Lowering x-ray tube voltage for chest computed radiography (CR) improves image quality and reduces scatter. A voltage of 100 kV is recommended for optimal chest CR imaging, balancing image enhancement with clinical feasibility.

Area of Science:

  • Radiology
  • Medical Imaging
  • Diagnostic Imaging

Background:

  • Optimal x-ray beam quality for chest computed radiography (CR) remains undetermined.
  • Previous studies have not definitively established the ideal tube voltage for chest CR imaging.

Purpose of the Study:

  • To determine the optimal x-ray beam quality for chest CR.
  • To compare image quality between CR and screen-film (SF) radiography at various x-ray tube voltages.

Main Methods:

  • Chest CR and SF radiographs were acquired using a lung phantom and human volunteers.
  • Simulated lung opacities were imaged at varying tube voltages (e.g., 140 kV, 80 kV) with consistent patient dose.
  • Radiographic contrast and image quality of simulated opacities were evaluated by radiologists.

Main Results:

  • Lowering tube voltage from 140 kV to 80 kV increased contrast in CR images, though less than in SF images.
  • CR images acquired at lower tube voltages were rated superior by radiologists.
  • Reduced scattered radiation was observed in CR images at lower tube voltages.

Conclusions:

  • Chest CR image quality is enhanced by using lower tube voltages compared to conventional SF radiography.
  • A tube voltage of 100 kV is recommended for chest CR, considering image quality and clinical tube loading limitations.
