IMAGING APPARATUS FOR DIAGNOSIS AND PROBE

摘要

An imaging apparatus for diagnosis is provided in which a simpler configuration enables an anatomical technique and a physiological technique to be used in combination. The imaging apparatus for diagnosis disclosed herein includes a first calculator for calculating a parameter indicating each deformation degree of measurement slit portions, by using a tomographic image including the measurement slit portions which are disposed at different positions in an axial direction of a probe unit and whose cross-sectional shape is deformed in response to a pressure applied to the probe unit, and a second calculator for calculating a value corresponding to a myocardial fractional flow reserve, based on the calculated parameter.

主权项

1. An imaging apparatus for diagnosis comprising:
a probe unit that includes a sheath and a transmitting and receiving unit located in the sheath, the transmitting and receiving unit transmitting and receiving a signal, the transmitting and receiving unit being controlled so as to transmit and receive the signal while rotating inside the sheath in a circumferential direction or while rotating in the circumferential direction and moving in an axial direction, the probe unit including deformation portions whose cross-sectional shape is deformable in response to an external pressure, the deformation portions being disposed at different positions of the sheath in the axial direction; first calculation means for calculating multiple parameters which indicate a deformation degree of the respective deformation portions disposed at the different positions in the axial direction, by using a tomographic image including the deformation portions; and second calculation means for calculating a value corresponding to a myocardial fractional flow reserve, based on the multiple parameters.
