Appendix I: Declaration of Conformity

 Targeted molecular imaging for

visualizing and quantifying the

expression of intravascular

molecular markers — for

example: angiogenesis and

inflammation

 Tumor perfusion and relative

quantification of vascular

volume and structure

 Assessment of myocardial

perfusion and area of infarction

CSV

Comma Separated Value (CSV) is a

file format used to represent

database fields. Each entry of the file

represents one field and is separated

from the next field by a comma.

DICOM

Digital Imaging and

Communications in Medicine

(DICOM) is a comprehensive set of

standards for handling, storing and

transmitting information in medical

imaging. It includes a file format

definition and a network

communication protocol.

Dongle

A hardware device that serves as

copy protection for the software by

rendering the software inoperable

when the device is not plugged into

a USB connector.

Doppler angle

The angle between the ultrasound

pulse and the direction of blood

flow. This angle is also known as the

incident angle to flow or the angle of

insonation.

ECG

Electrocardiogram is a electronic

representation of a physiological

measurement of the electrical

potentials of heart tissue. The output

is a trace of the heart rhythm.

Focal length

The distance from the active surface

of the transducer to the middle of the

focal zone.

Focal zone

The portion of a focused ultrasound

beam which is the region of optimal

resolution. The structure of interest

is optimally focused when it is

imaged within this region.

Frame rate

The number of acquisition image

updates per second in B-Mode. A

higher acquisition frame rate is

desirable when watching a moving

structure such as the heart, or when

moving the transducer.

M-Mode

M-Mode is used primarily to

measure the movement of structures

in the heart such as valves,

chambers, and walls.

MIP (Max)

Maximum Intensity Persistence

highlights the denser portions of the

volume by bringing them forward in

the image and making them brighter.

This more clearly displays a small

bright object in the middle of a dark

ultrasound image.
