conclusion the study data highlighted good value of iodine-based material decomposition images of spectral ct in assessment of both lipiodol deposition and residual cancer for follow-up of hcc patients previously treated with tace. background it is critical to follow up hepatocellular carcinoma (hcc) after transcatheter arterial chemoembolization (tace) in clinical practice. computed tomography...
Spectral decomposition is a powerful analysis tool used to identify the frequency content of seismic data. Many spectral decomposition techniques have been developed, each with their own advantages and disadvantages. The basis pursuit technique produces a high time frequency resolution map through formulating the problem as an inversion scheme. This techniques differs from conventional spectral...
This paper presents a review of spectral decomposition of seismic data, since it's inception nearly in 1997. It discusses various techniques and applications of spectral decomposition in seismic data processing and interpretation. It is also known as timefrequency analysis consists of transforming non stationary signal in time/space from time/space domain to time/space vs frequency domain. The ...
spectral decomposition of time series has a significant role in seismic data processing and interpretation. since the earth acts as a low-pass filter, it changes frequency content of passing seismic waves. conventional representing methods of signals in time domain and frequency domain cannot show time and frequency information simultaneously. time-frequency transforms upgraded spectral decompo...
