It can be challenging to select the ideal probe because there are so many different options on the market.
Learn how to pick the right 2d ultrasound probe below, whether you want a new machine or a replacement for 2d ultrasound.
Frequency
When an electrical current is applied to materials made of ceramic crystals, these substances are known as piezoelectrics. Megahertz, or MHz, is a unit of measurement for the speed and distance at which these waves produce signals.The interactions that affect a transducer's frequency go beyond only speed and distance. 2d ultrasound sound waves are impacted by reflection, refraction, scatter, attenuation, and a patient's anatomy.
The required clinical application greatly depends on the frequency range, which also has an impact on image quality. Images with a better resolution are produced by probes that have a higher frequency, between 7 and 20 MHz. In contrast, smaller range (2 to 5MHz) arrays will result in lower resolution but better deep penetration.
Kind of array
The array is crucial for both image quality and choosing the right kind of probe for a given clinical situation.There are four main forms for arrays. These are the most well-liked (although there are more). Each array format yields a certain kind of data.
Sharp, high-resolution images will be produced via a linear array. Along with muscular-skeletal assessments, it is utilised for vascular, breast, thyroid, and little part examinations.The majority of applications for a micro-curved array are in the field of women's health such as OB/GYN, prostate, etc.
A phased array is an array with many stacks or levels with a tiny footprint. It is employed for several transcranial tests as well as cardiac and deep abdominal exams.
An array with a large element count is curved or convex (192 to 6000 elements). Their main areas of use are for general, OB, and abdominal 2d 2d ultrasound applications.
Medical application
Knowing the clinical application you intend to execute is another suggestion for selecting the right 2d ultrasound.Probes are created to work with the particular clinical application. The form or shape of the array and other aspects of the probe design are also determined by it.
High-frequency operation is used by linear probes. This enables higher quality photos and improved surface imaging.
Uses: Breast, MSK, Intra-lumen, Vein, and Vascular.While operating at mid-range frequencies, curved and micro-curved probes nevertheless provide high-resolution pictures. Prostate, abdomen, 3D/4D, OB/GYN, and more uses.
Low frequencies are used by phased probes. Lower resolution is achieved, but deeper penetration is made uses: deep aorta, TCD, and cardiac
Compatibility
Be sure a probe is compatible with the device you plan to use it with before you buy it. It's possible that newer transducer types won't work with older, out-of-date equipment, and vice versa. The manufacturer may occasionally be asked for an Option code.
