| what is a tomogram? | show 🗑
|
||||
| what is a tomograph? | show 🗑
|
||||
| show | the modality/ exam
🗑
|
||||
| show | synchonized movement of two elements, objects in plane of fulcrum sharp, objects farther away blurred
🗑
|
||||
| pivot point around the movement occurs, object being examined is placed at this point | show 🗑
|
||||
| show | fulcrum
🗑
|
||||
| method to overcome superimposition | show 🗑
|
||||
| show | tube, object, IR
🗑
|
||||
| terms used to describe section of interested in tomography | show 🗑
|
||||
| show | area of fulcrum is sharp because it has not moved in relationship to tube & IR during position
🗑
|
||||
| show | tomographic amplitude
🗑
|
||||
| show | exposure amplitude
🗑
|
||||
| show | only coronal slices
🗑
|
||||
| blurring of anatomic structures lying outside to focal plane | show 🗑
|
||||
| show | only the object lying in the focal plane
🗑
|
||||
| how is blur demonstrated on the tomogram? | show 🗑
|
||||
| how does blur effect density? | show 🗑
|
||||
| show | direct relationship. Increase in arc, increase in blur
🗑
|
||||
| show | directly. Increase in distance of an object from fulcrum, increase in blur
🗑
|
||||
| how is distance from IR related to blur? | show 🗑
|
||||
| show | blur increases
🗑
|
||||
| show | phantoms
🗑
|
||||
| show | during complex tomographic motion
🗑
|
||||
| show | phantoms
🗑
|
||||
| show | greater than or equal to
🗑
|
||||
| the exposure arc is greater or less than the tomographic arc? | show 🗑
|
||||
| show | reduced section thickness and increased exposure amplitude
🗑
|
||||
| pivot point | show 🗑
|
||||
| show | move table up or down OR move fulcrum up or down, patient remains stationary.
🗑
|
||||
| region within the image exhibits satisfactory recorded detail and is controlled by the fulcrum | show 🗑
|
||||
| show | width of the focal plane
🗑
|
||||
| show | inverse relationship- as angle increases, section thickness decreases.
🗑
|
||||
| show | tomography angle
🗑
|
||||
| controlled at the table, increments of 1/2 cm or 1 cm. | show 🗑
|
||||
| cannot exceed the section thickness | show 🗑
