Abstract The 123I-labeled meta-iodobenzylguanidine (MIBG) is an analogue of noradrenaline that can evaluate cardiac sympathetic activity in scintigraphy. Quantitative analysis of 123I-MIBG images has been verified in patients with heart failure and n

In case that a lot of products were cut out from a wide base sheet by laser cutting, the sheet had been much deformed so that the error occurred in a height regulator. This paper deals with thermal deformation of a base sheet caused by laser cutting.
