plane

 [plān]
1. a flat surface determined by the position of three points in space.
2. an imaginary flat surface that divides the body into sections (see accompanying figure). adj., adj pla´nar.
3. a specified level, as the plane of anesthesia.
4. to rub away or abrade; see also planing and plastic surgery.
5. a superficial incision in the wall of a cavity or between tissue layers, especially in plastic surgery, made so that the precise point of entry into the cavity or between the layers can be determined.
Planes of section. Transverse, sagittal, and frontal planes of the body. From Applegate, 2000.
coronal p's frontal p's.
datum plane a given horizontal plane from which craniometric measurements are made.
frontal p's those planes passing longitudinally through the body, an organ, or a part, at right angles to the median plane and dividing into front and back portions. Called also coronal planes.
horizontal plane transverse plane.
median plane one passing longitudinally through the body, an organ, or a part from front to back, dividing it into right and left halves.
sagittal p's vertical planes through the body parallel to the median plane or the sagittal suture, dividing the body into unequal left and right portions.
transverse plane one passing horizontally through the body, an organ, or a part at right angles to the median and frontal planes, dividing it into upper and lower portions. Called also horizontal plane.
vertical plane one perpendicular to a horizontal plane, such as a sagittal plane, median plane, or frontal plane.

trans·verse plane

[TA]
a plane across the body at right angles to the coronal and sagittal planes; transverse planes are perpendicular to the long axis of the body or limbs, regardless of the position of the body or limb; in the anatomic position, transverse planes are horizontal planes; otherwise the two terms are not synonymous.
Synonym(s): plana transversalia [TA]

trans·verse plane

(trans-vĕrs' plān) [TA]
A plane across the body at right angles to the coronal and sagittal planes.

trans·verse plane

(trans-vĕrs' plān) [TA]
Plane across body at right angles to coronal and sagittal planes; perpendicular to long axis of body or limbs, regardless of position of body or limb; in the anatomic position, they are horizontal; otherwise two terms not synonymous.

The purpose of this study was to develop a scoliosis model by modulating spinal growth in the coronal, sagittal, and transverse planes using NT coil springs.
The ratio between the distance from the IOF to the infraorbital margin and the distance to the transverse plane crossing the lower margin of the piriform aperture (D/E) was calculated as 0.47 [+ or -] 0.75 mm and 0.51 [+ or -] 0.75 mm for the Byzantine period skulls and 0.39 [+ or -] 0.13 mm and 0.43 [+ or -] 0.13 mm for the modern skulls, for the right and left sides respectively.
The transverse plane moments during the WA and MS were small when compared with the sagittal and frontal plane moments and never became greater than 0.12 Nm/kg.
In the transverse plane, in Figure 7(b), the difference was higher and was approximately 11.5 mm.
Hence if [H.sub.z]([rho], [phi], z) distribution is known at an arbitrary transverse plane, e.g., z = [z.sub.0], the TE mode coefficients, [[sigma].sup.TE.sub.mn], can be obtained from
[u.sub.N], yielding the result in (2), where [g.sub.ki] are dimensionless real coefficients that only depend on the geometry of the MTL, and where each magnetic voltage [14,19] is defined in (3), the open integration path [??] belonging to the transverse plane. Note that in a transverse plane, where H is a gradient field, the concept of magnetic voltage is equivalent to magnetic scalar potential difference.

When many electrodes are placed along a transverse plane, the pattern of regional impedance to an injected electrical current can image the lung according to those properties, producing a cross sectional "tomographic" image that complements the more detailed anatomic image obtained from CT slices of the region.
