Advanced CT Performance Assessment.

Now it's easy to characterize advanced CT features that fall outside of your routine QA program. Like Automatic Exposure Control. And Iterative Reconstruction. Plus, you can revamp your traditional tests with new metrics that enable robust and quantitative evaluation.

High-Contrast Resolution Module


Image

The High Resolution Module enhances testing of high image frequencies by providing test patterns ranging from 2 to 32 lp/cm. The patterns are created with a patent pending technique that allows larger pattern dimensions, providing for easier visualization and more accurate automation. It can be used as a standalone, or modularly expand the 464. This product includes a 5-year warranty.

Low-Contrast Detectability Module


Image

The Low Contrast Detectability Module enhances testing of low contrast detectability by using 3 precise contrast levels, and sizes at each contrast level ranging from 1.5 mm to 25 mm. There are multiple objects at each size and contrast (except 25 mm) for robustness vs noise and to test radial dependence. The LCD module can be used as a standalone, or modularly expand the 464. This product includes a 5-year warranty.

Slice Sensitivity and Geometric Evaluation Module


Image

The Slice Sensitivity and Geometric Evaluation Module includes a number of tools to enhance CT image quality testing. It features a pair of wire ramps for slice thickness, 2 pairs of bead ramps, BBs for MTF, acrylic spheres for geometric accuracy, and an off-vertical wire for MTF. It can be used as a standalone, or modularly expand the 464. This product includes a 5-year warranty

Uniformity Module


Image

The Uniformity Image Quality Module can be used for measurements of noise and uniformity, as well as for metrics like MTF, NPS. It includes 2 BBs for measurement of distance and pixel size. The Uniformity Module can be used in conjunction with other image quality modules and/or the 464 ACR CT Phantom. The Uniformity Module can also function as an extension plate for CT and CBCT system with wide-angle detectors. This product includes a 5-year warranty.

CT Electron Density Phantom

Image

This electron density phantom is used to provide accurate corrections for tissue inhomogeneities and to establish the relationship between the electron density of various tissues and their corresponding CT numbers. The Phantom consists of a Solid Water disk approximately the size of an average pelvis with 16 ports for interchangeable density inserts. It also includes 16 density rods representing a range of tissues. Also includes carrying case. This product includes a 5-year warranty.

CTDI Phantoms - 3 Piece


Image

The Gammex CTDI 3-Piece Phantom easily measures absorbed dose and monitors scanner output faster and more easily than ever before. The tongue and groove design provides precise, fast module and insert placement. The 3-pieces can be used together to simulate adult head and body, or the 2 inner pieces can be used to simulate pediatric head and body. Includes a custom water-tight, hard case, and wedges for stabilizing the phantom on the couch. This product includes a 5-year warranty.

Solid Water HE Slabs


Image

Solid Water HE is the next generation of water-mimicking material pioneered by Gammex. Our patented technology more accurately mimics true water within 0.5% for therapeutic and diagnostic energies. Enhanced uniformity and reduced variation compared to other water-mimicking formulations, more consistent and accurate results. Includes unique Nanosphere technology that provides high strength and water equivalence. Slabs are available at varying thicknesses: 1 at 0.1 cm, 2 at 0.3 cm, 1 at 0.5 cm, and 29 at 1.0 cm. All of the Solid Water HE Slabs include a 5-year warranty.

CT Perfusion Phantom


Image

The CT Perfusion Phantom is designed to mimic the injection of a contrast bolus into a region of interest allowing you to generate precise time-attenuation curves (TAC), of differing velocities, to better monitor your CT Perfusion program, and patients. Once you benchmark perfusion rates and TACs for each system using the phantom, you will be better positioned to know if future measurements show a true change, or if follow-up results are within the precision error of the measurements. Use the dose port to optimize imaging and perfusion protocols and results at the lowest possible dose.
