The new Advanced Electron Density Phantom is 16.5 centimeters thick for use with wide-beam, cone-beam or multi-slice CT scanners with 16.5-centimeter-thick rods, which resemble human body tissue.

It is important the tissue mimicking materials extend the full length of the phantom and the rods are constructed of solid materials and not just a smaller core of material, said Kenneth Ruchala, product manager for Gammex. This allows for a larger sample size when analyzing the tissue densities.
The rod materials are benchmarked against the ICRU-44 and ICRP standards for materials that represent human tissue, Ruchala said.
"We've used reagents that we think are very reliable and robust, providing a consistent match to the standards," Ruchala said.
The rods also come with patent-pending markers that identify the material it is supposed to resemble, which Ruchala said makes the identification process faster. The markers, used with software that is planned to be released this summer, can streamline the process of analyzing scan data to create the tissue density calibration.
Previously, a tester would have to use a photograph match to determine content of the rod and then manually find out the average value and density, Ruchala said, noting that automation would make the process less prone to error.
"I think it will let clinics use their staff time more efficiently," Ruchala said.
Netech
In June 2018, Netech launched the Delta 3300, a compact and lightweight defibrillator/transcutaneous pacemaker analyzer that can measure both monophasic and biphasic waveforms. It also has a 12-Lead ECG/arrhythmia simulator function, with data saving and printing capabilities.
“Delta 3300 is the most user friendly and smallest defibrillator analyzer in the market today,” said Wijin Joe Oommen, sales manager for Netech Corporation. “With its lithium ion rechargeable battery, the device is portable and ideal for on-the-go testing."
