Imaging condition determining method and an X-ray CT apparatus
First Claim
1. An imaging condition determining method for an x-ray CT apparatus for performing imaging by a helical scan, comprising the steps of:
- making a table of various imaging conditions in advance;
extracting a first candidate imaging condition from said table in accordance with an age, imaging region, imaging length of a patient, and the highest-priority objective specified by a user, and displaying an exposure dose of the patient under the first candidate of imaging condition;
enabling the user to adjust said exposure dose; and
determining a second candidate imaging condition adjusted in response to the adjustment of said exposure dose.

Abstract
An imaging condition determining method for an x-ray CT apparatus for performing imaging by a helical scan. The method includes making a table of various imaging conditions in advance, extracting at least one imaging condition from the table in accordance with age, imaging region, imaging length of the patient as well as the highest-priority objective specified by a user, and displaying the exposure dose of the patient under the at least one imaging condition, enabling the user to adjust the exposure dose, and determining the imaging condition adjusted in response to the adjustment of the exposure dose to the at least one imaging condition.
