Dosimetry with and without chest phantom radiation shields and thorax phantom - examination of noise and average CT number in the CT scan phantom CTDI image with and without radiation shields - examination of artifacts in the chest CT scan image of female patients without and with the best shield.
Conditions
Interventions
Intervention 1: Intervention group: 30 female patients aged 20-75 years, on whom we put the best radiation shield (suitable dose reduction and minimal noise on the image) during lung CT. Intervention

| Investigating noise and average CT number in CTDI phantom CT image with and without radiation protection. Timepoint: During 1months. Method of measurement: Using DICOM files software.;Chest and thorax phantom dosimetry with and without radiation shields. Timepoint: 2 months. Method of measurement: Using TLD dosimeter and RTI Piranha dosimeter.;Artifact examination in lung CT images of female patients without radiation protection and with the best protection (in terms of reducing the dose and creating the least noise on the image) is placed on their chest. Timepoint: 3 months. Method of measurement: Review of images by an experienced radiologist. | — |
