Abstract
A method includes receiving a multi-phase axial cardiac dataset, receiving a selection of a phase from a user, when the received selection is systole, generating an endocardial volume of a left ventricle at an end systole phase without further user intervention, and when the received selection is diastole, generating an endocardial volume of the left ventricle at an end diastole phase without further user intervention.
Claims18
A method for generating views of a heart, said method comprising:
- scanning a patient's heart using an imaging scanner to generate a multi-phase axial cardiac dataset;
- transferring the multi-phase axial cardiac dataset to a computer;
- receiving a selection of a heart phase from a user at the computer, said selection comprising at least one of a systole phase and a diastole phase;
- segmenting a left cavity volume image of the heart from the multi-phase axial cardiac dataset;
- calculating an axis of inertia of the segmented left cavity volume image;
- automatically generating, based on the calculated axis of inertia, at least one of a long axis orientation image and a short axis orientation image of the heart;
- and
- generating an endocardial volume of a left ventricle at an end of the selected phase without further user intervention, wherein the generated volume excludes a plurality of papillary muscles.
A medical imaging apparatus for generating views of a heart along anatomically useful planes, said medical imaging apparatus comprising:
- an imaging system comprising:
- a detector array;
- at least one radiation source;
- a computer coupled to said detector array;
- and
- a workstation coupled to said computer, said workstation configured to:
- receive a multi-phase axial cardiac dataset from said computer;
- receive a selection of a heart phase from a user;
- segment a left cavity volume image of the heart from said multi-phase axial cardiac dataset;
- calculate an axis of inertia of said segmented left cavity volume image;
- and
- automatically generate, based on said calculated axis of inertia, at least one of a long axis orientation image and a short axis orientation image of the heart;
- and
- generate an endocardial volume of a left ventricle at an end of the selected phase without further user intervention, wherein the generated volume excludes a plurality of papillary muscles.
A combination comprising:
- a computer;
- and
- a computer readable medium encoded with a program executable by the computer for generating views of a heart along anatomically useful planes, said program configured to instruct the computer to:
- receive a multi-phase axial cardiac dataset of the heart;
- receive a selection of a phase;
- segment a left cavity volume image of the heart from said multi-phase axial cardiac dataset;
- calculate an axis of inertia of said segmented left cavity volume image;
- automatically generate, based on said calculated axis of inertia, at least one of a long axis orientation and a short axis orientation image of the heart;
- generate an endocardial volume of a left ventricle at an end systole phase without further input;
- generate an endocardial volume of the left ventricle at an end diastole phase without further input;
- provide the generated volumes to a user for at least one of a verification and an edition of a myocardial contour for the volumes, wherein the generated volumes exclude a plurality of papillary muscles;
- and
- receive at least one of an indication of verification by the user and an edit from the user.
