Blue lasers offer three times the storage capacity of DVDs
Blue lasers have a shorter wavelength than traditionally used red lasers, allowing more data to be stored in smaller spaces. Two companies promoting blue laser technology at the RSNA meeting are presenting similar claims and products.
Blue lasers have a shorter wavelength than traditionally used red lasers, allowing more data to be stored in smaller spaces. Two companies promoting blue laser technology at the RSNA meeting are presenting similar claims and products.
Plasmon claims its ultradensity optical technology can store 30 GB on a single cartridge, three times the capacity of DVD and magneto-optical media. Sony claims it can pack 23 GB on a single-sided disc with a technology that boasts 11-MB/second-read and 9-MB/second-write speeds.
Sony has developed three models: an internal SCSI, an external SCSI, and an external USB 2.0 version. They read data at 11 MB/sec and write data at 9 MB/sec.
Both companies featured products based on blue laser technology in the context of plans to develop subsequent generations that might store beyond 100 GB on double-sided media. They expect this capacity within several years.
Plasmon plans to double storage capacity at least every 18 months, reaching 120 GB within three years. This continued development will make ultradensity optical technology ever more appealing.
MRI Long Covid Study Reveals Link Between Lower Pulmonary Gas Exchange and Cognitive Dysfunction
November 26th 2024For patients with Long Covid, lower pulmonary gas exchange may be associated with lower gray and white matter volume, according to new MRI research to be presented at the Radiological Society of North America (RSNA) conference.
The Reading Room: Artificial Intelligence: What RSNA 2020 Offered, and What 2021 Could Bring
December 5th 2020Nina Kottler, M.D., chief medical officer of AI at Radiology Partners, discusses, during RSNA 2020, what new developments the annual meeting provided about these technologies, sessions to access, and what to expect in the coming year.
AI Facilitates Nearly 83 Percent Improvement in Turnaround Time for Fracture X-Rays
December 19th 2023In addition to offering a 98.5 percent sensitivity rate in diagnosing fractures on X-ray, an emerging artificial intelligence (AI) software reportedly helped reduce mean turnaround time on X-ray fracture diagnosis from 48 hours to 8.3 hours, according to new research presented at the Radiological Society of North America (RSNA) conference.
RSNA 2020: Addressing Healthcare Disparities and Access to Care
December 4th 2020Rich Heller, M.D., with Radiology Partners, and Lucy Spalluto, M.D., with Vanderbilt University School of Medicine, discuss the highlights of their RSNA 2020 session on health disparities, focusing on the underlying factors and challenges radiologists face to providing greater access to care.
Can an Emerging PET Radiotracer Enhance Detection of Prostate Cancer Recurrence?
December 14th 2023The use of 68Ga-RM2 PET/MRI demonstrated a 35 percent higher sensitivity rate than MRI alone for the diagnosis of biochemical recurrence of prostate cancer, according to research recently presented at the Radiological Society of North America (RSNA) conference.
Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases
December 7th 2023Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.
