Quantitative Doppler imaging in both velocity norm and direction, as well as amplitude contrast of either zebrafish Background Managing indeterminate-depth burn wounds remains challenging. Laser Doppler Imaging (LDI) has been validated for burn wound depth and can influence the clinical assessment. Our study investigated the value of LDI as an adjunct in determining the need for excision. Methods Seventy American Burn Association (ABA)-verified burn centers were surveyed. Background: Despite various exisiting monitoring methods, there is still a need for new technologies to improve the quality of post-operative evaluation of digital replantation.
Employs a 2mW near infra red laser scanning beam In fast scan mode the time for 256 x 256 scan measurements is about 5 minutes. Default upper bandwidth of the signal (Doppler frequency shift) processor is 15kHz, so that in fast scan mode the range of red blood cell speeds that contribute to the recorded image is about 0.075mm/s to 6mm/s. The purpose of the study is using a laser Doppler imaging device (Easy-LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue. The method most used to determine burn depth is clinical assessment, which is the least expensive, but not the most accurate.Laser Doppler imaging (LDI) is a technique with which a more accurate (>95%) estimate of burn depth can be made by measuring the dermal perfusion. PURPOSE OF PRESENTATION/STUDY: To compare the accuracy of Laser Doppler Imaging (LDI) and clinical assessment in differentiating between superficial and deep partial thickness burns to decide whether early tangential excision and grafting or conservative management should be employed to optimize burn and patient management. INTRODUCTION: Laser Doppler imaging (LDI) is a relatively new method for assessing the functional aspect of superficial skin blood flow in systemic sclerosis (SSc) and Raynaud's phenomenon.

The purpose of the study is using a laser Doppler imaging device (Easy-LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue. Laser Doppler imaging ( LDI) can be used to measure superficial blood flow in the skin and other vascularized tissues.
Using Laser Doppler Imaging and Monitoring to Analyze
Laser Doppler imaging ( LDI) can be used to measure superficial blood flow in the skin and other vascularized tissues. A laser Doppler perfusion imager functions by projecting a visible-to- infrared laser beam onto the surface of a tissue.
