Abstract
A CT apparatus comprises; a sensor section outputting distance data for determining a distance between the sensor section and at least part of a subject to be examined laid on a cradle; contour-data generating means for generating contour data representing a contour of the at least part of the subject based on the distance data obtained from the sensor section; and deciding means for deciding whether or not there is a risk for said subject to come into contact with said gantry while said gantry or said table is moving based on data representing a limit of a range up to which said subject can come close to the gantry and on said contour data.
Claims9
A contact avoidance apparatus for avoiding contact of a subject to be examined laid on a cradle of a table with a gantry, said apparatus comprising:
- a sensor section for acquiring distance data for determining a distance between said sensor section and at least part of said subject laid on said cradle;
- contour-data generating means for generating contour data representing a contour of said at least part of said subject, wherein the contour-data generating means determines information on positions of points on a body surface of said at least part of said subject with respect to said cradle based on said distance data, and generates said contour data based on said information on positions;
- and
- deciding means for deciding whether or not there is a risk for said subject to come into contact with said gantry while said gantry or said table is moving based on data representing a limit of a range up to which said subject can come close to said gantry and on said contour data.
A medical apparatus comprising:
- a gantry;
- a cradle on which a subject to be examined is laid;
- a sensor section for acquiring distance data for determining a distance between said sensor section and at least part of said subject laid on said cradle;
- contour-data generating means for generating contour data representing a contour of said at least part of said subject, wherein the contour-data generating means determines information on positions of points on a body surface of said at least part of said subject with respect to said cradle based on said distance data, and generates said contour data based on said information on positions;
- and
- deciding means for deciding whether or not there is a risk for said subject to come into contact with said gantry while said gantry or said table is moving based on data representing a limit of a range up to which said subject can come close to said gantry and on said contour data.
A computer readable storage medium storing a program applied to a contact avoidance apparatus for avoiding contact of a subject to be examined laid on a cradle with a gantry using distance data for determining a distance between a sensor section and at least part of said subject laid on said cradle, said program being for causing a computer to execute:
- contour-data generating processing of generating contour data representing a contour of said at least part of said subject, wherein the contour-data generating processing determines information on positions of points on a body surface of said at least part of said subject with respect to said cradle based on said distance data, and generates said contour data based on said information on positions;
- and
- deciding processing of deciding whether or not there is a risk for said subject to come into contact with said gantry while said gantry or said table is moving based on data representing a limit of a range up to which said subject can come close to said gantry and on said contour data.
