Summary

Coronary angiography exposes patients and physicians to ionizing radiation. The purpose of this study is to evaluate the routine use of large field of view during image acquisition for coronary angiography. Patients with indication of diagnostic coronary angiography will be randomized for the use of either large field of view during image acquisition or medium field of view. Patients, physician and nurse radiation exposure will be measured by digital dosimeter.

Conditions

• Exposure to Ionizing Radiation
• Occupational Exposure to Radiation
• Radiation Injury

Interventions

Type	Name	Description
RADIATION	Large field of view arm	Patients will be allocated in the large field of view arm. Coronary angiography will be performed with large field of view lens (25 cm)
RADIATION	Medium field of view	Patients will be allocated in the medium field of view arm. Coronary angiography will be performed with medium field of view lens (20 cm)
