Oznake: lumbar spine radiography;radiation dose reduction;radiosensitive organ;
This study aimed to investigate the different positioning of the patient in left and right lateral position during lumbar spine radiography and its effects on effective dose and absorbed dose for selected organs. The study was performed on a Siemens Multix/Vertix X-ray unit using Agfa's computer rad ...

Oznake: erect pelvic radiography;fat tissue displacement;image quality;radiation dose;
Introduction: Pelvic radiography is one of the most frequent general radiography imaging procedures. Pelvic radiography is usually performed in the supine position, but in some cases erect imaging is performed. The aim of this study was to determine whether radiation dose and image quality differ be ...

Magistrsko delo
Oznake: magistrska dela;radiološka tehnologija;CT slikanje glave;svinčena zaščita;znižanje doze;ščitenje dojk;
Uvod: Računalniška tomografija (CT) največ prispeva k izpostavljenosti pacientov ionizirajočemu sevanju. CT slikanje glave je najbolj pogosto izvajano CT slikanje, pri katerem so dojke, ki spadajo v skupino organov z najvišjo radiosenzitivnostjo, izpostavljene sipanemu sevanju, čeprav ležijo izven p ...

Oznake: mammography;mammography screening;image evaluation;image quality;subjectivity;
Introduction: According to the guidelines, the mammograms obtained in a screening program must be evaluated to ensure that the quality of the images obtained is above 75% of score 1 (perfect and good) and less than 3% of score 3 (inadequate). This is performed by a person (usually a radiographer), s ...

Oznake: scatter radiation;head CT;lead shielding;breasts;dose reduction;
Background. Female breasts are exposed to scattered radiation regardless of not being included in the primary field during head CT. This study aimed to investigate whether the use of lead shielding is beneficial in dose reduction to the breasts during head CT. Patients and methods. The study was per ...

Diplomsko delo
Oznake: diplomska dela;radiološka tehnologija;možganski tumorji;radioterapija;magnetnoresonančni simulator;kakovost magnetnoresonančnih slik;planiranje;
Primarni in sekundarni možganski tumorji so tumorji centralnega živčnega sistema. Vsako zdravljenje z obsevanjem je za bolnika načrtovano. Danes pri postopkih načrtovanja obsevanja možganskih tumorjev rutinsko uporabljamo računalniško tomografske simulatorje skupaj z magnetno resonančnimi simulatorj ...

Izvirni znanstveni članek
Oznake: antero-posterior C-spine;lateral C-spine;anti-scatter grid;digital radiography;image quality;dose reduction;
Introduction: Imaging of the cervical spine in general radiography is most frequently performed using an anti-scatter grid. The purpose of this study was to investigate the effects of a gridless setting on image quality and radiation dose during digital radiography of the anteroposterior (AP) and la ...

Magistrsko delo
Oznake: radiološka tehnologija;interventna radiologija;vstopna kožna doza;skupna doza v intervencijski referenčni točki;
Cilji: Zanimalo nas je kako pogosto in kakšne poškodbe na koži je povzročila obsevanost pacientov pri interventnih radioloških posegih z dozo v interventni referenčni točki nad 3 Gy. Metode: V raziskavi smo retrospektivno pregledali 7607 pacientov. Med njimi smo izbrali paciente, za katere je kerma ...
