Summary
A new wireless Picture Archiving and Communication System (PACS) device significantly reduces image transfer time from portable imaging devices. This wireless PACS technology improves workflow and enables faster patient treatment.
Area of Science:
- Medical Imaging
- Health Informatics
- Wireless Communication Technology
Background:
- Traditional Picture Archiving and Communication Systems (PACS) face challenges with image transfer from portable imaging modalities.
- Efficient image transfer is crucial for timely diagnosis and patient care, especially with mobile diagnostic equipment.
Purpose of the Study:
- To develop a wireless PACS device integrated with portable imaging modalities.
- To analyze the impact of this wireless PACS device on image transfer time and workflow efficiency.
Main Methods:
- A laptop with wireless local area network (LAN) capabilities was configured as a wireless PACS device with DICOM modules.
- The device was attached to portable imaging machines (e.g., ultrasound) for image transfer.
- Image acquisition-to-storage time intervals were compared between examinations using the wireless PACS device (n=62) and those without (n=50).
Main Results:
- The mean time interval for image transfer to the PACS server was significantly reduced with the wireless device (342.4 s) compared to the traditional method (2,305.5 s).
- Statistical analysis (t-test) confirmed a significant difference (p < 0.001) in time intervals between the two groups.
- The wireless LAN-based PACS demonstrated a substantial improvement in reducing storage delays.
Conclusions:
- The developed wireless PACS device effectively reduces image storage intervals from portable imaging examinations.
- This technology enhances workflow efficiency, potentially leading to more rapid patient treatment and improved healthcare outcomes.
