TABLE OF CONTENTS
"SonoFly"software, provided with SonoFly-3000, hard & software complex, allows :
- registration and storage of the data about patients;
- storage of US-images, results of measurements and calculations;
- compiling and electronic storage of examination reports;
Thus, the software allows to unite in the same database the results and experience of work during several years. Such approach gives an opportunity to watch the flow of illness and results of the treatment in dynamics, to store and compare the data obtained as the result of thousands of examinations.
Card File (Database) of Patients.
The software has simple interface and does not demand the user to have deep knowledge of computers. It is enough to master the major techniques of work with Windows applications. The main (star) window looks like this:
Figure 1.Main (Start) Window.
To the left (Fig. 1) there is the list of patients and controls for this list. Pressing the corresponding buttons you can add new entries to the card file, correct previous information, delete error entries and information, which is of no interest.
Figure 2. Window of New Patient Registration.
The entries are automatically arranged in the alphabetical order. The additional search function allows quick search of the patient’s name in the card file (Fig. 3).
Fig 3. Search Window.
The middle part of the window (Fig. 1) contains the list of examinations of the patient. The unit memory fixes not only the date of examination but also the conclusion pattern, data obtained during the examination and US-images. The controls under the list allow:
- to open the before saved examination report in order to view, correct or print it.
- to delete the examination report of no value.
- to add the next entry about an examination;
The appearance and the content of the text report (Fig. 4) depends essentially on the kind of examination, individual settings made by the doctor and some other parameters. It can look approximately like this:
Outlines: regular. Proportions: non-increased (Left Lobe-59mm. Right Lobe-100mm).
PARENCHYMA: Echogenicity unchanged. Echostructure unchanged. Sound conductivity regular.
Intrahepatic biliferous ducts undilated.
Portal Vein 10mm. Vessel sides unchanged.
Location typical. Dimensions 86õ27mm. Pear-shaped.
Wall thickness 3-4mm, hardened.
Contents – wall thick gall.
Choledoch 4mm, walls unhardened.
Dimensions 23õ13õ20mm (head/body/tail). Echogenicity increased. Echostructure.
homogeneous Wirsung’s duct 2mm. Splenic vein 7mm.
Location typical. Mobility of the right- regular.
Parenchyma 18mm, Echogenicity regular, Echostructure homogeneous.
Parenchyma 19mm, Echogenicity regular, Echostructure homogeneous.
Conclusion: Chronic cholecystitis. Chronic pancreatitis.
Doctor: Petrenko S.V.
To add new entry about examination means, in fact, to begin the next scan session. After you press the "Session" button, scan preparation window will appear (Fig. 5).
Fig 5. Window of Scan Preparation
On this window you can enter additional information about the patient – height,
weight, date of the first day of missed period. This data are represented then in the examination report
as well as used in some calculations.
Moreover, this window provides the choice of the type of examination. There in all exist six abstract registers to calculate the volumes of the organs and formations ellipsoid-shaped and six types of examination: cardiology, thyroid gland, obstetrics, abdominal cavity, prostate, mammas.
The pre-selection of the type of examination makes the preparation of the examination report easier. In other words it is an automatic selection of only those measurements and calculations which are peculiar for the necessary examination type from a rather vast list. In the session of cardiologic examination doctor will not have to be distracted by "biparietal dimensions of the fetus’s head" or "placenta thickness", though such parameters as "inal systolic dimensions of the left ventricle", "cardiac contractions frequency" etc. will be available.
he table bellow (Table 1) illustrates the connection between the selected examination type and corresponding measurements and calculations.
he list of available measurements, calculations and tables is constantly extended. Follow the news.
Table 1. Connection between the examination types and provided measurements and calculations.
|Type of Examination||Measurements Used||Calculations Provided|
|A (B, C, D, E, F)||Transversal, longitudinal, front-back dimensions (for each register)||Volume (for each register)|
|Cardiology||Final systolic dimensions of the left ventricle.
Final diastolic dimensions of the left ventricle.
Frequency of cardiac contractions.
|Final systolic volume of the left ventricle.
Final diastolic volume of the left ventricle.
Fraction of let.
|Thyroid gland||Transversal, longitudinal, front-back dimensions (for each lobe).
|Volumes of each lobe and total volume.
% of the average norm.
Departure from the extreme (max, min) values.
|Obstetrics*||he date of the first day of the missing period.
nternal diameter of the ovum (IDO).

*Obstetrics – the standards for estimation of pregnancy duration by separate indications can be changed. All current values are gathered in the table which can be viewed and corrected by pressing "OBSTETRICS " button. (Fig. 6).

Besides the selection of measurements and calculations, you can prepare and confront for each examination type a TEXT PATTERN of standard phrases, used in the conclusion (Fig. 7). This will help to reduce essentially the time necessary for typing examination conclusions.

The button SCAN in this window (Fig. 5) is used to go to a scan mode. The abilities of the program part, which operates this process, will be examined in the chapter US Scanning .
The US images saved during the session are an integral part of a card file. The list of images connected to an examination is represented in the left part of the main (start) dialogue box. One of the images (marked one) is represented as a miniature while the others are shown conventionally as rectangles. The software allows to view any of the images in the full-screen mode, to convert in into .bmp format, to print the images with the help of laser or ink printer, to delete the images which are not of value in the card-file.
The structure of the entry in the database can be shown as a scheme:

While working with a card file the context electronic help system is available. Press button "HELP" to open a corresponding chapter of the help library (Fig. 8).
