Primary radiation barriers must overlap secondary barriers by at least:

In the posterior oblique projections of the cervical spine (RPO or LPO), the intervertebral foramina best demonstrated and open are those:

Which of the following is/are symptoms of inadequate oxygen supply? osteoporosis cyanosis dyspnea

If abdominal free air is demonstrated on an erect abdominal radiograph and an upper gastrointestinal series is requested, the contrast media of choice would be:

Standard disclaimer: use the algorithms from class, such as DFS, Explore, BFS, Dijkstra’s (using min-heaps), SCC, Kruskal’s, Prim’s etc., as a blackbox subroutine for your algorithm. If you attempt to modify one of these algorithms you will not receive full credit, even if it is correct. Make sure to explain your algorithm in words (no pseudocode!), explain the correctness of your design, and state and analyze its running time. Faster – and correct – solutions worth more credit. Design an algorithm to solve the following problem:Input: a connected, undirected, weighted graph G = (V,E), and a subset U of the vertices  .Output: a spanning tree of minimal weight in which the vertices of U are leaves (note that there might be other leaves in this tree as well).  

Which of the following system(s) function(s) to compensate for changing patient/part thicknesses during fluoroscopic procedures? automatic brightness control automatic kilovoltage control automatic resolution control

Methods that help to reduce the production of scatter radiation in a body part include using: Compression Beam restriction use of a grid

With the patient’s skull in the PA position and the OML and central ray perpendicular to the image receptor;    where will the resulting radiograph demonstrate the petrous pyramids?

Male guinea pigs can be differentiated from females by their longer anogenital distance.
