Tumor segmentation from magnetic resonance imaging (MRI) is important for volume estimation and visualization of nasopharyngeal carcinoma (NPC). In some cases, segmentation using the general multispectral (GM) method often obtained poor results due t

Passive Q-switching of a diode-pumped Nd : YVO 4 laser was demonstrated using GaAs as an output coupler and as a saturable absorber. When pumped with a 3-W diode laser at 809 nm, the highly compact laser produced 12-μJ pulses of 2.2 ns in duration a

Tumor volume is an import diagnostic and prognostic factor for tongue carcinoma (TC). Currently, tumor volume of TC is estimated by measuring the maximal diameter or depth of tumor, or by summing the areas which are manually traced by a radiologist,
