Image Quality Assessment of Non-contrast Brain Computed Tomography Using High-pitch Double Spiral Scan: A Basic Evaluation Using Phantom
In the phantom experiment, the 10% TTF values of the FS images were comparable to those of the reference images, indicating similar resolution in the high spatial frequency domain. FS is expected to expand the applicability for detecting cerebral hemorrhage in patients with significant body movement, where detection is challenging under standard conditions.
