Correcting Respiratory Motion Blur in PET Images Based on Phantom and Deconvolution Algorithm
MENG Xiang-HCHEN Yang-CZHENG Dong-QDepartment of Physics,Jinan UPET-CT Center of the First Affiliated Hospital of Guangzhou Medical U
Motion blur in PET images induced by respiratory motion may influence the accuracy of tumor diagnosis and treatment. In this paper,a method of correcting the motion blur,which combined high-frequency sinusoidal vibration model and deconvolution technology,was proposed. The high-frequency sinusoidal vibration model is used to simulate the tumor motion due to respiration. The blur direction was identified by performing Radon transform on the quasi-cepstrum of motion blurred image. The blur extent was identified from bispectrum of motion blurred image rotated to make the motion direction vertical. Based on this,Richardson-Lucy iterative algorithm is used to correct respiratory motion blurs. Experiments on phantom images show that both the tumor volume and mean standard uptake value( SUV) derived from restored images are closer to the pared to un-correction motion blur images,the error of tumor volume estimation was decreased from 40% to10%,and the error of SUV is decreased from 28% to 4%. The results demonstrate that the proposed correction approach can improve the accuracy of PET quantification by correcting the respiratory motion blurs.

The potential of transdermal drug delivery systems has been demonstrated in recent years with the approval of several medicines for use by patients who are unable to use conventional dosage routes, like oral administration or injection. To enhance the TDDS (Transdermal Drug Delivery System) potential to include other drug candidates, many researchers have been exploring enhancement approaches to increase the permeability of various drugs through the skin. Recently, physical enhancement systems are being reported as having big potential by many researchers. In particular, iontophoresis is a very attractive way of delivering ionized drugs by the application of an electric field to the skin. This has been marketed with some topical and systemic drugs (lidocaine and fentanyl). Sonophoresis is also an attractive method to deliver a drug through the skin using ultrasound. Besides these technologies, various physical approaches are under study. Such technologies can be expected to deliver not only small MW compounds but also macromolecules like peptides. In this article, after looking back through the history of TDDS development, I would like to summarize with new physical and chemical approaches and outline of the new trend of TDDS development with those enhancement system.
