LectureVR v2.1.0 - Released: 12 February 2009 ================================================= Installation notes ------------------ Run setup program and follow on screen instructions Changes since ProjectionVR V2.0.0 --------------------------------- ability to angle the plane of the image receptor with respect to the central ray to demonstrate geometric distortions LectureVR v2.0.0 - Released: 07 Dec 2008 ================================================= The Lecture's demo tool has been separated from the ProjectionVR module and has been enhanced to form a module in its own right. This module is known as LectureVR. Installation notes ------------------ none Changes since ProjectionVR V3.1.9 --------------------------------- A selection of six regions of the body are available for selection. These include Head, Cervical Spine, Shoulder, Lumbar Spine, Pelvis and Knee. Hotkey "P" cycles through the available regions of interest. Hotkey "T" resets the orientation of the selected region of interest. Three levels of resolution are available for the generated image, low - 256 by 256 px, medium - 512 by 512, and high 1024 by 1024. These can be selected by the user at runtime to balance image quality and performance based on the users hardware capabilities. The "HQ" option has been removed. The "Beam Energy" setting has been improved The function of the key pairs "I"+"K", "U"+"O" and "J","L" has been altered. Previously these keys moved (or translated) the subject in the world space. With V2 these keys move the centre-of-interest of the subject with respect to itself. The centre is maintained in the line of the "central ray", which is always in the centre of the field-of-view, so the subject will appear to move. However the significance of this change is most noticeable when the subject is rotated, as it will rotate around its centre-of-interest. Also SID and OID measurements are taken from this point.
