Searching and Sorting

09:54 pm

Got my hands on Yadnesh Sanzgiri's Paper. Went through. Pretty cool. After spending at least a week since the beginning of my project, on trying to search for any information regarding any ultrasound doppler signal database, or their classification, I have realised that they do not exist on the net. Not even on physionet. A first concern!! Because a lot  depends on it. Got to think of alternatives.

Have to meet the ultrasound specialist who Rohan Naik from micro was talking about! It seems he's free most of the times. We'll see if he's got anything of my concern. Either information about how diagnosis of Placental Insufficiency is done based on the audio doppler, or the database.Can I do without it? I guess NOT.

Coming to the review Presentation, guess the sequence to progress would be this:

• What is Placenta? It's function and importance. What is Placenta Insufficiency? Its ffects. Diagnosis workflow in short, emphasis on Umbilical Artery Doppler and middle cerebral artery doppler (Image).
• Discussion of audio doppler. Comparison of information content in Audio and Image. Thus importance of Audio diagnosis. But not much research, very less papers available.Thus the aim of the paper.
• Summary of 2 papers that I've found on the subject.
• What is doppler effect? Application in our case of  Biomedical Diagnosis(UAD and MCA). Explanation in short how Image and audio sounds are produced (have a paper + textbook xerox for explanation).
• Planned signal Processing using MATLAB and Neural Network: Looking through Principal Component Analysis, Independent Component Analysis, Wavelet and variations available with combinations of these. Their comparison to find out which would be the appropriate one.
• Basic study of neural network.

Preparation for all this will take at least 7 days + 2days apprx 10 days. Assuming week after Ganesh Chaturthi are the reviews, I have just about 14 days in hand. Gotta make each day count.

1. Gotta catch hold of that Ponda Ultrasound Specialist and find information about audio indications of Placental Insufficiency, and see if he can give me some database.

2. Gotta start getting the presentation ready, because then I can just take excerpts from this and make the report for submission at the time of the review. Considering the number of days at hand and bullets as mentioned, each bullet can afford around 2 to 3 days. Starting from the day after tomorrow because tomorrow is my father's 66th birthday, gotta kinda celebrate type of a thing.

Nothing else on my mind right now. The way our external guide told us to go ahead with the project makes no sense considering the direction of the project, and doing it just for the sake of it is not the luxury I can afford to take considering the time and effort required to do it first according to him, and then redo it according to me. Have to put my foot down! Here we go! Sorted!
