A medical instrument (200, 300) comprising: - a medical imaging system (202, 302) for acquiring medical image data from an imaging zone; - a treatment system (206, 322) for depositing energy into a treatment zone, wherein the treatment zone is within the imaging zone, wherein the treatment system is operable for depositing energy into a subject; - a display for displaying a graphical user interface to an operator, wherein the graphical user interface is operable for receiving a halt command (274, 902, 904); - a processor for controlling the medical instrument; and - a storage storing machine executable instructions (250, 252, 254. 256, 258) for execution by the processor, wherein execution of the instructions causes the processor to receive a selection of a reference location; wherein execution of the instructions further causes the processor to receive a selection of one or more anatomical references, wherein execution of the instructions further causes the processor to repeatedly: - control the treatment system to deposit energy into the subject in accordance with a treatment plan; - control the medical imaging system to acquire the medical image data; - reconstruct a medical image (238, 264) using the medical image data; - determine cumulative dosage data (240, 270) at least partially from controlling the treatment system to deposit energy into the subject, wherein the cumulative dosage data is registered to the medical image; - determine a first registration which registers the reference location to the medical image; - determine a second registration which registers the one or more anatomical references to the medical image; - render the medical image in the graphical user interface using the first registrations to place the reference location in a predetermined position in the graphical user interface; - render a representation of the one or more anatomical references in the graphical user interface using the second registration; - render the cumulative dosage data in the graphical user interface, wherein the cumulative dosage data is superimposed on the medical image; and - control the medical imaging system to halt the deposition of energy into the subject if the halt command is received from the graphical user interface; wherein execution of the instructions further causes the processor to display a template display tool on the graphical user interface; wherein the template display tool is operable for selecting at least one template display plane position; wherein execution of the instructions further causes the processor to render the medical image in accordance with the at least one template display plane position using the one or more anatomical references as template parameters for automatically positioning the display plane positions. - a medical imaging system (202, 302) for acquiring medical image data from an imaging zone; - a treatment system (206, 322) for depositing energy into a treatment zone, wherein the treatment zone is within the imaging zone, wherein the treatment system is operable for depositing energy into a subject;
