Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • The standard Hounsfield unit scale in computed tomography (CT) densitometry lacks sufficient representativity for accurate tissue characterization.
  • Existing CT densitometry methods face challenges in consistent and reliable measurements.

Purpose of the Study:

  • To introduce a novel, standardized densitometric scale for computed tomography (CT) to overcome the limitations of the Hounsfield unit scale.
  • To propose a new phantom-based calibration method for enhancing CT densitometry accuracy.

Main Methods:

  • Development of a specialized phantom containing various calcium chloride solutions.
  • Utilizing the phantom to establish a new, more representative CT densitometric scale.
  • Testing and validation of CT scanner performance using the developed phantom.

Main Results:

  • The new scale, based on calcium chloride solutions, effectively eliminates the shortcomings associated with the common Hounsfield unit scale.
  • The proposed phantom provides a reliable method for assessing CT scanner accuracy.
  • Specific indications for utilizing the phantom in CT scanner testing are outlined.

Conclusions:

  • A novel CT densitometry scale offers superior representativity compared to the conventional Hounsfield unit scale.
  • The calcium chloride phantom-based method provides a standardized solution for CT densitometry problems.
  • The developed phantom serves as a valuable tool for routine CT scanner quality assurance.
