A Conjunct Analysis for Breast Cancer Detection by Volume Rendering of Low Dosage Three Dimensional Mammogram
Breast cancer is the fifth most common cause of cancer death after lung cancer,stomach cancer,liver cancer,and colon cancer.Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women.The earlier the breast cancer is detected the more the chances of treatment and even cure.If detected early,the five-year survival rate exceeds 95%.A majority of breast cancers are diagnosed as a result of an abnormality seen on a mammogram.A mammogram is actually a 2-D x-ray image of the breast.The radiologist,who specializes in reading x-ray images,can identify differences between a normal breast and one that may show signs of cancer.Mammography is a test that allows the doctor to look at images of the inside of the breasts.However,it is possible for a 2D mammogram to look normal even though a breast cancer is actually present.This is more common in patients of younger age where the breast tissues are denser and thus spotting an abnormality becomes difficult.Also,it is possible for a 2D mammogram to look abnormal when there is actually no cancer and in this case additional testing is required.To overcome limitations of these kinds in breast cancer detection,the patient had to undergo additional testing procedures.One such additional procedure is the recently developed 3-D(Tomosynthesis)technology which allows us to see cancers that might be hidden and using a three-dimensional image along with a 2-D mammogram provided a clearer picture.Despite the fact that 3D mammography eliminates overlapping of tissue that is seen in conventional 2-D mammograms,it was noted that using 3-D mammography technique as an adjunct with 2-D mammograms doubled the radiation dose the patient received,increasing cancer risk.This paper gives an idea of how 2D image can be obtained from the 3D mammogram data without the need to take 2-D slices additionally and hence avoiding issues related to over dose of radiation.Volume rendering technique is proposed which displays a 2D projection of a 3D discretely sampled data set.
