Long-length imaging is an essential radiography technique in the field of orthopedic surgery for the diagnosis of scoliosis and alignment measurements on the full length of the lower limbs. In the most hospitals, they conduct radiography with multiple IPs loaded in a long-length cassette and join the images together when reading them.
The conventional CR long-length imaging operation is complex. It requires switching the IP and reading the image after every exposure. Patient throughput is poor, as the patient has to wait in the radiography room while the images are being checked. Conversely, slot-scan radiography requires just the start and end positions to be set. Images can be checked immediately after radiography is complete, which reduces the examination time and improves efficiency.
Conventional CR long-length imaging is difficult in cases where a wide imaging field is required, such as patients with severe scoliosis and radiography of both legs simultaneously. With its 990mm MIC detector movement range and 410mm wide coverage, slot-scan DR flexibly accommodates a diverse range of radiography examinations. As many scoliosis patients are young, it is important to reduce the X-ray exposure dose over the follow-up examinations over many years. JSB's slot-scan DR exploits the wide dynamic range of the MIC detector to perform radiography with a lower X-ray exposure dose than the conventional method.
With its easy operation and excellent patient throughput, slot-scan DR could replace cassette radiography. The slot-scan DR function satisfies a range of clinical requirements and we anticipate that it will become increasingly effective for long-length imaging.
