Introduction: Recent studies of Computed Tomography (CT) conducted on patient dose reduction have recommended using an iterative reconstruction algorithm and mA (mili-Ampere) dose modulation. The current study aimed to evaluate Iterative Dose Reduction Algorithm (IDREAM) as an iterative reconstruction algorithm. Material and Methods: Two CT p...

Background: The present study intended to determine and report patient effective dose on the basis of patients and exposure data. Materials and methods: A nationwide computed tomography (CT) survey was provided as a report of patient doses in 2015-2016. Scan details were collected for nearly 2,000 adults and children in four age groups subjected to CT examinations. From total 565 CT scanners in...

Telah dilakukan penelitian tentang penentuan besar dosis pasien pada Computed Tomography (CT) Scan kepala dengan metode Size Specific Dose Estimate (SSDE) dan faktor risiko terjadinya katarak. Nilai SSDE diperoleh dari data nilai Index Volume (CTDIvol), Anterior Posterior (AP) Lateral (LAT). Data 30 kelompok anak-anak usia 5-14 tahun dewasa 15-50 tahun. rata-rata untuk sebesar 52,387 mGy 49,664...

The purpose of this work was to evaluate computed tomography simulators used in radio-therapy treatment planning Serbia, Croatia, and Bosnia Herzegovina. A survey quality assurance programmes 24 16 facilities conducted. dedicated CT-to-ED phantom scanned at 120 kV 140 kV, obtain conversion curves as well CTDIvol. Thoracal phantoms were the standard extended field view dosimetric effect on deliv...

BACKGROUND To investigate the radiation dose and image quality for iterative reconstruction combined with the CARE kV technique in chest computed tomography (CT) scanning for physical examination. METHODS A total of 130 patients who underwent chest CT scanning were randomly chosen and the quality reference value was set as 80 mAs. The scanning scheme was set and the patients were randomly div...

Dosis radiasi CT Scan menyumbang 70% Total dosis yang diterima dari pencitraan medis, tinggi atau rendahnya dapat meningkatkan risiko kanker. Untuk memastikan sebanding dengan tujuan medisnya, ke pasien perlu dioptimisasi menerapkan Diagnostic Reference Level (DRL) untuk mengoptimalkan perlindungan paparan medis bagi pasien. Evaluasi pemeriksaan MSCT Thorax dan penerapan DRL belum pernah dilaku...

AMAÇ: Bu çalışmada amaç, böbrek nakli vericilerinin renal bilgisayarlı tomografi anjiyografi (RBTA) tetkiklerinin radyasyon dozunu saptamaktadır.GEREÇ VE YÖNTEM: Etik kurul onayı retrospektif olarak alınan bu çalışmaya 3. basamak hastanede Temmuz 2017 ve Aralık 2019 tarihleri arasında çekilen RBTA tetkikleri dahil edildi. Görüntü arşivleme iletişim sisteminden, BT hacimsel doz indeksi (Volume C...

In the radiological department, computed tomography (CT) scan process has become a greater radiation dosage that contributes to all medical X-ray treatments. Many studies throughout world have found CT accounts for just 5% of operations conducted yet 34% yearly exposures in Similarly, other 17% worldwide but 49% total doses Because diagnostic reference levels (DRLs) are one ways optimizing dose...
