EXPLORER PET scanner – fast!
Human PET (Positron Emission Tomography) scanning is used frequently to determine the metabolism of glucose in the body which help find cancer and also for finding specific molecules using specific PET probes. However, PET scanners are expensive to operate, expose the body to radiation and also require long amounts of time for the patient in…

Imaging: Precise real time Three dimensional Hand Mapping.
It is typically difficult to map in three dimensions (3D) at a very close distance in high precision very quickly. There are different ways to accurately represent three dimensions but that requires a 3D scanner that will take a number of “images” with light or infrared or sonar and then map it correctly. However, if…

Photoacoustic imaging
It is difficult to image at high resolution using conventional optics to any reasonable depth below the skin. There are many ways to counteract this and one unique method is called photoacoustic imaging. This method was invented by Lihong Wang at Washington University in St Louis. The phenomenon of acoustic imaging is fascinating use of…

Spider robot molded cheaply
Cheap robots by the millions Typically it costs many hundreds of dollars to make a robot that can do something substantial. However, researchers at the Fraunhofer institute have created molded or stamped robots that can be created very cheaply – they imagine them to be like disposable gloves. Make them, use them and then throw…

Nanotube label free imaging
A researcher, Ji-Xin Cheng, at Purdue university has figured out a label free method to label carbon nanotubes. Nanotubes are typically hard to see and with Cheng’s technique not only can you see the nanotubes but you can also visualize them within cells. The method is known as transient absorbtion and uses a pulsed near…
