2. · Information gathering · Data analysis · Decision making · “ Human life is too important to be left to a computer “ Patients receive the best treatment on the best evidence available

3. · We must accept our limitations · Computers allow us to access up to date research worldwide · research is there to assist us not undermine our ability Shared information advances our knowledge. Encourages us to expand our practices. Scrutiny of all research to validate validity. No one person can have all expert knowledge it is important to collaborate with all professional colleagues · Use good karma always

4. ·  is a soft ware · is an increasingly role as decision making tool’s · are being applied in several health care areas e.g digital mammography and AAP

5. · Cancer Breast ♂ : ♀ 1-15 · 40% of CA Breast Benign · In Norway 2100 new cases,800 deaths/year · Early detection ↓ mortality · Screening program based on mammography ↓ mortality · ↑ no of countries started mass screening programs →increased no mammography interpretation.

6. · Abnormalities embedded, camouflaged by varying densities of breast tissue · 10 – 30 % of ca breast missed by radiologist · CAD design to detect, classification clustered micro calcification nodules

7. · Image segmentation : detection, extraction of clustered micro calcified nodules from back ground breast tissue · Extracted micro calcification nodules categorized as benign or malignant ( image classification )

8. · Clustered micro calcification early signs ( potential cancerous changes) · Micro calcification small ca ++ deposit accumulate is breast tissue as a bright spot · Cluster defined to be at least 3 micro calcifications with in 1-2 cm region of mammogram · Individual micro calcifications range 0.1 – 1.0 mm ( in mammogram)

9. · Main goal of ACD system provide a second opinion · 2nd opinion radiologist use result of pc analysis of mammogram in making a diagnosis · Digital mammogram → feature extraction → classification → analysis → detected tumor.

10. · To generate segment the mammogram into 2 classes clusters of micro calcification normal tissues · To generate features used to discrimination benign and malignant clusters of micro calcifications

11. Over last 20 Years studies in U.K, Europe in AAP shows : · 2-3.000.000 / year with AAP · Cost Euro 1.5 million/ year  · AAP not a diagnosis in the strict sense but rather a symptom

12. · The most common frequent decision which surgeon called upon is not merely related to precise diagnosis but rather to operate or observe? · General rules of investigation : Know what you are doing? don’t waste time?, know what you want ?

13. · Main goal early diagnosis and correct management · Initial diagnosis accuracy 45 % · Perforated app rate 30% (delayed diagnosis ), -ve app rate 30% · In Europe last year 200.000 app removed too late, 200.000 normal app removed

14. . Patient centric data ( direct related to patient ). Aggregates data based on performance and utilization ( resources management data). Transforming – based data for planning, clinical and management decision support. Comparative data for health services researches.

15. Computer aided decision support system “ CADSS “ is AAP began in 1970 by professor Tim de-Dambal Decision making improved by fall in –ve laprotomy and rate of perforated appendicectomies

16. Initial diagnostic accuracy rate rose from 45.6% - 63.5 % -ve laprotomy rate fall by almost half perforation rate amongst patient with appendicitis fall 23.7 % - 11.5 % Mortality rate fall by 22.0% Direct cost saving of over 5 m Euro

17. CAD useful system for improving diagnosis and better clinical practice 450 physician is 64 hospitals is 19 countries ↓ residual diagnosis error rate by 40% ↓ unnecessary operation by 25% ↓ in perforation rate of appendicitis case by half

18. Changes is like dragon fight it you will loose.,ignore it., it will eat you., success only favors those who challenge it. Patients needs change constantly so therefore we must respond accordingly to new advancement in technology
