Three-dimensional imaging of a subject on a subject support

A medical system comprising,

• a subject support wherein the subject support comprises a support surface for receiving a subject,
• a first camera configured for imaging a first portion of the support surface;
• a second camera configured for imaging a second portion of the support surface, wherein the first portion and the second portion comprise an overlapping region, wherein the subject support is movable relative to the first camera and the second camera along a predetermined path between a first position at least one intermediate position, and a second position, wherein each of the one or more intermediate positions is located between the first position and the second position;
• a memory containing machine executable instructions and
• a computational system configured for controlling the medical system, wherein execution of the machine executable instructions causes the computational system to:
• control the first camera to acquire initial first camera image data descriptive of a subject on the subject support when the subject support is in the first position;
• control the second camera to acquire initial second camera image data descriptive of the subject on the subject support when the subject support is in the first position;
• construct an initial three-dimensional image of the subject using at least a portion of the overlapping region of the initial first camera image data and the initial second camera image data;
• identify as a first obstructed region a region of the subject imaged by the initial first camera image data but obstructed in the initial second camera image data;
• and
• identify as a second obstructed region a region of the subject imaged by the initial second camera image data but obstructed in the initial first camera image data;
• control the subject support to move to one of the one or more intermediate positions;
• control the first camera to acquire additional first camera image data descriptive of the subject on the subject support when the subject support is in the one of the one or more intermediate positions;
• control the second camera to acquire additional second camera image data descriptive of the subject on the subject support when the subject support is in the one of the one or more intermediate positions;
• construct a first camera three-dimensional image of the subject using the initial first camera image data and the additional first camera image data;
• construct a second camera three-dimensional image of the subject using the initial second camera image data and the additional second camera image data;
• construct a composite three-dimensional image of the subject using the initial three-dimensional image, the first camera three-dimensional image, and the second camera three-dimensional image, wherein the first obstructed region is at least partially replaced by the first camera three-dimensional image, and wherein the second obstructed region is at least partially replaced by the second camera three-dimensional image.
