Table 1.
Characteristics of the normal patients.
Fig 1.
Determined planes (red lines) to extract torso region.
(a) Neck-Shoulder (NS) plane. (b) Arms-Chest (AC) planes (left/right). (c) Thigh-Hips (TH) plane. (d) Anterior and Posterior (A, P) planes.
Fig 2.
Area distributions in sagittal and axial directions to determine NS and AC planes.
Fig 3.
An example of labeled images in waist (a) and thigh (b) regions to be used for determining the TH plane.
Fig 4.
Area distributions in coronal direction to determine Anterior (A) and posterior (P) planes.
Head region was excluded to count.
Fig 5.
Automated configured points to represent NS, TH, A, P, BL and LV planes.
Fig 6.
Given control points to register body surface.
Fig 7.
Calculated distributions of mean and SD in SUV for male and female in a coronal plane.
Actual distributions are in 3D. (a) Mean distribution for male. (b) SD distribution for male. (c) Mean distribution for female. (d) SD distribution for female.
Fig 8.
Distribution of SUVmax vs Z-score.
It is apparent that the Z-scores of the most abnormal cases are greater than 2.0.
Fig 9.
Example of abnormal accumulation (colon cancer).
The SUV of 2.1 was converted into Z-score of 5.73, because the mean and SD at the location (an arrow) were 0.61 and 0.26, respectively.
Fig 10.
Example of normal accumulation (bladder).
The SUV of 65.4 was converted into Z-score of 1.84, because the mean and SD at the location (an arrow) were 19.6 and 24.9, respectively.

Standard body and registration example in a coronal plane.
(a) A male standard body selected from normal database. (b) An another normal body to be deformed to the standard body shown in (a). (c) A result of physique registration. (d) A result of physique and bladder registration. (e) A result of physique, bladder, and liver registration. (f) A result of physique, organ, and surface registration.
