Summary
A new direct data link connects CT scanners to radiation treatment planning systems. This system enables rapid, error-checked transfer of CT scan data for improved radiotherapy workflows.
Area of Science:
- Medical Physics
- Radiotherapy Technology
- Biomedical Engineering
Background:
- Accurate patient imaging is crucial for effective radiation therapy planning.
- Efficient data transfer between imaging and planning systems can streamline radiotherapy workflows.
Purpose of the Study:
- To develop and evaluate a direct data link for transferring CT scan data to a radiation treatment planning system.
- To improve the speed and reliability of data transfer in radiotherapy.
Main Methods:
- Developed a direct serial data link using coaxial cable and pseudo-paper-tape punch and reader (serial PIO) interfaces.
- Implemented error-checking protocols for data integrity.
- Measured data transmission rates and transfer times for CT scans.
Main Results:
- Achieved a data transmission rate of approximately 25,000 8-bit bytes/s with error-checking.
- Successfully transferred a CT scan (320-pixel diameter) in approximately 7 seconds.
Conclusions:
- The developed direct data link provides a fast and reliable method for transferring CT scan data.
- This technology can significantly enhance the efficiency of radiation treatment planning processes.
