All spectra ultimately saved and analyzed consisted of the even nanometer data from the down-scan interleaved with the odd nanometer data from the return scan. A Labview (National Instruments, Austin, TX) program was developed to handle all scanning, baseline correction, data acquisition, and file...
Microspectrophotometry (MSP) was conducted using a computer-controlled, single-beam instrument, previously described57, that classifies visual pigments based on their distinct spectral absorbance characteristics and measures spectral sensitivities, and hence determines the performance and spectral limits of visi...
which is visible when the CT scan comprises only the angled needle. It has been reported that the “low density” artifact visible immediately adjacent to the distal part of the tip of the needle may create a false positive impression; therefore, the correct position of the needle must be de...
