Abstract: A system automatically synchronizes display of adjacent different medical image sequences of an anatomical portion derived for use in Angiography or another medical procedure. The system includes an imaging system for acquiring first and second sets of data at different stages of a treatment procedure representing corresponding first and second image sequences individually comprising multiple temporally sequential individual images of vessels of a portion of patient anatomy. The sequential individual images encompass introduction of a contrast agent into patient vessels. A display presents the first and second image sequences in substantially adjacent display areas to facilitate user comparison. A contrast agent detector automatically analyzes the first and second image sequences to identify a first image frame in both the first image sequence and the second image sequence indicating presence of a contrast agent.

Abstract: A method of operating a photosensor comprising: applying a bias voltage to a photosensor (12) comprising n (n>1) photo-sensitive elements (8) connected in series, and determining the photocurrent in the photosensor (12) at a time when the applied bias voltage across the photosensor maintains the photosensor at or close to the point at which it has the greatest signal-to-noise ratio. This may conveniently be done by determining the current in the photosensor at a time when the applied bias voltage across the photosensor is equal or approximately equal to n×Vbi, where Vbi is the bias voltage about which the current in a single one of the photo-sensitive elements (8), in the dark, changes sign. In an embodiment in which the photo-sensitive elements (8) are photodiodes, the bias voltage Vbi is the “built-in” voltage of the photodiodes. The photocurrent generated when n series-connected photodiodes are illuminated is approximately equal to the photocurrent generated when one photodiode is illuminated.
