The former german physician Ryke Geerd Hamer and many followers of Germanic New Medicine count their diagnosis on a very particular interpretation of computer tomography brain scans of patients. This interpretation is not compatible with modern academic radiology. Hamer himself is not radiologist. In his books and on his webpages, he shows many brain scans but never shows details about the type of scanner used, exact date, or high voltage and exposure time used. He never shows the radiological findings and the reason why the scans were made. For a better understanding: In radiology, usually the left side of brain is shown on the right side, because a physician usually looks a patients into his face, standings before his feet. So he looks from downside to upside. Hamer presents his scans mirrored: the left side is seen on the left side of the picture.

Hamer believes that a sudden shock-like onset of unforeseen so called biological conflict leads to a so-called "Dirk-Hamer-Syndrome" (DHS), which immediately (within a fraction of a second) produces a "cancer" in an organ. He postulates that every DHS-related process will take place synchronously in the brain, in the «organic brain» and in the organ. He adds that the forming tumours are allegedly controlled by the part of the brain that is ontogenetically connected with the organ in question. Hamer calls this the «ontogenetic system of tumours». In the brain, the biological conflict is said to give rise to the development of a so-called «Hamer focus». By this, Hamer means structures seen in CT brain scans which are shaped like a shooting target, or a single, mathematically precise circle. He claims that the locations of the Hamer foci and their degree of severity are correlated with the organs affected, the underlying biological conflict and the phase of the conflict. The non-radiologist Hammer adds also that radiology was not able to detect these Hamer-foci until his inventions in 1981. According to new medicine, the patient's right- or left-handedness also plays a part.

The ring artefact (ring artifact)

Artefacts were quite frequent at the beginning of computer tomography, and a particular type of artefact, the ring-artefact (or ring-artifact) ^[1] was sometimes seen in early CT scanners, especially those of third generation and are very seldom today with progess in manufacturing scanners. These artefacts are machinery-caused shapes superimposing the underlying scan. Usually they are easy to recognize and can be avoided by complying with the indications given by the manufacturer. Ring artefacts are always precise and perfect dark and bright concentric circles. Sometimes they may appear only as segments of a perfect ring and sometimes only one single circle can be seen (if a specific single sensor is defective or not calibrated). The center of the concentric circels corresponds to the axis of rotation of the scanner and may be seen sometimes outside of the subject or object in the scanner. These circles are caused or by a defectous single sensor, a sensor with different sensibility than the other sensors or after having forgotten to calibrate the whole scanner. An old fashion CT-scanner had to be calibrated (with air or a water-phantom) at the beginning of service. After some hours a message told the operator to stop scanning and to perform a new calibration procedure as temperature influences and other effects were modifying slowly the performance of the single sensors. These sensors must work at the limit of sensibility to avoid too large doses of radiation for the patient. Knowing this, an expert CT-operator may also be able to produce artificial rings-artefacts as he wants by avoiding calibration or by manipulating the device.

The famous Siemens certificate December 22, 1989

Siemens document

Hamer and his followers often name a certificate of a german CT-manufacturer, the Siemens company dated December 22nd, 1989. And they believe that this paper would exclude the hypothesis that the Hamer-focus is in fact a tecnical artifact, namely a ring-artefact. But the opposite is true. This document can be used to identify ring-artefacts in many brain scans shown by Hamer. This documents does not deal with New Medicine or Hamer focus.

It was Hamer himself to request this document (!) in 1989 that was underwritten the day December 22nd.^[2] Hamer was one of the two underwriting people, the other beeing a Siemens engineer (not a radiologist). Hamer was at that time already barred as a physician since three years and had to face the reproval by radiologists and other physicians to show artefacts. This document tells from the point of view of Siemens several conditions that are not compatible with ring artefacts.

Translation: Erlangen, 22.12.89. Possible ring artefacts. The underwriting [Hamer and engineer Feindor] have developed 8 [in fact only 7] excluding criteria excluding the presence of ring artefacts. Not a ring artefact is present if

1. in MRI (Magnetic resonance imaging or tomography) an anlogue structure is visible [at the same location]
2. the circles are not perfect circular, but show impressions, having a correlation with dislocation of tissue [irregular circles]
3. a formation corresponds to glial tissue [part of the brain, not beeing out of neurons. Glial tissue never shows up in circles however - see literature. Detection is only possible by analyzing a tissue sample]
4. the center or the circles do not correspond to the axis of rotation of the scanner ("parazentrale Schiessscheibenkonfiguration"="paracentral") [term used by Hamer]
5. other circles aside [not beeing therefore concentric] are seen, only one can be a ring artefact.
6. the circle-structures have a clinical course [history], in other words: if they will be seen in the same location in future CT scans, but looking different.
7. scanner dipendent artefacts are ring-shaped structures or ring segment shaped structures around the axis of rotation of the sanner. If these structures can be confused with biological structures, it is recommended to repeat the scan with a lateral or vertical dislocation of the patient. If the structure will not appear in a different location, in respect to known anatomical reference point, it is not an artefact.

ing Feindor, RG Hamer

This Siemens document does not mention new medicine or Hamer and does not exclude the fact that Hamer shows ring artefacts in his books. The precise circular shape of many structures showed by Hamer correspond to point 2 in this document. There are no neuropathological reports that any of the Hamer-focus has ever been identified to be of glial-tissue according to point 3.

Expert opinion: Prof. Maximilian Reiser (University of Munich) in 2007

To professor professor Maximilian Reiser (University of Munich) and president of german radiologists (Deutsche Röntgengesellschaft) were presented some CT brain scans out of a book of Hamer. Reiser wrote in an expert opinion the day January, 22 2007:^[3]

expert opinion of Prof. Dr. med. Dr. h,c, Maximilian Reiser, director of the institute of radiology for clinical radiology of the Ludwig-Maximilian-University Munich, president of the Deutsche Röntgengesellschaft.

I willingly confirm you that the brain-scans presented in the "work" of Mr. Hamer have been interpreted in a completely inappropriate way by the author and are in clear conflict to scientifically justified knowledge and experience. An argumentative discussion with the content of Hamer's theories and the related interpretations of the brain scans is in my opinion not possible or lgoal-leading because Mr. Hamer is moving in a hermetically closed ambience of ideas and refuses any critic as expression of an arrogant "scolastic medicine". I would like to confim your corrections made in respect to some CT findings.

You may willingly cite this opinion as the opinion of the president of "Deutsche Röntgengesellschaft

With friendly regars, your M. Reiser

American radiologists discussing about Hamer-artifact ^[4]

The Swiss Study Group for Complementary and Alternative Methods in Cancer writes: ...The «Hamer foci» on the CT images in Hamer׳s books have been identified by radiological experts as typical artefacts produced by the radiological device which can appear in a poor-quality CT scan...^[5] and the author Sören Ventegodt (Denmark) adds: ..The concentric circles in the Hamer focus, shown on the front page of his book[1], looks like an artefact and very little as a biological phenomena, which in humans are almost never seen as concentric circles... ^[6].

Warning letters to German radiologists

The Association of German Radiologists (Deutsche Röntgengesellschaft DRG) issued a warning letter to all members. The radiologists should know, that some people would try to undergo a CT-scan for further evaluation by GNM-therapists, violating German RÖV-regulation because lacking any stringend indication. The same warning was also issued by other German Medical Associations ^[7]^[8]^[9].

CT brain scans presented by R.G. Hamer

The pictures are from his book: ^[10].

	page 209: clear evidence od a ring artefact with at least 7 concentric rings extending from one hemisphere to the other without displacing any tissue between them. It can be seen that the circles seem to enter and exit from the scull. These shapes have no biological origin. Hamer sees here a Hamer-focus in ca Phase.
	page 210: Another obvious and imposant ring artefact can be seen here with at least 10 mathematical perfect concentric circles extending from one hemisfere to the other without dislocating well known anatomical structures (like ventricles). The circles enter and exit the lateral walls of the skull. Hamer sees here a Hamer-focus after a separation-conflict had taken place.
	page 211: again an imposant ring artefact presenting at least 20 concentric circles this time. fissura longitudinalis is not dislocated at all, impossible from a radiologic point of view. According to Hamer, we see the brain scan of an italian patient of him (from Rome) with a Hamer-focus after been sued to have built an illegal house near Rome.
	page 212: Hamer sees here a Hamer-focus after separation conflict.
	page 215: According to Hamer we should see two different Hamer-foci. The upper-one would be is lysis, and the lower-one would be the result of an active separation conflict.
	page 217: ring artefact. Hamer sees here two Hamer-foci one inside the other.
	page 219: two ring artefacts, again easy to detect here.
	page 220: two ring artefact in every brain scan CT.
	page 223: two CT scans of the same patient (with alledged breast cancer) are presented, the quality is very poor however. Hamer says that the tecnician or radiologist made two scans and that the patient was moved laterally by 2 cm before the second scan was made to permit detection of possible ring artefact, but dubbling radiation dosis for the patient. No ring artefact can be seen on the two scans, these pictures are therefore useless to exclude artefacts. Normal gyri and fissures of cerebral cortex are seen (in very poor quality), cut by the CT-slices. The Hamer-focus on left seem to correspond to primary motor area or primary somesthetic gyrus of parietal lobus. The neutral obverser does not understand why Hamer designates a specific gyrus to be a Hamer-focus and does not the same with the other similar structures that can be seen.
	page 224: brain scans of a banker from London, presenting Hamer-focus.
	page 229: no artefact says Hamer.
	page 231: clear evidence of a ring artefact. Hamer argues that there were no artefact as the concentric formation would not be exactly circular.
