Star Trek at 50 - Focused Ultrasound Surgery

In the late 1980s holograms seemed like the next big thing in imaging, after computerized tomography (CT) and magnetic resonance imaging (MRI), because they added depth. Imaging systems were becoming increasingly important as minimally invasive surgical procedures – such as endoscopy (surgery using a tube camera) and laparoscopy (belly surgery, usually through the navel) – took off. By taking the data from the MRI and CT to create a hologram of a tumor and then projecting that into the body during surgery, a surgeon could cut out a tumor while avoiding healthy tissue. Lasers might be able to accomplish this, but so would high-frequency waves of sound. And why not use the ultrasound for the surgery itself?

This week, a look at the greatest leap in medicine since the scalpel, focused ultrasound surgery,

Star Trek at 50: Biometrics

Biometrics refers to metrics related to human characteristics. Biometrics authentication (or realistic authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance.

It has been suggested that biometrics originated in the identificatory systems of criminal activity developed by Alphonse Bertillon and developed by Francis Galton's theory of fingerprints and physiognomy.


Regardless of where it started, it is around us every day. iPhones use fingerprint identification. Walt Disney World takes an image of your finger, converts the image into a unique numerical; the numerical value/ticket combination facilitates ease of re-entry into the park and helps prevent fraud. Washington State has an option for an Enhanced Driver's License that utilizes facial recognition to allow for border crossings into Canada without a passport, a necessity if you're after some Timbits®.
 
This week, a look at Biometrics.
