The use of Matlab 6 1 software on the original speckle image processing for speckle contrast pseudo-color map and at each time point blood flow diagram, the more red color represents the corresponding flow faster. The picture shows the baseline at 0 min pseudo-color flow, at each time point on the pseudo-color flow image and compared, 6 of Matlab. 1 software, obtained 10 min after 10 min under normal conditions and oppression to stimulate hemodynamics change the percentage of the spinal cord. Studies have shown that laser speckle imaging technique can be accurate, dynamic, living, non-contact monitoring of spinal cord hemodynamic changes, visual observation of the vascular morphology and blood flow velocity changes in the solid spinal cord compression, irritation or injury before and after as well as drug hemodynamic changes in the intervention conditions to provide a really reliable monitoring. It is the related log of  400mw green laser pointer.
In rat cerebral blood flow in ultra-deep hypothermia under laser speckle imaging monitoring. This is the Ministry of Education Key Laboratory of Biomedical Photonics, Huazhong University of Science and Technology - Wuhan National Laboratory for Optoelectronics (chips), Zhang Li, Peng-Cheng Li, Ni Songlin had Shaoqun, Luo Qingming, such as a few people together to complete. Acute onset of severe acute cerebral ischemic diseases, severe illness, a serious threat to human health, the treatment of severe acute cerebral ischemic disease at home and abroad is still less developed. Hypothermic brain protection to a significant protective effect on cerebral ischemic injury has been a lot of experimental research and clinical applications proved [1,2]. (9) low-temperature treatment to improve cerebral blood circulation, stabilize vascular function, reducing the energy metabolism of brain cells. The document can be the reference of 300mw red laser .
The study found that brain temperature decreased more low, the less nerve cell energy metabolism and oxygen consumption, the better the brain cells, the protective effect can be effectively blocked serious cerebral ischemic diseases the pathological damage of brain cells process [3]. Brain tissue temperature quickly dropped to the ultra-deep hypothermia (≤ 16 ° C) level, while body temperature remained at normal body temperature, not only to achieve good brain protective effect and to avoid systemic deep hypothermia treatment in the complex heart and lung damage caused by temperature process [3]. But the ultra-deep hypothermic brain protection mechanism is unclear, and need to clear deep hypothermia cerebral protection time window. The clinic is necessary to ensure the normal biological tissues from the damage of ultra-deep hypothermia. The log of 300mw red laser gathers much information. cheap Laser Pointers
They need to maximize the ultra-deep hypothermia treatment effect, and thus ultra-deep hypothermia to time selection is particularly important. Blood flow to supply oxygen and nutrients for biological tissue, its dynamics reflect the state of biological tissue metabolism and physiological functions. Hemodynamic monitoring in the diagnosis and treatment of clinical disease provides important information, has become the essential means of monitoring in the clinic. Blood flow in vivo detection of the laser Doppler technique [4] has been widely used, but this technique is only suitable for monitoring the flow rate of a single vascular monitoring is required, such as vascular flow rate of the large area the scanning device, thus limiting the time or spatial resolution of imaging. The document of reference concerning 300mw red laser is very important.
And this method of transmission way to measure the vascular flow rate, and to treat the measured level of transparency of the organization's higher. In recent years, Briers et al [5] proposed a laser speckle imaging techniques, also known as laser speckle contrast ratio analysis techniques, there is no need to scan to get the regional distribution of blood flow, and the method using reflection imaging modalities to measure blood flow, vascular level of transparency does not require more extensive use than existing methods. This technique has been used to monitor the skin [6], retinal fundus changes in blood flow [7] and drug effects on rat mesenteric blood flow dynamic changes [8] and stimulation of the sciatic nerve of rat cortical blood flow dynamics change [9]. When necessary, the document of 300mw red laser can be referred.
