With lessening of the vasospasm, a 2 mm AcomA aneurysm was subsequently identified (figure 1).
(A) Still image during coil embolization with use of microangiographic fluoroscope detailing coil, the microcatheter and its distal marker, and the interface between the microcatheter and the coil. (B) Working anteroposterior view during coil embolization with standard fluoroscopy. Compared with (A), the resolution of the microcatheter and the coil is much lower.

The MAF was instrumental in evaluating the relationship of the microcatheter and extruding coil to provide superior control and details of intra-aneurysmal microcatheter and coil behavior (figure 2).

The MAF detector has four major components arranged as shown in figure 3: a 300 mm cesium iodide input phosphor, a dual-stage second-generation microchannel plate light image intensifier (LII) attached to a minifying fiberoptic taper coupled to a charged-coupled device chip (CCD).
