DIAGNOSTIC IMAGING QA

In addition to our core solutions, Gammex provides a range of additional products to support your radiology workflows.



Collimator and Beam Alignment QC Tools

Evaluate collimator light field and x-ray field congruence, and ensure accurate x-ray beam alignment.


  • Designed according to Center of Devices and Radiological Health (CDRH) specifications
  • Available in two models to meet your needs


The Collimator Alignment QC Tool is constructed of brass so centimeter etchings on its surface can provide a direct ruled dimension on the radiograph with a normal x-ray exposure. 


The Beam Alignment QC Tool provides a simple test ofalignment for x-ray beams. When used with the Collimator Test Tool, x-ray beam misalignments of 1% and 2% can be visualized without the need for measuring or calculating. 


The Beam Alignment QC test instrument is constructed of a plastic cylinder high with two steel BBs, one at each end. The steel BBs are located directly above one another so that, when level and in alignment, they will be superimposed on the radiograph. A bubble level is included so accurate tests can be performed quickly and with ease.

High Purity Aluminum HVL Set

Comply with regulatory requirements for QA testing of radiographic and fluoroscopic systems.

  • Achieve low contrast readings within 2%
  • Help make the right diagnosis for your patients


The LC Resolution QC Tool (model 151) provides the resources needed to comply with low contrast and output response requirements. Components can be used to test performance aspects of both digital and analog spot-film devices, radiographic automatic exposure control functions, and digital angiography and digital cine-angiography.


With the LC Resolution QC Tool, you gain the versatility to measure the automatic brightness stabilizer, maximum entrance exposure at the tabletop, and photo-timer performance of the spot film device – all using a single tool. This flexible tool can achieve accurate low contrast readings within 2%, helping ensure that your fluoroscopic system is working at its optimal efficiency and effectiveness.

Contrast Detail QC Tool

Determine threshold contrast characteristics and monitor performance.


  • Use with radiographic and fluoroscopic systems
  • Test the full range of your equipment


The Contrast Detail QC Tool (model 1151) is an aluminum plate with a 10 x 10 matrix of circular indents designed to test the full range of your imaging equipment. All of the contrast indents in a given row have a constant depth. All of the indents in a given column have a constant diameter providing a total 100 contrast combinations. Contrast-detail curves can be constructed by observing the shallowest depth hole that can be seen for each indent diameter.


  • 100 contrast combinations are available
  • All contrast indents in a given row have a constant depth
  • All indents in a given column have a constant diameter
  • Contrast-detail curves can be constructed by observing the shallowest depth hole that can be seen for each indent diameter
