Automatic Fast Detection of Tumor Suspect Areas on CT Scan
Our research deals with a fully automatic and fast visualization of possible tumoral areas on CT Scan images. To achieve this task, we use the bilateral symmetry of the human body and the asymmetry introduced by the presence of tumors. Our work was initially dedicated to the head and neck area but it should work well for any other body part and even better for more symmetric areas like the brain. Image 1 Figure 1 After observing the specialists modus operandi for tumor detection on CT Scan images, we realized that any lack of bilateral symmetry was for them a serious alert. Than they look more carefully to the gray levels and to the structure regularity of the image to precisely locate the tumor. So we make our computations on the image reduced to only 12 gray levels: a few gray levels means that we have a global view of the image and we do not care about details and this is what specialists do first. A very important parameter is the Mid Sagittal Plane (MSP in Image 1): this is the s...
