Computed tomography (CT) productivity is not solely determined by the number of slices. Entry-level CT models, often with fewer slices, are widely available globally, suggesting cost-effective platforms could enhance CT accessibility.
Area of Science:
- Medical Imaging Technology
- Health Systems Research
Background:
- Computed tomography (CT) is a vital diagnostic tool.
- Understanding the productivity and market supply of CT models is crucial for healthcare access.
Purpose of the Study:
- To evaluate the productivity of computed tomography (CT) models.
- To characterize the global market supply of entry-level CT scanners.
Main Methods:
- CT exam times were measured across six stages in Brazilian health facilities.
- Productivity was calculated by comparing weekly working time to total exam time.
- An internet search identified global manufacturers and their entry-level CT models.
Main Results:
- Exam time variations were minimal and primarily due to non-acquisition stages.
- Entry-level CT models offered globally include 2- to 4-slice (Asia, South America, Africa) and single-slice options.
- US market shows models below 16-slice.
Conclusions:
- CT scanner productivity does not scale linearly with the number of slices.
- Shareable platforms could reduce CT costs and improve availability.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
