The performance of the probe directly affects the characteristics of the ultrasound wave, affecting the imaging effect. Different probes are applicable to different parts, find out more.
1、 Line array probe
Features: the probe surface is flat, the contact surface is large, the imaging field of view is rectangular, the imaging resolution is high, the penetrating power is relatively low, suitable for superficial blood vessels, small organs, muscles and bones and other examinations.
2、 Phased array probe
Features: the probe surface is flat, the contact surface is small, can be in the intercostal scanning near-field field of view is the smallest, far-field field of view is large, the imaging field of view is fan-shaped, applicable to the heart.
3、 Convex array probe
Features: The probe surface is convex, the imaging field of view is fan-shaped, the far field of view is large, due to the relatively low frequency so the penetration is relatively high. Widely used, often used in the abdomen, gynecology and obstetrics and other relative parts of the deeper organs.
4、 Volume probe
On the basis of two-dimensional images, the spatial distribution of the position of the continuous acquisition, through the computer reconstruction algorithm, so as to obtain a complete spatial form.
Applicable to: Fetal Face, Spine and Limbs, etc.
Advantageous features: rapid acquisition, continuous and uniform sweep, anatomical structure displayed as volumetric data, accurate volumetric measurement.
5、 Intracavitary probe
Features: high frequency, high image resolution, no need to fill the bladder, the probe is close to the examined area, so that the pelvic organs are in the near-field area of the acoustic beam, and the image is clearer.
