Brain perfusion SPECT is a non-invasive nuclear medicine imaging technique that allows regional CBF evaluation. The technique includes four main components: the CBF radiotracers (radiopharmaceuticals)‚ instrumentation‚ image reconstruction‚ and CBF quantification. 1.1.1 CBF radiotracers The inert gas xenon 133 is one of the most important and classical radiotracers for CBF measurement in absolute units using SPECT []. Nevertheless‚ the poor spatial resolution and the requirement for dedicated instrumentation

Abstract In this project our main objective is to detect the tumor and calculate its area based on classifying the images. Death rate among people has been increased due to diseases like brain tumor. The brain tumor that can be identified by using image processing. The proposed system enables automatic detection of brain tumor through MRI. So our main objective is to study‚ analyze and enhance MRI Image from the existing algothrim. Certain traditional approach requires manually extracting the location

Measuring Brain Activity Most of the noninvasive imaging methods estimate brain activity by changes in blood flow‚ oxygen consumption‚ glucose utilization‚ etc. Discuss the potential problems with using this type of indirect measure. The brain is the control center of the human body. It sends and receives millions of signals every second‚ day and night‚ in the form of hormones‚ nerve impulses‚ and chemical messengers. This exchange of information makes us move‚ eat‚ sleep‚ and think.

the years scientists have discovered that there is more to the brain than previously thought. They have learned that inside the brain there is a synapse or an area that is open between the axon of a nerve and the dendrite of another nerve. The synapse entails the neurotransmitters‚ mitochondria‚ postsynaptic ending that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors
