What is the effect of doubling the beam width while maintaining the same pitch?

Doubling the beam width while keeping the same pitch has a direct impact on the volume of tissue irradiated during the scan. When the beam width is increased, more tissue is covered with each rotation of the CT scanner. As a result, the amount of radiation that is delivered to the patient also increases. This means that the radiation dose received by the patient rises, which is why this answer is considered correct.

In CT imaging, the beam width is crucial as it determines the amount of data collected for each slice. Maintaining the same pitch means that the relationship between the movement of the table and the beam width stays constant, but increasing the beam width allows for more data acquisition per rotation. This increase in beam width necessitates a higher radiation dose to maintain image quality, thereby leading to an increased overall radiation exposure to the patient.

Other options may seem appealing but do not accurately describe the consequences of doubling the beam width. When beam width is increased, scan time does not necessarily decrease; in fact, more data can mean longer processing overall. Similarly, while one might assume that spatial resolution could improve due to more coverage, it is impacted by factors like voxel size and the capabilities of the scanning system rather than simply beam width alone. Thus, increased radiation
