system delivers ease of use for cardiac and vascular exams.'
'Due to the exceptional image quality, the sensitivity of color Doppler and many other advanced features, the Apogee 800Plus offers complete diagnosis capability for your entire patient population, including abdominal, obstetrics, gynecology, adult cardiology, pediatric cardiology, peripheral vascular, small parts, breast, prostate, transcranial, etc.'

Arrays are spatial arrangements of transducers or transducer elements.
Array types used in ultrasound imaging:
See also Composite Array.

An array transducer is composed of multiple piezoelectric crystal elements arranged in an array. Arrays are transducer assemblies with a row of elements, used to focus the beam.
