Low-cost telesonography connects remote clinics
Researchers from Dartmouth Medical School established a low-cost telesonography model with real-time transmission over low-bandwidth connections between a remote clinic in an underdeveloped area and their facility.
Researchers from Dartmouth Medical School established a low-cost telesonography model with real-time transmission over low-bandwidth connections between a remote clinic in an underdeveloped area and their facility (AJR 2007;188[3]:W219-W22).
The research by Dr. Veljko Popov and colleagues was facilitated by recent technological advancements in the availability of inexpensive compact sonographic devices, low-bandwidth Internet connections via terrestrial or satellite links, and inexpensive hardware and software solutions for transmission of sonography data in teleconference settings.
Teleconferencing applications based on the H.323 protocol, a recommendation from the International Telecommunication Union that is being used in Voice-over-IP (VoIP)- and Internet Protocol (IP)-based videoconferencing, are capable of transmitting video and audio streams in real-time, transferring files, and allowing remote access and control of computers "By combining real-time video streams and still image capture, the bandwidth requirements decrease substantially, and image transmission over telephone lines or satellite link becomes possible," Popov said.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
