Ultrasound is an ideal tool to examine the joints and surrounding soft tissues like tendons, ligaments and joint linings. Musculoskeletal and joint sonography is sensitive, without radiation exposure, easy accessible, quick, and has high patient tolerability with relatively low cost.
A real-time scanner allow the dynamic assessment of the musculoskeletal system and a specific examination for each patient. In addition, joint aspiration and injection accuracy can be improved. Probes with high frequency improve the image resolution and allow visualization of fine anatomic structures of the small parts. As musculoskeletal ultrasound (MSUS) is very operator dependent, experience and training is required. Ultrasound is also often used in the treatment of musculoskeletal disorders.

From ESAOTE S.p.A.;
'The MyLab™30CV ultrasound system is an evolutionary step in ultrasound technology. Weighing less than 20 pounds, it is the first compact ultrasound system to deliver premium console performance. And with mobile, portable or stationary configurations, MyLab30CV can adapt to any clinical environment.'

The propagation of high amplitude ultrasound waves is inadequate described by a linear wave equation. Non-linear propagation is to expect if the power levels are high enough to make non-linear effects significant. A non-linear propagation results in the distortion of the transmitted waveforms, resulting in the generation of harmonics of the initial frequency components transmitted by the transducer.
In the near field of ultrasound probes, the occurring diffraction and focusing effects make this process complex. The distortion of a wavefront propagating in a medium in which the compressional phase moves slightly faster than the rarefactional phase, results is the conversion of some wave energy into higher harmonics of the fundamental frequency. The effect increases strongly with increasing wave amplitude.

A phased array probe applies voltage pulses to all elements as a group but with small time differences (phasing). The time difference is changed each time so that the sound pulses will be sent out in different directions.

Pregnancy ultrasound plays a crucial role in monitoring the health and development of the fetus throughout pregnancy. It serves as a screening tool with various applications, including:
