SYSTEMS AND METHODS FOR DETERMINING CORRECTION PARAMETERS FOR IMAGING DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18674977 titled 'SYSTEMS AND METHODS FOR DETERMINING CORRECTION PARAMETERS FOR IMAGING DEVICES
Simplified Explanation: The patent application describes systems and methods for determining correction parameters for a Positron Emission Tomography (PET) scanner with multiple detector units based on scan data of a phantom at various positions.
- The methods involve determining coincidence events on each line of response associated with the detector units.
- Correction parameters are then calculated based on the coincidence events to improve the accuracy of the PET scanner.
Key Features and Innovation:
- Determining correction parameters for a PET scanner with multiple detector units.
- Analyzing scan data of a phantom at different positions to calculate coincidence events.
- Improving the accuracy of the PET scanner by adjusting correction parameters for each line of response.
Potential Applications: The technology can be used in medical imaging facilities, research institutions, and hospitals for more precise PET scans.
Problems Solved:
- Enhancing the accuracy of PET scanners with multiple detector units.
- Improving the quality of imaging results in PET scans.
Benefits:
- Increased accuracy in PET imaging.
- Enhanced diagnostic capabilities.
- Better patient outcomes.
Commercial Applications: The technology could be valuable for medical device manufacturers, healthcare providers, and imaging centers looking to offer advanced PET scanning services.
Prior Art: Prior research in the field of PET imaging and correction techniques for scanner inaccuracies may provide relevant background information.
Frequently Updated Research: Ongoing studies in the field of medical imaging and PET technology may offer new insights into improving scanner accuracy and image quality.
Questions about PET Scanner Correction Parameters: 1. How do correction parameters impact the accuracy of PET scans? 2. What are the potential challenges in implementing correction parameters in PET scanners?
Original Abstract Submitted
Systems and methods for determining at least one correction parameter for a Positron Emission Tomography (PET) scanner including a plurality of detector units is provided. For each line of response (LOR) of a plurality of lines of response (LORs) associated with the plurality of detector units, the methods may include determining, based on scan data of one or more scans of a phantom at a plurality of positions, a first sum of coincidence events on the LOR, wherein the phantom is moved to the plurality of positions along an axis of a field of view of the PET scanner during the one or more scans, and a length of the phantom is less than a length of the field of view of the PET scanner along the axis; determining, based on the first sum of coincidence events, at least one correction parameter associated with the LOR.
