ABSTRACT
Objective To introduce the clinical application of BHP9504 fluorescent analytic instrument.Methods The chemical immunofluorescent test was used in high-precision,high-stability photo-signal test by photon counting technology.Results Photo-signal test could examine strong photo-signals in dark background so that it was able to improve sensitivity of experiments.Conclusion This technique widens the range of application and reduces specimen amount.
ABSTRACT
Objective To design a new type of RF endorectal coil so as to increase signal to noise ratio(SNR) and improve the efficiency of MRI diagnosis.Methods Through circuit and construction optimization,a MRI model of coil in vivo was designed.Results The images and spectroscopy of a special phantom were acquired and the results were compared to those of the commercial TORSO coil.Conclusion This coil gives a significantly higher SNR at the region of interest(ROI).The achieved high local SNR and resulting high spatial resolution can add more anatomic and biochemical information to the diagnosis of prostate diseases.
