Area of Science:

Medical Imaging Physics
Nuclear Medicine Technology
Quality Control in Medical Devices

Background:

Hybrid PET/CT and SPECT/CT systems are crucial for accurate medical diagnoses.
Ensuring precise image fusion and alignment is vital for diagnostic accuracy in hybrid imaging.
Existing quality control methods may lack vendor independence or simplicity.

Purpose of the Study:

To evaluate the image fusion accuracy of hybrid PET/CT and SPECT/CT systems.
To introduce a novel, vendor-independent phantom for assessing image alignment.
To provide a straightforward tool for quality control in hybrid imaging.

Main Methods:

Development of a vendor-independent phantom with radioactive solution-filled channels and internal wires.
Utilizing two phantom orientations: a perpendicular cube and opposing ramps.
Scanning various vendor and model hybrid PET/CT and SPECT/CT systems.

Main Results:

The perpendicular phantom allows visual evaluation of x, y, and z registration accuracy.
The opposing ramp phantom enables verification of z-axis offsets from single axial images.
Alignment data were successfully acquired and analyzed from multiple hybrid imaging systems.

Conclusions:

The developed fusion phantom serves as a convenient, vendor-independent quality control tool.
It simplifies the evaluation of image alignment accuracy in hybrid imaging systems.
The phantom design facilitates straightforward 3D processing and visual interpretation of alignment.
