Intensity modulated radiotherapy IMRT is ideal for anal canal cancer ACC , delivering high doses to irregular tumour volumes whilst minimising dose to surrounding normal tissues. Establishing achievable dose objectives is a challenge. Each data set was planned by two different centres, producing 30 plans. All tumour and organ at risk OAR contours, prescription and dose constraint details were provided.

Short description Morphology Morphometrics Dorsal soft rays total : ; Anal soft rays : 14 - 15; Vertebrae : 37 - This species is distinguished from its congeners by the shape of the andropodium in males: sickle-shape spiculus is curved dorsally, the proximal and middle segments in contact with the distal tip of the third anal-fin ray; the spiculus' distal segments are curved ventrally, no contact to third anal-fin ray; in males, the second anal-fin ray with 3 or 4 segments proximal to paired spines, third or fourth segment with a dorsal and a ventral row of 'subsegments' forming squares and rectangles of different sizes, the third or fourth segment appears to be subdivided into two separate rays, from the half of its length up to the spines, with a varying number of subsegments? Nomorhamphus rex have a relatively longer lower jaw, LJLB 5. Occurs with Oryzias celebensis , Telmatherina cf.
