Issue #1: when a single contour is saved in edit mode tumorloc does not save the contour in the correct location. the contour is saved in the location of the same slice where the last contour was drawn for the last region of interest (roi) in the roi list. a misplaced contour then results in a misplaced isocenter or incorrect field size. this occurs when using the save button exit button or sendtolaser button. issue #2: when the region of interest (roi) is displayed on the beam's eye viewer (bev) in outline mode and the roi color is changed the color is changed in the multi-planar projection (mpr) viewers but not the bev viewers. issue #3: tumor loc-created datasets are flipped and incorrectly labeled when non-gated data is loaded along with pulmonary gated data and is used to create intensity projection datasets (mip minip or avgip). if the clinician obtains a clinical intensity projection dataset in a certain manner a dataset can be generated that is flipped left to right. the resulting dataset is flipped and incorrectly labeled left-to-right when displayed in a viewer.Issue #4: duplicate region of interest (roi) or isocenter names can be created in tumor loc. this duplication is only possible when using the copy feature or manually naming a roi with the suffix " copy". this duplication can be created when creating a new isocenter or roi then creating another new isocenter or roi and naming the second isocenter or roi "firstname copy" (either manually or by clicking copy on the first isocenter or roi) where "firstname" is the name of the first isocenter or roi. if the user then selects the first isocenter or roi and clicks copy the resulting copy has the same name as the second isocenter/roi: "firstname copy".
