Correlations Between Body Weight and Size-Specific Dose Estimate on Thoracic Computed Tomography Examination [PDF]

Atom Indonesia, 2022
The dose received by a patient on CT examination is expressed in size-specific dose estimates (SSDE) which is a function of the patient diameter, x-ray attenuation, and scanner output (volume computed tomography dose index, CTDIvol). Patient diameter and

Evaluasi Indeks Massa Tubuh (IMT) sebagai Dasar Penentuan SSDE (Size-Specific Dose Estimate) pada Pemeriksaan CT Scan Abdomen

Jurnal Fisika, 2022
SSDE (Size-Specific Dose Estimate), merupakan parameter dosis CT Scan yang sudah memasukkan komponen ukuran tubuh pasien, yaitu diameter efektif (DE). SSDEDE kurang menggambarkan dosis pasien karena pengukuran DE hanya pada midslice citra. Penelitian ini

Using body mass index to estimate individualised patient radiation dose in abdominal computed tomography [PDF]

European Radiology Experimental, 2018
Background The size-specific dose estimate (SSDE) is a dose-related metrics that incorporates patient size into its calculation. It is usually derived from the volume computed tomography dose index (CTDIvol) by applying a conversion factor determined ...

Comparison of Size specific dose estimates (SSDE) and CTDIvol values in patients undergoing CT examinations of abdomen and pelvis [PDF]

Radiography Open
Introduction: Computed Tomography Dose Index volume (CTDIvol) is a measure of radiation output of the CT scanner and does not represent patient dose.
