Abstract: This study tries to reach an approach for hemorrhage control process based on using Nd:YAG laser, in order to reduce the time needed for coagulation. The Nd:YAG laser with its different powers and modes is one of the most widely used lasers in medical applications . The research shows that this laser type is a powerful and useful method for haemostaisis, one of the most important medical applications of laser with no mentioned side effects. The work in this study describes the improvement of haemostaisis time by using Nd:YAG laser.

Several types of laser are used in laser angioplasty and in experimental works to study the effects of laser on blood vessel and blood clot. They differ from each other by a lot of properties mainly in wavelength, energy of the laser and pulse duration. Argon laser, CO2 laser and Nd: YAG laser are used widely in the ablation of atheroma and in the recanalization of occluded vessels. In this study Argon laser (488 nm- 514 nm), Co2 laser (10.

During the last few decades, the field of medical image processing has been closely related to neural network methodologies and their applications, especially after the vast successful researches in this field and the advanced newly formulated algorithms as well as the need for accuracy and intelligence in assessing of the medical images in critical diagnosis and oncology care cases.
