Hi Luis,
Well i could perform 3d Registration after tunning the input =
parameters...My actual data sets are 512x512x205 and 128x128x205. Since =
this is a huge data set i started with one slice of each, =
2d-Registration, then with 35 slices, then 100 slices, then 150 slices, =
then 175 slices and now 205 slices. The problem is for the original data =
sets ie. 512x512x205 and 128x128x205 it is taking nearly 1300Mb of =
systems memory. Why it is so...The total size of two data sets are =
109Mb.. Even it is not performing one iteration but the size of the =
memory is going on increasing....At last it is giving "Abnormal Program =
Termination" error message. What could be the problem? Is it because of =
unsufficient memory or its ITK related error. My system has 512Mb RAM =
and nearly 1000Mb virual memory...Mine is P3 processor....Even my =
application is not getting control of the CPU...System Idle Process is =
getting focus most of the times....What could be the reason....=20
I could get the Registered output for 175 slices each....But for =
205....it gives error....Even for 175 slices it takes more memory.....
My parameters to the Registration are:-
No. of Iterations :- 150.
Translation Scale :- 100000.
No. Of Bins :- 50
Spatial Samples:- 1000
Max Step length:- 2.0
Min Step Length:- 0.01
No. of Levels:- 3
=20
Shrinking factors
CT images :- 16 16 8
PET Images:- 4 4 8
What could be the problem??? Is it with the ITK or with system =
memory??? Any estimate of system memory for these data sets???
Please help in this regard.
=20
Thanks in advance.
-Regard,
Sateesh.
