Abstract:
1. An image diagnostic system comprising: a radial scanner; a probe positionable in a body cavity and configured to repeatedly transmit signals and acquire line units of signals reflected from biotissue surrounding the body cavity with the radial scanner; an encoder configured to generate output signals corresponding to rotational angles of the probe upon performing the radial scanning; a control system connected to the probe to receive the acquired reflected line units of signals and produce digital data based on the acquired reflected line units of signals and to construct a tomographic image of the body cavity and the biotissue surrounding the body cavity on the basis of the digital data; and a display unit configured to display the tomographic image; the control system comprising: a conversion unit configured to convert the acquired reflected line units of signals into digital line data and output the digital line data responsive to successive inputs of the synchronization signals selected by the selection unit for use in constructing the tomographic image.
