Kalkulator Volume Tiroid (Thyroid Volume Calculator)

Ellipsoid Method: Volume of one lobe = 0.523 × Width × Depth × Length
Brunn Method(WHO): Volume of one lobe = 0.479 × Width × Depth × Length
Ellipsoid(Heywood): Volume of one lobe = (π/6) × R × R × Length = (2/3) × S × Length
* 0.523 ≈ π/6, R(cm) = 2 × √(S/π), S(cm²) = Area of th Thyroid ROI
※ Secara umum, Ellipsoid Method paling banyak digunakan dalam praktik klinis.

*Width : Lebar kiri-kanan lobus tiroid (Transverse plane)
*Depth : Ketebalan anterior-posterior[A-P] lobus tiroid (Transverse or Longitudinal plane)
*Length : Panjang longitudinal lobus tiroid (Longitudinal plane)

(1) Rt. Thyroid Lobe

Lebar [Width] (cm) :
Ketebalan [Depth] (cm) :
Panjang [Length] (cm) :
ROI [Opsional] (cm²) :

(2) Lt. Thyroid Lobe

Lebar [Width] (cm) :
Ketebalan [Depth] (cm) :
Panjang [Length] (cm) :
ROI [Opsional] (cm²) :
*Jika nilai ROI dan Length tersedia, Ellipsoid(Heywood) Volume juga akan dihitung.

※ Volume tiroid normal pada orang dewasa: sekitar 15 ~ 20mL
