The temperature of the gradient coils is an important issue in the development of MRI scanners.
Furthermore, the development of reliable scanners, based on moving optics for guiding high power lasers at extremely fast speeds allows the rapid motion of laser spots, resulting on tailored shapes of swept areas by the laser.
Meaning that if you see any politician (or pundit or whomever) trying to say, "We need these new scanners ASAP; we may not be so lucky next time," well, kindly point them in the direction of Ben Wallace, who was involved in the development of said scanners before he became an MP in the UK.
The projects included the development of fingerprint scanners, migrant-detecting drones and vehicles, satellite surveillance, and overground and underwater border patrol robots.
More recently, advances in imaging hardware technology have led to the development of hybrid scanners capable of performing anatomical and functional imaging sequentially in the same session.
The development of hybrid scanners with CT-based AC combined with new iterative reconstruction methods incorporating SC should facilitate QSPECT reconstruction.
Of note, the development of μMRI scanners at 9.4 T allows for a detailed assessment of experimental cartilage repair, especially when dedicated transmit/receive coils for small samples are employed [ 18- 21].
Future development of CT scanners will further reduce the amount of radiation and thus increase the possibility to improve the accuracy of this method by allowing higher resolution with the same radiation exposure.
It is also worth noticing that most interest, from the technology advance point of view, has been put on the development of portable 3D scanners: first, 3D scanners are still more expensive than traditional camera-based systems; second, they are hardly applicable if objects are moving.
