PROBE FREQUENCIES AND APPLICATIONS
  • Applications of the ultrasound probes are categorized based on their center frequency.
  • Probes with higher frequencies have shorter wave length and are attenuated easily.
  • For high penetration the frequency must be less.
  • Higher frequency probes are used for scanning of superficial body structure.
  • Lower frequency probes are used for scanning of deeper body parts.
PROBE FREQUENCY AND APPLICATIONS
1. 2.5 MHz
  • Eg:- GE RAB2-5L
  • Used for deep abdomen
  • Obstetrics and gynecological application
2. 3.5 MHz
  • Eg:- GE 3.5C
  • General abdomen
  • Obstetrics and gynecological application.
3. 5MHz
  • Eg:- Philips  S5-1
  • Vascular
  • Infant cardiac applications
4. 7.5 MHz
  • Eg:- GE L40
  • Breast Scanning
  • Thyroid
5. 10MHz
  • Breast
  • Thyroid
  • Musculoskelton imaging
  • Superficial masses
  • Superficial veins
6. 15MHz
  • Eg:- GE ML6-15 D
  • Superficial structures
  • Musculoskelton imaging
