    Abstract: Intravascular ultrasound techniques provide for intravascular imaging using contrast agents and nonlinear techniques. An ultrasound imaging device for detecting internal properties of a target body comprises an ultrasound transducer positioned at a distal end portion of a catheter, for transmitting excitation pulses and for receiving echo signals. A signal processor analyses echo signals at harmonics and/or subharmonics of the transmit frequency. The catheter may include a contrast agent delivery conduit extending along the catheter, the delivery conduit having an exit orifice proximal to the ultrasound transducer. The device may discriminate between echo signals respectively arising from interaction with tissue and from the interaction with contrast agent. The device may generate an image of the site of interest using non-linear components of the received ultrasound echo signals.

    Abstract: The invention relates to an inorganic rare-earth iodide scintillation material of formula A X Ln (y-y',) Ln' y' I (x+3y) in which: A represents at least one element selected among Li, Na, K, Rb, Cs; Ln represents at least one first rare-earth element selected among La, Gd, Y, Lu, said first rare-earth element having a valency of 3+ in the aforementioned formula: Ln' represents at least one second rare-earth element selected among Ce, Tb, Pr, said second rare-earth element having a valency of 3+ in the aforementioned formula, x is an integer and represents 0, 1, 2 or 3; y is an integer or non-integer greater than 0 and less than 3, and; y' is an integer or non-integer greater than 0 and less than y. This material presents a high stopping power, a rapid decay time, in particular, less than 100 ns, a good energy resolution (in particular, less than 6% at 662 keV) and a high luminous level. This material can be used in nuclear medicine equipment, in particular, in Anger-type gamma cameras and in positron emission tomography scanners.
