Approaches to Dose Reduction in Urology

Dose Reduction Advances in Urology

The comprehensive CARE dose reduction program with the ability to combine several applications enables reduction in dose without compromising image quality.



Accurate localization and monitoring of the stone during ESWL (extracorporeal shock wave lithotripsy) procedures is key. This can be performed by low-dose fluoroscopy or completely radiation-free, with ultrasound. With both methods available on Siemens systems, the choice can be made based on the clinical situation and the right dose.

Endourology and Urodiagnostics

The flat-detector-based urology system UROSKOP Omnia offers excellent dose-saving features.

In the past, using an image intensifier technique, the urologist had to acquire two and more images in order to cover the entire urinary tract (KUB = kidneys, ureters, bladder). Now, thanks to the 43 cm x 43 cm dynamic flat detector and the large field of view, only one exposure is needed to receive a full KUB image.

Compared to conventional cassette exposure technique the dose required can be significantly reduced with flat panel technology without compromising image quality. For the many daily standard cases such as documentation of a DJ stent, even more dose can be saved by using DFR exposures.

Patient Skin Dose Measurement at UROSKOP Omnia

  • Simulation of patient thickness with polymethyl methacrylate (PMMA)
  • Collimator format 30 cm x 30 cm
  • FFD 115 cm; FTD 108 cm
  • Dose measurement with Unfors XI (patient skin dose)
