A new administration dose index for optimization of acquisition time at PET imaging using count data using an ionization type survey meter. (snmmi.org)
Also, since MR involves no radiation and the scan allows a longer PET acquisition time, the patient's exposure is lower than with CT.. (sciencedaily.com)
Unfortunately, detecting traditional luciferases» dim light emissions requires long acquisition times that may be impractical or infeasible for certain experimental setups. (blog.addgene.org)
