A table-mounted stereotactic system for digital angiography: a means of standardizing arteriovenous malformation measurement.
A detachable noninvasive table-mounted stereotactic device is described for use with digital radiography. The device is designed for standard two-view orthogonal projections but may be adjusted to allow for projections angled from the axial plane. When applied to the imaging of arteriovenous malformations (AVMs), it negates the influence of a variety of geometric and mechanical factors which would otherwise interfere with the determination of size. An accurate appreciation of AVM size, in turn, would allow a more reliable means of categorization of AVMs into distinctive groups for classification purposes and prognostication.
