Workflow Step

Modality

Beam Geometry & Alignment Testing

Beam Alignment Test Tool evaluates X-ray field congruence and ensures accurate X-ray beam alignment
Collimator Alignment Test Tool consists of an etched stainless steel baseplate to evaluate collimator light field congruence
Grid Alignment Test Tool tests proper grid alignment with respect to the central ray of the X-ray tube

Dose & Exposure Rate Measurements

Fluoroscopic Dose Rate and Low Contrast Resolution Test Tool Kit measures the automatic brightness stabilizer, maximum entrance exposure and the photo-timer performance. When used with the High Contrast Resolution tool, this ensures an optimized fluoroscopic system.

Beam Quality & Half-Value Layer

The Half Value Layer (HVL) Attenuator Set determines the HVL of the X-ray beam to specify the quality of the X-ray beam. Made of 1100 Alloy Aluminum (>99.00%), the set contains 9 sheets of various thicknesses ranging from 0.1 to 2.0 mm.

Image Quality (Contrast & Resolution)

Contrast Detail Tool monitors performance and determines contrast detail characteristics of radiographic and fluoroscopic systems
High Contrast Resolution Test Tool measure high contrast resolution of radiographic and fluoroscopic systems. Each tool (sold separately) includes eight patterns of copper mesh for systems with resolutions from 60 to 150 mesh and 16 to 60 mesh respectively. Mesh values are labeled with lead for easy identification.

Image Quality (Contrast & Resolution) continued

Ultra Star Test Pattern (1-360°) for determining focal spot size through observation of regions of blurring
Focal Spot Test Tool for assessing focal spot size. A range of bar patterns within an acrylic cylinder allow for the visually observed limiting resolution to be easily converted into an effective focal spot size.
Anthropomorphic Neo-Natal Chest Phantom represents the transmission characteristics, histogram, physical size and structure of a 1-2 kg neonate. Includes clinically relevant image quality challenges for resolution and noise in the form of a lung with simulated pneumothorax with pleural thickening, and a lung with simulated hyaline membrane disease.

DR QC Phantom

Allows for seven quality assurance assessments for monthly and semi-annual evaluation.

Radiography Fluoroscopy QA Phantom

Used for both initial QA assessment and routine monthly QA testing to help ensure patients are receiving the best possible X-ray examinations
