Abstract
An apparatus for detecting and measuring changes in the shape of a wall of a body includes a detector capsule adapted for attachment to the wall and pneumatically connected to a volume transducer responsive to changes in the internal volume of the apparatus produced by changes in the shape of the wall. The internal volume of the capsule is partially defined by a flexible diaphragm for engagement and complementary movement with the wall. The capsule contains a resiliently deformable material which presses the diaphragm into contact with the wall regardless of the convex or concave shape of the wall.
