i need matlab code for finding the lung tumor intensity using ct scan image

am doing project in medical image segmentation. now i need to find the intensity of the lung tumor cell. so pls anyone help me. am new to matlab

[Nitin]

What are you trying to achieve exactly? It would be helpful if you could upload an image and explain your problem.

thanks for ur responce.i post wat i need to achieve exactly,i have uploaded the image.interms of pixels i want to find the intensity of tumor.based on the intensity value radiotherapy treatment is done.this wat i need to achieve.help to do

Dear sir, iam doing a project in img segmentation can you suggest a new algorithm to find lung tumor, please give me responce

Answer 1

[sri nandhana]

i need to find the lung tumor density by using ct scan. interms of maximum pixels i want to do. i have attached the image file. initially i did edge detection ie)canny edge detection and found the edges of the tumor cell. then i want to find the intensity of the tumor cell based on the intensity value radiotherapy treatment will be done.can u pls suggest me algorithm for this.

I agree with Nitin, please expand what you mean by intensity of the tumor? Do you need to find and extract tumor into a smaller image? find the max pixel value? average pixel value of the tumor? if anything http://www.mathworks.com/programs/ip_cd/ is a webinar on using matlab for image processing. It should be enough of an introductory on ways for you to find the tumor and get certain properties of it. If you are just looking to get some pixel value just use the data cursor after you load in the CT scan and either do a imagesc() or image().
