Half Value Layer Attenuator Set - Gammex 115A
|
|
Determining the Half Value Layer (HVL) of the x-ray beam is the Standard method for specifying the quality of the x-ray beam. For a given kVp, a measurement of the HVL gives information on the total filtration in the x-ray beam. Too little filtration results in unnecessary radiation to the patient and too high of a HVL may require increased kVp and mAs, increasing tube loading and reducing tube life.
|
|
|
Half Value Layer Attenuator Set - Gammex 115H
|
|
While the aluminum supplied in the 115A (above) is appropriate for testing non-mammographic systems, it is insufficiently pure for accurate testing of mammographic systems. The Gammex 115H Half Value Layer Attenuator Set provides the needed substrate purity for accurate MQSA HVL compliance. The set consists of six 10x10x0.1 mm sheets of 99.99% pure aluminum, and includes a plastic storage case to protect and help maintain flatness of the filters.

|
Pure Copper Half Value Layer Attenuator Set - Gammex 116
|
|
Regulatory test
protocols for fluoroscopic systems increasingly specify copper attenuators to simulate heavier patients. When doing these tests, it is often useful to apply additional copper to drive the systems to maximum output. Copper filters are still used for specifying the Half Value Layer (HVL) of x-ray beams generated between 140 and 400 kVp. The Gammex 116 Pure Copper Half Value Layer Attenuator Set is comprised of nine sheets, 10x10 cm in thicknesses ranging from 0.1mm to 2.0mm. A plastic storage case is provided to protect and to help maintain flatness of the filters. |

Radiographic Aluminium Stepwedge - Gammex 117
|
|
The aluminum stepwedge is the standard tool for evaluating the dynamic range (latitude) of a digital or film-screen imaging system. This wedge provides 11 steps in 3.2 mm increments. The number of distinguishable steps represents the dynamic range of the system. Images may be evaluated visually or by using a densitometer. The Gammex 117 Stepwedge provides a useful means of comparing the characteristic curve of various film/screen combinations, mAs reciprocity, and if done very carefully, sensitometry.

Gammex 141/141H High Contrast Resolution Test Tools
|
|
An important measure of your fluoroscopy system is its high contrast resolution. This test is used to assess the resolving power of your system and can be done easily with the Gammex 141 and 141H High Contrast Resolution Test Tools. The difference between the 141 and the 141H is the mesh. The 141 is used for standard radiographic systems with resolutions between 16 and 60 mesh. The 141H is designed and recommended for systems with high resolution such as those used in cardiology suites, where resolution is between 60 and 150 mesh.

Neonatal Chest Phantom Gammex 610
|
|
The Gammex 610 Neonatal Chest Phantom is designed for routine quality assurance monitoring of computed and digital radiography systems. The 610 phantom replicates both the anatomic structure and the tissue attenuation characteristics of a real neonate, therefore it can be imaged using clinical protocols resulting in a test of the entire imaging chain, including image processing parameters. The Gammex 610 is the first anthropomorphic neonatal phantom that sufficiently represents a 1-2 kg neonate in its transmission characteristics, histogram, physical size and structure. As such, it can be imaged using the appropriate clinical parameters to provide a measure of image consistency over time.
