Introduction Most colonoscopies are completed in the left lateral (LL) position but in cases of suboptimal caecal preparation, changing the patient's position to supine (S) and, if needed, to right lateral (RL) improves caecal intubation rate, mucosal visibility, and adenoma detection. Aim To determine if position change during colonoscopy facilitates optimal visualisation of the caecum. Ma...

A new approach to the detection of the position and the orientation of planar motion objects based on onesided Radon transform is presented. Detection of position and orientation of planar motion objects is a key to advanced object handling. First, one-sided Radon transform is introduced and its properties are investigated. Second, algorithms to detect planar motion of objects are constructed b...
