Organ motion has been previously described using a probability distribution function that depends solely upon the amplitude of motion and the degree of asymmetry in the breathing cycle, and that function has been used with patient specific parameters to correct static dose distributions for patient breathing using a dose convolution method. In this study, the consequences of errors in the selec...

Aim: A case report of 17 year male patient with osteochondroma humerus bone.Method: presented swelling left arm since 16 months. On X-ray there was bony stalk present no neurovascular involvement in same limb. Patient planned for removal tumor lesion fibula cortical graft fixed screw.Result: had full range motion at shoulder and elbow joint incorporated 6

according to abū al-barakāt baghdādī, time and place are a priori conditions of motion; moreover, against the peripatetic philosophers, for whom time is the measure of motion, he holds that time is the measure of existence. nevertheless, he believes that we can define motion on the basis of our intuitive non-scientific concept of time and, by so doing, we can resolve the apparent circularity of...

Introduction Patient motion in high resolution in time-of-flight (ToF) MR angiography (MRA) results in blurring and signal loss. Autocorrection is an iterative, retrospective algorithm that has been shown to be useful in correcting motion artifacts induced by translational motion in high-resolution shoulder MR images [1]. The purpose of this paper is to report on the application of autocorrecti...

PURPOSE This project proposes using a real tissue phantom for 4D tissue deformation reconstruction (4DTDR) and 4D deformable image registration (DIR) validation, which allows for the complete verification of the motion path rather than limited end-point to end-point of motion. METHODS Three electro-magnetic-tracking (EMT) fiducials were implanted into fresh porcine liver that was subsequently...

Cardiac Motion artifacts in PET are a well known problem. The heart undergoes two types of motion, the motion due to respiratory displacement and the motion due to cardiac contraction. These movements lead to blurring of data and to inaccuracies in the quantification. In this study a continuity equation based optical flow method is presented and results on 3D PET patient datasets for cardiac mo...
