Pro-NM Performance ECT
[ click the picture ]
Phantom for NM systems performance evaluation: routine quality assurance tests, as well as extensive acceptance tests. It can be used to evaluate: pixel size, spatial linearity, RMS noise, signal to noise ratio (SNR), slice width, uniformity, spatial resolution, point spread function, slice position verification, slice incrementation, accuracy, center of rotation, verification, volume sensitivity and low contrast sensitivity.
Technical data (can be modified to customer specifications):
- main cylinder:
– internal cylinder diameter: 206mm – internal cylinder height: 186mm
– cylinder wall thickness: 7mm - main insert (slice width, pixel size and high resolution):
– external diameter 200mm
– free square internal 80x80mm
– consists of 10x 5mm discs, 2 spacers and 3 mounting screws
– contains a pair of channels 20 x 10mm thick forming two hot ramps whose slope angle tangent is equal to 0.5
– contains four hot holes 5mm in diameter that are located in corners of the 120x120mm square
– contains four groups of hot and cold resolution patterns that are 2, 4, 6 and 8mm thick and correspond to 2.5, 1.25, 0.83 and 0.625 LP/cm - point source insert (PSF - point spread function):
– the fill plug can be positioned at the center or at radial plug location
– source screw contains a well (Ø 3 x 5mm) that can be filled with appropriate solution
– source screw can be mounted outside of or inside the phantom (for in air or scatter measurements) - low contrast inserts:
– can be threaded into the phantom in a radial pattern 75mm of the center axis
– three cold low contrast rods comprised of three parts: 10, 15 and 20mm in diameter and 40mm long
– three optional hot low contrast rods comprised of three parts: 10, 15 and 20mm in diameter and 40mm long that can be filled from the outside - heavy duty carrying case
