Question

The property that determines the number of characters of field can hold is represented by it.
a) field length
b) format
c) field size​

Answer 1

Answer:

The Field Size property determines the number of characters of field can hold is represented by it.

Explanation:

Field size means the dimensions along the major axes of an area in a plane perpendicular to the central axis of the useful beam of incident radiation at a normal treatment distance and defined by the intersection of the major axes and the 50 percent isodose line.

Material shall be placed in the beam such that dose maximum is produced at the normal treatment distance when field size is being determined.

Field size dimensions and SIDs shall be specified in inches or centimeters and shall ensure that aperture adjustments result in x−ray field dimensions in the plane of the image receptor that cor- respond to those indicated by the beam−limiting device to within 2% of the SID when the beam axis is indicated to be perpendicular to the plane of the image receptor.(d) X−ray systems designed for one image receptor size.

SO OPTION (C) FIELD SIZE IS COORECT ANSWER.

Answer 2

a) Field length

• The maximum number of characters needed to represent data in character format is indicated by the field length. If the data is saved in its native format, for instance, the int data type requires 4 bytes, the field length is already known. The bcp command prompts you for field length, the default field lengths, and the effect of field-length on data storage in data files that include char data if you have specified 0 for the prefix length.
• Microsoft generally advises accepting the default values recommended by bcp for the field length. Using the default field length while creating a character mode data file helps to prevent data truncation and numeric overflow issues.

Hence, option a is correct.
