Final answer:
CT image data can be stored on an internal hard disk, CD, or re-writable optical disk. These storage media vary in capacity and accessibility with CDs and similar optical media using laser technology for precise data recording and storage.
Step-by-step explanation:
CT image data which is large in size due to the high resolution and detailed information it contains can be stored on various types of storage media. The three common storage media types that may hold CT image data are:
- Internal hard disks, which provide fast access and large storage capacity,
- CDs (Compact Discs), where data is stored digitally on the surface in the form of pits read by a laser, and
- Re-writable optical disks, such as CD-RWs or DVD-RWs, which allow data to be written, erased, and re-written.
The content loaded onto these storage media varies in terms of accessibility, portability and capacity. For example, when compared to audio and video cassette tapes CDs can store significantly more data including large sets like encyclopedias. The laser technology employed in CDs and similar optical media allows for precise recording of data leading to the high storage capacities required for comprehensive data like CT images.
