A medical image has dominated the compression techniques since it requires to have a smaller size of the image and should maintain the relevant diagnostic information.Reducing the size of the image, directly give impact to the transmission speed.This paper presents an approach towards compression algorithm development using discrete curvelet transform.Curvelet functions signify functions which have discontinuities along straight lines where wavelet functions are not properly worked.The curvelet transform algorithm were synthesized using MATLAB and various medical modalities such as computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound are used as a sample's medical images.The results obtained clearly identify that discrete curvelet transform algorithm gives a good quality for the reconstructed images.
