AN OVERVIEW OF MEDICAL IMAGING TECHNIQUES USED IN BREAST CANCER

  1. 1. S.A.P.D.J PATHSHALA’S WALCHAND INSTITUTE OF TECHNOLOGY, SOLAPUR AN OVERVIEW OF MEDICAL IMAGING TECHNIQUES USED IN BREAST CANCER Presented by: Guided by:Inamdar Farhan (TE ENTC) Prof. V.H.Kondekar (ME Computer Networks)Gudur Venkateshwarlu(TE ENTC) Prof.A.V.Thalange (ME VLSI & Embedded systems)
  2. 2. Introduction to cancer What is cancer? Disordered growth of cells in the human body is termed as cancer. How cancer arise? Cells become cancer cells because of damage to DNA
  3. 3. The normal breastBreast cancer:Breast Cancer is a form of cancer that occursin the breast tissue.Symptoms:Swelling of all or part of a breast Skin irritationBreast or nipple painNipple retraction (turning inward)Redness, scaliness, or thickening of the nipple or breast skinNipple discharge (other than breast milk)
  4. 4. Types of breast cancers  Ductal carcinoma in situ  Lobular carcinoma in situ  Invasive (or infiltrating) ductal carcinoma  Invasive (or infiltrating) lobular carcinoma
  5. 5. Detection of Breast Cancer and tumors Importance Importance of screening Screening refers to tests and exams used to find a disease, like cancer, in people who do not have any symptoms.
  6. 6. Different types of imaging techniques Imaging refers to obtaining an image. Following are the various methods used for breast imaging:1. Mammogram2. Magnetic Resonance Imaging3. Digital mammogram4. Breast Ultrasound - Imaging5. Digital Infrared Thermal Imaging6. Breast Optical Imaging
  7. 7. Mammogram A mammogram is an x-ray of the breast. Brief Introduction. Advantages.
  8. 8. Magnetic Resonance Imaging MRI scans use radio waves and strong magnets. Principle. Applications.
  9. 9. Digital mammogram Digital mammograms are recorded and stored on a computer, similar to a digital data. Advantages: Data flexibility
  10. 10. Breast Ultrasound – Imaging High-frequency sound waves are used. How it is done? Advantages: Ultrasound imaging is a noninvasive medical test Used in real time observation
  11. 11. Digital Infrared ThermalImaging It uses the electromagnetic waves characteristics of the body. It mainly uses metabolic activities of tissues How it is done?
  12. 12. Breast Optical Imaging It employs diffuse light that propagates through tissue. It uses optical characteristics of tissues.
  13. 13. Breast cancer in men Many people today think only women can develop breast cancer but little do they know that men can, too. Seriousness of breast cancer in men. How to overcome or prevent?
  14. 14.  Computer-Aided Detection ofBreast Cancer CAD systems have been developed for analyzing digitized film/screen images. Importance of CAD. Advantages over manual detection.

  17. 17. Future scope  In India, which is a developing country and where breast cancer treatment is not much developed, early detection of breast cancer using the different imaging techniques is very important.  There is an increase in the Indian breast cancer patients in future. In those situations early detection techniques are must. CAD tool proves very useful and increases the overall efficiency of breast cancer detection and they should be researched well.
  18. 18. Conclusion Due to genetic and life style number of breast cancer is increasing in women. Imaging techniques are helpful for early detection of cancer. Digital Mammography is the important of all and has a very wide scope and importance in the future. It flexes data handling. Breast cancer is possible in men also. It is very critical in men and should be detected and treated as early as possible. CAD tools improve the accuracy of detection. In India where there is a high chance in increase in number of breast cancer patients, breast cancer is a serious problem. Imaging techniques are the need of the day.
