Medicine's ability to store and share digital images and information has increased exponentially, yet the availability of critical data in medical emergencies remains dubious. Emergency physicians and surgeons frequently find themselves performing major surgery on patients for whom they have no personal medical history - often with uncertain outcomes.
A solution may be at hand, thanks to the ingenuity of four electrical and computer engineering students at Brigham Young University. The group came up with a gadget called the Poket Doktor, a prototype of a microchip-embedded smart card that uses Bluetooth wireless technology to relay medical information at the scene of an accident even if the patient is unable to communicate.
Healthcare providers would issue encrypted cards to patients on which up to 32 KB of vital health information - allergies, surgical history, blood type, current medications - is electronically stored. Emergency medical personnel would then be outfitted with handheld Poket Doktor devices capable of automatically detecting medical cards in a victim's wallet or purse and accessing that information at accident scenes or in the emergency department.
The device even addresses security concerns. The encrypted medical data stored on Poket Doktor could be unscrambled only by a physician or paramedic with laptop, cell phone, or handheld computer programmed with reciprocal software.
Bluetooth, a wireless communications protocol named after the Danish Viking chieftain who united Norway and Denmark in the tenth century, is expected eventually to unite the telecommunications industry under one wireless networking standard. The revolutionary technology uses an inexpensive radio transmitter the size of a dime, employing short-range radio waves to transfer information wirelessly between digital appliances within 60 feet of each other.
With Bluetooth, computer peripherals like printers and scanners - and perhaps one day imaging modalities - can be liberated from the usual kludge of connecting cables. While Bluetooth devices are still rare, estimates suggest that by 2005 more than 700 million will ship annually.
The Institute of Electrical and Electronics Engineers (IEEE) thought enough of the Poket Doktor idea to award it third place in the June world finals of the IEEE Computer Society International Design Competition.
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.
