Anode heat capacity is a critical aspect of computed tomography (CT) technology, as the anode can generate significant heat during the imaging process. It is essential to measure the heat generated and absorbed by the anode in standardized units that reflect the amount of energy involved.

While joules (J) is a well-established unit of energy in the International System of Units (SI), measuring heat capacity in million heat units (MHU) provides a more practical framework when dealing with the large amounts of heat generated in imaging systems. This unit captures the cumulative heat energy, allowing for easier handling and understanding of heat transfer and dissipation in CT scanners.

Using heat units in thousands or millions simplifies communication about heat capacities among professionals in the field, especially given the significant thermal loads experienced by the anode during operation. Hence, million heat units serve as a suitable and commonly accepted metric in the context of anode heat capacity.
