In an embodiment, a flexible multi-arm catheter is provided, having up to thirty-two sensing electrodes 24 (e.g., sixteen opposing pairs) patterned on each flexible spine 27.
导管40由八个脊制成，使得设置在导管40处的感测电极的总数多达256个电极。
Cather 40 is made of eight spines, making the total number of sensing-electrodes disposed at catheter 40 up to 256 electrodes.

步骤340包括至少部分地基于所测得的电子发射物中的入射能级来确定被吸收的能量(即，被吸收到构建层192内的总能量或电子的数量)。
Step 340 includes determining the absorbed energy (i.e., the total energy or number of electrons absorbed within build layer 192) based at least in part on the incident energy level in the measured electron emissions.
在这方面，例如，电子发射物(包括二次电子、反向散射电子和透射电子)中的被吸收的电子之和应等于入射能级。
In this regard, for example, the sum of the absorbed electrons in the electron emissions (including secondary, backscattered, and transmitted electrons) should be equal to the incident energy level.
由于改性表面层的厚度小，因此认为表面化学主要影响二次电子发射物。
The surface chemistry is believed to mostly affect the secondary electron emission because of the small thickness of the modified surface layer.
因此，通常可以通过从入射能级减去所测得的电子发射物来确定被吸收的能量。
Thus, the absorbed energy may generally be determined by subtracting the measured electron emissions from the incident energy level.
步骤350包括至少部分地基于所测得的电子发射物来调整电子束的入射能级。
Step 350 includes adjusting the incident energy level of the electron beam based at least in part on the measured electron emissions.
在这方面，控制器220可以响应于所测得的电子发射物来调整电子束122(例如，包括总射束能量和能量密度两者)的入射能级，使得被吸收的能量追踪目标能级。
In this regard, the incident energy level of electron beam 122 (e.g., including both total beam energy and energy density) may be adjusted by controller 220 in response to measured electron emissions such that the absorbed energy tracks a target energy level.
以这种方式，方法300有助于调整电子束122的入射能级以补偿电子发射物的波动，从而导致对构建过程的更多控制以及更高质量的零件或部件190。
For example, the target energy level may vary depending on the position of the focal point 180, on the type of additive powder used, the thickness of build layer 192, etc. In this manner, method 300 facilitates the adjustment of the incident energy level of electron beam 122 to compensate for fluctuations in electron emissions, resulting in more control over the build process and higher quality parts or components 190.
