The detection efficiency of the Compton camera reaches about 15% and 3% for 100 keV and 511 keV gamma rays, respectively.
Luminescence intensity values were converted into photons/min based on the rated quantum efficiency and gain of the camera.
For a typical brain tumor treatment, the overall detection efficiency of the optimized Compton camera was approximately 0.1425% using the Snyder's head phantom with a sphere tumor (4 cm diameter and ~1 cm depth).
The team made use of Havok's Behavior toolset for character animation, which allows for a greater fluidity between the character's movements of walking, running and sprinting, and also increases the efficiency of the third-person camera option which had been criticized in Oblivion.
Experimental results show the efficiency of our camera motion-based summary.
The high EMCCD gain and the quantum efficiency of nearly 60% of the camera allows to observe single atoms in the MOT as well as in the optical lattice (see Figure 6).
This is due mainly to the low efficiency of the classic Anger gamma camera and its parallel-hole collimation, and additionally to the limited spatial resolution (SR) and energy resolution (ER) of the sodium iodide crystal and the process of light scintillation.
However, photographic film is unsuitable for high-throughput methods because it has to be handled manually, while the efficiency of CCD cameras is limited because the electrons have to be converted into visible light to be detected.
In the case of Renilla, new red-shifted and more stable mutants with an emission peak at 535 or 547 nm have been produced by site directed mutagenesis [7], but dual color imaging still remains difficult to perform in part due to the relative low quantum efficiency of CCD cameras below 500 nm (30%), where the native enzyme shows the peak of emission.
We tested the efficiency of the multicamera tracking system over a four camera system.
However, few of these studies address numerical physical simulation of the camera, and it is difficult to track lighting technology for forward simulations because of its low efficiency.
