- Description
- Specifications
The 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:
- Main cylinder:
- Internal cylinder diameter: 206 mm – internal cylinder height: 186 mm
- Cylinder wall thickness: 7 mm
- Main insert (slice width, pixel size and high resolution):
- External diameter 200 mm
- Free square internal 80 x 80 mm
- Consists of 10x 5 mm discs, 2 spacers and 3 mounting screws
- Contains a pair of channels 20 x 10 mm 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 120 x 120 mm square
- Contains four groups of hot and cold resolution patterns that are 2, 4, 6 and 8 mm 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
