C.8.5.5.1.3 Region Flags​

Region Flags (0018,6016) specify characteristics of US Regions.​

Bit 0 of the Region Flags specifies the relative priority of the pixel component calibration specified by an US Region in the case where​ the US Region intersects with other US Regions. The calibration supplied by one or more of the regions may not be valid in the area​ that they intersect.​

Enumerated Values for Bit 0 (lsb):​

0​Region pixels are high priority​ 1​Region pixels are low priority​

A high priority region overwrites data of a low priority region when they overlap, thus invalidating any pixel component calibration​ specified for a low priority region. pixel component calibration of overlapping regions of the same priority is indeterminate where they​ overlap. Figure C.8-6 shows an example of intersecting regions.​

Region A

Region B

Point X +

Point Y +

Point Z +

Region C

Figure C.8-6. Intersecting Spatial Format Regions and Overlapping Measurement​

In this example, Region B is Color Flow while Region A is Tissue Echo. If Region B Color Flow values share the same bit planes as​ Region A Tissue Echo values, then it is indeterminate whether a pixel in this region is a Color Flow pixel or a Tissue Echo pixel. Since​ the pixels of the Color Flow region overwrite those of the Tissue Echo region, the Region Flag of the Tissue Echo region is assigned​ low priority and the Region Flag of the color region is assigned high priority. This means that if both the Tissue Echo and Color Flow​ regions define pixel component calibration that only the calibration specified by the Color Flow region can be applied to the pixel data​ value at Point X.​

The measurement in Figure C.8-6 is a line between Point Y and Point Z. Both points are in Region A so the distance between them​ can be calculated using the Region A scaling (assuming that Region A defines both the Physical Units X Direction and Y Direction​ as being cm). If the points are in Region B, and hence also in Region A, it is still possible to calculate the distance because the region​ scalingisidenticalinbothregions.ThelowerpriorityofRegionBonlyappliestoitspixelcomponentcalibration,notitsXandYdirection​ scaling.​

Enumerated Values for Bit 1 Scaling Protection:​

0​Not Protected​ 1​Protected​

Ultrasound systems should set this to 1 if the image is scaled automatically by the ultrasound system. If the image is frame-grabbed​ and scaling is not available then it should be set to 0. If the region is protected, the region can not be manually rescaled. That is the​ data defined by the region calibration Module can not be overridden by a reader of that image.​

Enumerated Values for Bit 2 Doppler Scale Type:​

0​Velocity​ 1​Frequency​

Valid for PW and CW regions only. Indicates which type of Doppler scale is used.​
