An ultrasonic diagnosticator is a device that utilizes ultrasound to measure or acquire images of soft tissue or blood flow. They are mechanical waves whose frequency exceeds that of the audible spectrum.
The ultrasound system is equipped with a probe consisting of a matrix of piezoelectric elements to generate the ultrasound beam. Ultrasound beams diffuse and reflect in different tissues and fluids. The organs differ and the reflections of the ultrasound are more or less different. The main purpose of processing this wave is to measure the structure or form an image that can be used for diagnosis.
How to choose an ultrasonic diagnostic instrument?
Budget should certainly be considered when choosing a diagnostic ultrasound, but it is also important to consider the intended application. These factors will influence our choice.
First, it is necessary to consider the main imaging modalities that currently exist
Type B (luminance) ultrasound system;
M-mode ultrasound system;
Color Doppler imaging to explore blood flow in arteries and veins;
Ultrasound elastography technique measures the stiffness of tissues.
Then, the size and weight of the equipment must be considered
Size and weight of the ultrasonic diagnosticator: whether portable, on platform, or handheld: the now available ultrasonic diagnosticators can be easily transmitted from one unit to another in the hospital. Many hand-held (handheld) models weigh as little as 500 g and can be easily placed in pockets or packs; Some can connect wirelessly to a smartphone. Therefore, they are very useful for first aid and site directed medical treatment.
It is also important to take into account the size of the screen and the quality of the images. Some portable ultrasonic diagnosticators can display up to 250 gray levels, while others are equipped with color screens. Brightness is also an important factor to consider, especially when you need to use an ultrasound system outdoors, such as the environment in which it is used by a veterinarian. Brightness must be adjusted without compromising the readability of the detection results.
Type and number of probes (shape, frequency, etc.). The type of probe you choose will depend on what you do. Nowadays there are all in one probes that can transform smartphones or tablets into ultrasound systems. These are based on downloadable applications and one or more microprobes (surface, abdominal, cardiac, etc.) connected to a mobile phone or tablet via a simple USB port. You can then view the results directly on the device. This type of equipment is appropriate for emergency physicians as well as sports or humanitarian.
Battery life is another parameter to consider, especially when choosing portable or hand-held ultrasound systems. For this type of device, the battery life span is best achieved in the order of a few hours.
