Ultrasound machines, widely used in medical imaging, are essential tools in the field of diagnostic ultrasound. These devices utilize high-frequency sound waves to create real-time images of internal body structures. Ultrasound machines consist of several key components that work together to generate diagnostic images. These include:
B-mode machines represent the vast majority of machines used in echocardiology, obstetrical scans, abdominal scans, gynecological scans, etc. B-mode ultrasound machines usually produce the sector (or pie segment-shaped) scans. These ultrasound scans require either a mechanical scanner transducer (the transducer moves to produce the sector scan), or a linear array transducer operated as a phased array.


Ultrasound machines come in different types, each catering to specific clinical needs. The two primary types are stationary and portable ultrasound machines:

Ultrasound technology has evolved significantly, providing sonographers with a wide range of ultrasound machines. As technology has advanced, portable ultrasound equipment, including handheld ultrasound systems, have emerged in the field of medical imaging. However, these devices may have limited imaging capabilities and reduced image quality compared to larger systems.
Types of ultrasound systems compiled according to their portability:

In summary, pros and cons of portable ultrasound machines:

Ultrasound machines, with their various components and types, have revolutionized the field of medical imaging. These devices enable healthcare professionals to visualize internal structures, assess conditions, and guide interventions with real-time imaging capabilities. Today, medical ultrasound systems are complex signal processing machines. Assessing the performance of an ultrasound system requires understanding the relationships between the characteristics of the system, such as the point spread function, temporal resolution, and the quality of images. Image quality aspects include the detail resolution, contrast resolution and penetration. Systems with microbubble scanner modification are particularly suitable for contrast enhanced ultrasound.


In summary, ultrasound machines have diverse performance levels and corresponding price ranges, catering to various medical imaging needs. From low-performance systems with basic imaging capabilities to high-performance and premium systems with advanced features, ultrasound technology continues to advance healthcare imaging capabilities.

Equipment Preparation is an essential step in ensuring optimal ultrasound imaging quality and maintaining a safe and hygienic scanning environment. The following considerations should be taken into account:

By following these equipment preparation guidelines, healthcare professionals can ensure accurate and safe ultrasound examinations while promoting infection control measures and maintaining a hygienic environment for both patients and staff.

Handheld ultrasound systems are portable devices for smartphone or tablet and are increasingly common in emergency, intensive care and veterinary medicine, but also in the pocket of the stationary doctor. This type of ultrasound machine enables immediate diagnoses directly on site (handheld point-of-care-ultrasound / HPOCUS) and quickly provide information regarding the patient's further care. Handheld ultrasound machines fit into a single-use plastic cover and can be easily disinfected, making them particularly useful in infectious environments.
The most striking advantage of handheld POCUS devices is the small footprint. The design is very compact, lightweight (approx. 200 g/0,44 lbs. - 500 g/1,1 lbs) and flexible. Due to this compactness and the necessary technical compression, the quality of the imaging is still limited compared to 'high-end devices', but sufficient to the extent that handheld ultrasound devices are already successfully used in many medical disciplines.
Depending on the model, handheld ultrasound systems run on Android, iOS, Windows or proprietary operating systems. They are connected to the end device via USB cable or wirelessly via Bluetooth or WiFi. The respective end device is used as an ultrasound monitor to display the ultrasound images. The associated app is operated via touchscreen, although some devices have a few buttons, e.g. for recording ultrasound images or freeze images. The images can be stored and managed on the end device itself, the inserted memory card or in the cloud. Theoretically, also a private smartphone can be connected, but this can lead to complications with reimbursement.
