Abstract [en]

Digital image processing in terms of image restoration and noise reduction assumes a thorough knowledge of the gamma camera transfer function in any clinical measurement. A phantom is designed which can simulate a slice of activity through an organ and hence can be used to determine the corresponding transfer function. The advantage of this phantom compared to an ordinary line source is that the organ thickness can easily be simulated and calculations of an effective depth of an organ and the corresponding attenuation coefficient are not necessary. On the other hand the phantom can be used to determine the depth at which a line source should be positioned for measurement of a certain clinical situation.
