Visible light is a treatment option for Segmental Vitiligo (SV), and visible light-induced repigmentation is associated normalization of sympathetic. Currently it is difficult to predict individual patient's response to visible light therapy. Therefore, the present invention uses the Laser Doppler Flowmeter to serve as a response predictor for visible light on treating SV. The present invention recruited 14 Segmental Vitiligo patients for evaluating clinical information. FirstLaser Doppler Flowmeter was used to evaluate the cutaneous blood flow of SV lesion and contralateral normal skin, and then treated them with visible light irradiate, cold-stress, rewarmed, and recorded the change of skin blood flow, finally the patients received regular visible light treatment for 3 months, and patients have a sign of repigmentation after the treatment.

Motility contrast imaging (MCI) is a depth-resolved holographic technique to extract cellular and subcellular motion inside tissue. The holographic basis of the measurement technique makes it highly susceptible to mechanical motion. The motility contrast application, in particular, preferably includes increased mechanical stability because the signal is based on time-varying changes caused by cellular motion, which should not be confused with mechanical motion of the system. Apparatus for motility contrast imaging that provides increased mechanical stability is disclosed. It is based on common-path configurations, in which the signal and reference beams share optical elements in their paths to the detector. The two beams share mechanical motions in common, and hence these motions do not contribute to the signal.

Using both quantitative MRI and quantitative MRS, the inventor demonstrates herein that as age and dementia progress, hippocampal volume (HV), amygdala volume (AV), and NAA/mI ratio all decrease compared to normal controls. The inventor's data also demonstrate herein that NAA/mI vs. total amygdala volume showed a very strong linear correlation, while NAA/mI vs. mean total hippocampal volume had a lesser but still significant correlation. Further, after analyzing the data derived from both quantitative MRI and quantitative MRS methods, the inventor made the surprising discovery that the two tests, when combined, provide significantly improved biomarkers over either alone, and are more effective at early MCI and/or AD diagnosis, as well as HS diagnosis.

Method and Apparatus to Detect the Fragmentation of Kidney Stones by Measuring Acoustic Scatter

Номер: US20140081174A1

During shock wave therapy, a determination is made that a kidney stone has begun to fracture, and then a progress of its fragmentation is assessed. This determination can reduce the number of shock waves used to disintegrate kidney stones, and thereby reduce dose-dependent tissue damage. The identification of fracture is possible through the detection and analysis of resonant acoustic scattering, which is the radiation caused by reverberations within a stone particle that is struck by a shock wave. The scattering frequency can provide both an indication that the kidney stone has fragmented, and an indication of the relative sizes of the fragments. Related concepts employ displacement measurements of kidney stones/fragments to provide both an indication that the kidney stone has fragmented, and an indication of the relative sizes of the fragments. Such techniques can be combined with vibro-acoustography based gating that better targets the stone. 1(a) detecting a resonant acoustic scattering wave to generate a resonant acoustic scattering signal during therapy, the resonant acoustic scattering signal being indicative of internal stress vibrations in the kidney stone, where the internal stress vibrations are in response to shock waves impacting the kidney stone;(b) processing the resonant acoustic scattering signal to determine a frequency spectrum of the stress vibrations; and(c) monitoring the frequency spectrum of the stress vibrations during therapy in order to determine if the kidney stone is fragmented, by detecting a change in the frequency spectrum, the change in the frequency spectrum being indicative of fragmentation..
