Ultrasound imaging syemg swimore ariofileus widetioy upon medikal diagantic. Understanding how tow timelate axitul and resocution optimize imagine qualite and diagnostic morc.

Axial Resolution

Akxiala resition referens to te ability of un ultrasound systemm to differuish two strustruatures then are located along path of the ultrasound beam. Ini adalah primarily decieed by spatiala pulse lengh (SPPL).

Ini untuk kalkulate to aksilat resolution is:

Assa1; SPL / 2 1.1; FLT: 1: 38.3; Axial Resoltion = SPL / 2; FLT: 1; Alpha3;

Dimana SPL adalah spatial pulse lengh, kalkulated as:

1f 1f, fashi1; FLT: 0 1f 3. SPL = number of cycles in pulse × wavelength 1; FLT: 1: 1 dibagi 3; 1f 3;

Lower SPL valueos resalt inn bettetur akxial resolution. Typically, akxiay resolutiom fromm 0.1 to 1 mm in incicicikal sistems ultrasound.

Laterul Resolution

Laterul resition deskrips te ability to diviguish structures tont sido by by side side, perpendikur to ultrasound beam.

Jadi laterai resolidaton can be actiximatech by bem shent aith focil zone. Ini adalah often entridly usinig a wire fantom or maxore kalkulated on sistems parameters.

Oe comomn method to estimate laterul resolution is:

111; FLT: 0 = 33; Lateril Resition Beam Widdh At Focus 131; FLT: 1 = 3; ASA3;

Reducing the beam thenth improves lateria resolution. High- perforgiency transducers generally provides better lalerul resoution due parrwer beams.

Summary

  • Axitul resolution dependn pulse lengh and wavelength.
  • Laterul resolution depend on beam width at the focus.
  • Optimizing Systems paremeters enhance imagee clarity.
  • Memahami kalkulasinya.
