Mind Tumor Detection Paper

The human mind is the center of a person’s reasoning and thoughts and today it has gone from a mystery to a unique feature in the human anatomy. The mind is home to one's consciousness, perception, thinking, judgement, and memory. The brain also controls a person's muscle movement, breathing, and even their body temperature. Its anatomy is so complex that many doctors and scientists are continually learning and understanding how the different features of the brain work together to function as one of the body’s most interesting organs. Those who do study the way the brain and the nervous system function together are quite brilliant and are one of the most dedicated group of doctors. There are many fields

Brain cancer develops from cells within the brain. The brain controls the vital functions of the body, including, speech, movement, thoughts, feelings, memory, sight, hearing, and more. Brain cancer affects people in many different ways. Brain cancer is diagnosed at the local stage in 76.6% of people. The 5-year survival for localized brain and other nervous system cancer is 36.3%. Brain cancer will cause anything from headaches to balance and walking problems, changes in your vision, muscle twitches, memory problems, and nausea and vomiting.

MRP can provide a valuable tool in initial diagnosis as well as staging of different brain diseases and pathologies. Following that, MRP can also aid in differentiate between the true and pseudo progression, differentiate between high and low grade Glioma, differentiate between infectious and neoplastic focal brain lesion, and detect the efficacy of anti-angiogenic cancer therapy, identifying the real tumor margin as well as guiding stereotactic

The brain tissue of a Neonatal is different from the adult brain because the adult brain is a well-developed one but the brain tissue of a neonatal brain is in developing stage, also it is very small in dimension, and fluid movement inside the brain during the scan make it difficult to differentiation various tissues. Hence a refined Neonatal Brain image processing technique is

Neuroimagery is a clinical speciality that produces images of the brain by using non-invasive techniques, i.e.: without requiring surgery, incision of the skin, or any direct contact with the inside of the body. This type of imagery falls into two categories: Structural; this deals with the structure of the brain and aids the diagnosis of diseases (e.g. brain tumours) and Functional; this is used for neurological and cognitive research purposes, along with the diagnosis of metabolic diseases (e.g. Alzheimer’s and Parkinson’s). Neuroimagery enables us to directly visualize the processing of information by the centres of the brain. This processing causes the involved area of the brain to increase metabolism and as a result highlight itself

This article specifically explores what type of slicing would be necessary to asses different sized tumors, and the relation between the information revealed based on thickness of the scans.

A brain tumor is a collection (or mass) of abnormal cells in the brain. The skull is very rigid and the brain is enclosed, so any growth inside such a restricted space can cause problems. Brain tumors can be cancerous or non-cancerous. When benign (non-cancerous) or malignant (cancerous) tumors grow, they can increase the pressure inside the skull. This can cause brain damage and even death. Radiologists examine the patient physically by using Computed Tomography (CT scan) and Magnetic Resonance Imaging (MRI). These medical are used in surgery, irradiation planning and tumor treatment. Figure 1 shows MRI image. It shows that tumor tissues are brighter than normal tissues. To segment the tumor is challenging

Primary intra-axial brain tumors represent the two-thirds of all brain neoplasms whereas the metastases represent the remaining one-third [1]. As a group, gliomas are the most common brain tumors including Astrocytoma and like many tumor types, the exact cause of Astrocytoma is not known [2].

Brain tumors have been taking over the bodies of individuals for years, and many of them go without a defined cause. Many doctors and medical professionals believe brain tumors are caused by exposure to carcinogens, whether it be environmental or synthetic. Before one can understand the risk factors, they must first understand what exactly a brain tumor is, the risk factors for brain tumors, and the different forms of terminology. There are a few key locations in the brain that are important to know when talking about brain tumors. Those include: the cerebellum, cerebrum, spinal cord, and brainstem. The cerebellum is the lower, back part of the brain, which controls one’s balance,

Brain Cancer is a big disease that affects the nervous system. Brain cancer is a tumor in the brain. Not all tumors are cancerous, but most are. If a cancerous tumor in the brain is discovered early enough, it can be treated, without taking desperate measures. Depending on where the tumor/cancer is, it can affect how the body functions. Some signs of brain tumors/cancer are:

Magnetic resonance imaging is one of the common clinical method for the diagnosis of brain disorders, evaluation of desease progression and follow-up treatment. In other hand, any neurological disorder frequently has specific effects on brain tissues structure so, segmentation of brain tissues gives information of its current severity. Although, manual segmentation of brain MRI is still a highly used method, it is a time consuming task and subject to high intra_ and inter_ observer variability so, automated brain tissue segmentation method is required. In this study, we proposed a dictionary learning and sparse presentation based method for automated segmentation of healthy brain tissue including white matter, gray matter and cerebrospinal

Besides the tumour heterogeneity, the boundaries of the tumour may be composite and visually unclear to detect at the earlier stages. Some tumour may collapse the adjacent structures in the brain. Furthermore, artefacts and noise in the brain tumour images complicates the obscurity in tumour detection. Hence developing an efficient and automatic image segmentation approach is necessary to provide a better tumour detection performance especially in MRI brain

With the aim of rising a number of existing strategies and developing new techniques to facilitate correct, quick and reliable computer-based diagnosing of malignant melanoma, this thesis makes contributions in numerous stages of development of a computer-aided diagnostic system of melanoma; particularly, image acquisition ,image segmentation and border detection, feature extraction, feature selection, and

Brain Imaging techniques allow doctors and researchers to view activity and detect problems without having to have invasive surgery.They are immensely popular in the field of psychology , they provide the opportunity to study the active brain and allows researchers to see where brain processes take place. Brain imaging techniques are also helpful when studying localisation of function in a living human brain. Brain scans only provide correlation between behaviour and brain activity not causation. MRI ( Magnetic Resonance Imaging ) uses magnetic fields and radio waves to produce 3D computer-generated images. It distinguishes between different types of soft tissue and allows researchers to see different structures within the brain. Some strengths

There are several approaches for extracting ROI in natural images like that are stated in [5] [6], but these techniques are not suitable for medical images. In [7], there are two methods of extracting ROI from medical images which are based on Mean square error and thresholding. But these methods do contains limitation like, the MSE approach require a reference image which is practically not
