As represented by conventional radiograph, radiological images provide only black and white figures in 2D space. The situation is basically the same for Single photon emission tomography (SPECT) and positron emission tomography (PET), which are the two most common molecular imaging techniques used in nuclear medicine. PET is used especially for early cancer and Alzheimer’s…

Waseda University researchers have developed a process to dramatically improve the quality of 3D printed resin products. The process combines greatly improved surface texture and higher structural rigidity with lower cost, less complexity, safer use of solvent chemicals and elimination of troublesome waste dust. Kensuke Takagishi and Professor Shinjiro Umezu, both of the Waseda University…
