How much do you know about the types of ultrasound probes?
1. Ultrasound probes can be classified from the following different aspects:
1. Classified by diagnostic location: There are ophthalmic probes, cardiac probes, abdominal probes, cranial probes, intracavitary probes and children's probes;
2. Classified by application method: There are extracorporeal probes, intracorporeal probes, and biopsy probes;
3. Classified according to the number of vibrating elements used in the transducer in the probe: there are also the unit probe and the multi-element probe;
4. Classified by beam control method: wired scanning probe, phased array probe, mechanical fan scanning probe and square array probe, etc.;
5. Classification according to the geometry of the probe: For different diagnosis, there are rectangular probes, various probes of column breaks, arc-shaped ultrasonic probes (also called convex), circular probes, etc.
Under normal circumstances, it is customary to use in work according to the classification of diagnostic parts, beam control method classification, and the collection shape classification of the probe.
2. Common B-ultrasound probes
1. Convex array probe 3.5MHz
2. Linear array probe 3.5MHz
3. High frequency linear array 7.5MHz
4. Cavity probe 6.5MHz
5. Heart probe 3.2MHz
6. Phased array probe 3.0MHz
7. Three-dimensional probe 3.5MHz
Three, animal probe
1. Micro convex probe 3.2MHz and 5.0MHz
2. Cavity probe 6.5MHz
3. Linear array probe 5.0MHz and 7.5MHz
Applicable scope of B-ultrasound probe:
Convex array probe is suitable for: abdomen, thoracic cavity, stomach, kidney, heart, women, etc.
Linear array probe is suitable for: skin surface, thyroid, chest, blood vessels, etc.
Micro convex probe is suitable for: abdomen, kidney, small animals, neonatal tissues and organs, etc.
How to distinguish and distinguish whether the B-ultrasound probe is a linear array, convex array, or slightly convex probe
The B-ultrasonic transducer (probe) is divided from the appearance: the mechanical fan sweep is similar to the convex array, both of which are cylindrical, and the linear array is rectangular; from the scanning mode: the mechanical fan sweep is driven by a micro-motor driven changing mechanism. The electroceramic performs fan-shaped motion, while the convex array and the linear array are electronic scanning, that is, scanning is realized by sequentially triggering the elements in the piezoelectric ceramic array; from the detection, the displayed image is divided into: the mechanical fan scanning and the image array are fan-shaped, The upper is small and the lower is big. The linear array is a plane of equal width; in addition, mechanical noise and micro-vibration are present when the mechanical B-ultrasound transducer is working, but the convex array and the linear array do not have these phenomena.
