A Modified and Improved Method for Detection of Tumor in Brain Cancer

Abstract

precise information of a tumor plays an important role in the treatment of malignant tumors. The manual segmentation of brain tumors from Magnetic Resonance images (MRI) is time consuming task. Processing of MRI images is one of the parts of this field. The detection and extraction of tumor is done from patient's MRI scan images of the brain. The basic concepts of the image processing are some noise removal functions, segmentation and morphological operations. The modified image segmentation and histogram thresh holding techniques were applied on MRI scan images in order to detect brain tumors. In addition, a region prop and skull is used to detect the tumor in the brain. The proposed method can be successfully applied to detect the contour of the tumor and its geometrical dimension. The result of present paper has been very promising. The anatomy of brain states that the patients with the single brain metastasis may benefit from cytoreductive surgery in the combination with whole brain radiotherapy in terms of prolonged functionally independent survival though overall survival has not been shown to improve. Meningioma's represent the other end of the scale as these tumors may undergo gross total resection with high rates of the long term survival. It is used in order to obtain the relevant tissue for histological investigations remain the primary diagnostic modality. In case of brain abscesses, puncture and culturing of sampled material provides a microbiological diagnosis. Stereotactic biopsies used the frame based systems. These systems are well documented in terms of precision, high diagnostic yield and low rate of complications. The stereotactic computers are applied in neurosurgery. These systems are helpful tool in pre operative planning. A stereotactic computer has been used instead of a frame for various intracranial procedures. For the better detection off the brain tumor a skull mounted guide system was developed. This system is coupled with a stereotactic computer and it permits the puncture of intracranial mass lesions. The morphologic investigations of tumor tissue remain a gold standard for diagnosing brain tumors. A final diagnosis is commonly based upon post operative histology evaluation of the paraffin embedded material.
