Knowledge points:

The Siemens P4-2 Phased Array transducer has a frequency range of 1.8 MHz. - 3.6 MHz. and supports the following applications: Cardiac, Abdominal, Obstetrics, and Gynaecology. The Siemens P4-2 transducer is compatible with: Siemens Acuson X300; Siemens Sonoline G40; Siemens Acuson X500; Siemens Sonoline G60S; and Siemens Sonoline G50 ultrasound systems.

Harmonic imaging

Harmonic imaging exploits non-linear propagation of ultrasound through the body tissues. When the frequency of emitted sound wave is f 0, the frequency of echo (due to reflection or scattering) includes f 0 (called fundamental wave), 2f 0, 3F 0 and so on The second harmonic (2f 0) has the largest energy.

Ultrasonic harmonic imaging (UHI) is based on the information of human body carried by the second harmonic in echo (reflection or scattering). Harmonic imaging without UCA is called native harmonic imaging or tissue harmonic imaging. Harmonic imaging using UCA (ultrasound contrast agent) is called contrast harmonic imaging.

Multi-frequency probe

Multi-frequency probe is a new development of pulse-echo transducer. The probe can send out several different ultrasonic pulses, so as to cover the near field with high-frequency ultrasound, the intermediate-frequency ultrasound to cover the transition zone between the far and near fields, and the low-frequency ultrasound to cover the far field. The unit multi-frequency probe is to bond multiple layers of piezoelectric ceramics (or polymer piezoelectric materials) to each other, and lead wires from the electrodes between each layer to obtain multiple frequency ultrasonic pulse emission through exciting different layers . The digital coding of the multi-frequency probe is simple but easy to lose the signal.

Storage for Transport of ultrasonic transducer

• Make sure that the transducer is clean and disinfected before placing it in the case to avoid contaminating the foam that lines the carrying case.
• Place the transducer in the case carefully to prevent kinking of the cable.
• Before closing the lid, make sure no part of the transducer is protruding from the case.
• Wrap the case in plastic material containing sealed-air pockets (such as Bubble Wrap material), and pack the wrapped case in a cardboard carton.
