Algorithm Calculating the Ratio of Cerebrospinal Fluid to the Skull

The results presented in this article introduce the possibility of software processing by image data from CT and MRI in clinical practice. It is important to work with the most accurate data in the diagnosis and further monitoring of the patient. Especially in the case of birth defects or post-traumatic conditions of head called Hydrocephalus, it is necessary to work with this data. A production increase of the cerebrospinal fluid, called cerebrospinal fluid (CSF), causes bring intracranial pressure up. The oppression of the brain tissue has resulted of this. The determination of CSF ratio to the skull in medical practice is used to improve diagnosis and monitoring before and after surgery in patients with Hydrocephalus diagnosed. The evaluation is done by individual doctor experience. The proposed method brings a new opportunity to more accurate evaluation of medical data in this area. Software was implemented in Matlab2006b using Image processing Toolbox. Input data format is JPEG images.
