Final answer:
The false statement regarding CT systems is that 2) they cannot generate a straight coronal or sagittal image. Modern CT scanners can reconstruct images in various planes and have moving parts, contrary to the claims that they have no moving parts and cannot be fixed.
Step-by-step explanation:
Computed Tomography (CT), also known as Computed Axial Tomography (CAT), is a medical imaging technique used extensively since its development in the 1970s. It operates on the principle of obtaining multiple cross-sectional X-rays around the body part being scanned. By analyzing the varying degrees of X-ray absorption or reflection, CT systems are able to provide high-resolution two-dimensional images, which can be further processed to form detailed three-dimensional visualizations.
The statement that CT systems cannot generate a straight coronal or sagittal image is false. Modern CT scanners are quite capable of reconstructing images in the coronal, sagittal, or even oblique planes after the initial scanning in the axial plane. These reconstructions are made possible by powerful computer algorithms that process the acquired slice data. Additionally, CT scanners indeed have moving parts—the X-ray tube and detector array rotate around the patient to acquire images from multiple angles. Regarding repair and maintenance, CT systems can certainly be fixed as needed. The answer is option 2.
